Redemption through Retrospect - 910 Words

Redemption Through Retrospect Patti Smith, a renowned American singer and songwriter, once said, â€Å"The idea of redemption is always good news, even if it means sacrifice or some difficult times.† In one’s lifetime, it is inevitable that one will face personal battles and experience feelings of guilt. One is able to find one’s peace of mind by redeeming oneself, by doing something that ultimately makes up for the cause of guilt. In the novel The Kite Runner by Khaled Hosseini, the story revolves around the two themes of betrayal and redemption. Ultimately, Hosseini exploits Amir’s odyssey to reveal the drastic transformation his character goes through from the moment he witnesses his best friend get raped to the day he runs a kite for his nephew Sohrab, repeating the same phrase Hassan said to him several years earlier. The storyline of The Kite Runner truly reveals how a flawed character can find redemption. Guilt drives Amir to embark on his search fo r redemption after he passively witnesses Hassan’s rape, and he strives to better his flawed character by repeating the same actions but from the giving end, stuffing money under mattresses to support others and running a kite for his nephew. When Amir sees Assef beating Hassan, Amir thinks, â€Å"I had one last chance to make a decision. One final opportunity to decide who I was going to be. I could step into that alley, stand up for Hassan-- the way he’d stood up for me all those times in the past-- and acceptedShow MoreRelatedThe Battle between Passion and Responsibility in Great Expectations964 Words   |  4 Pageschallenge his very integrity.

Things Fall Apart By Chinua Achebe - 969 Words

Joziah Dietrich Hour 4 Jonas 12/8/2015 My Way or No Way An intelligent motivational speaker, Peter Senge, once said People don t resist change. They resist being changed! As we go on in life, we come across two types of individuals, ones who see the chance to better themselves by making important changes, and ones who think there is no need for change due to the belief that everything about them is perfect. In the two books, Things Fall Apart by Chinua Achebe and The Tao of Pooh by Benjamin Hoff, the characters Okonkwo, Nwoye, and Pooh all illustrate the effects of accepting and or resisting change. In Chinua Achebe’s, Things Fall Apart, the character Okonkwo shows the negative outcome of resisting change. Due to a rough†¦show more content†¦Okonkwo continued to reject the ways of his father to the point where his â€Å"whole life was dominated by fear, the fear of failure and of weakness† (16). Okonkwo’s fear is what drove him to stay away from change and establish the ultimate goal of showing no resemb lance of his failure of a father. He showed great success by completing the goal and proving to the community that he was an entirely different individual. Although, his success quickly ended when he became close-minded when things didn t go the ways he wanted them to, leading to the downfall of his community. After the return from his 7 year exile, Okonkwo learned the missionaries changed all the people of his home town. â€Å"The clan had undergone such a profound change†(182) that they were barely recognizable, and as a result â€Å"he mourned for his clan†(183) because they had changed so much to the point where they seemed to be â€Å"soft women†(183). Okonkwo could not cope with such a drastic change, for change is what he was trying to stay away from. He had become a disgrace to his community, just like his father, who he refused to be like. By resisting change, Okonkwo lost the respect of his own father and the community that he thought were his people. The fear of change imposed great stress on himself over time, which lead to a breaking point and the taking of his own life. The refusal to change in little ways and accept different ideas is

From the Function of Music to Music Preference free essay sample

To date, not much is known about how the functions of music relate to music preference. This article examines the basic hypothesis that the strength of preference for a given kind of music depends on the degree to which that kind of music serves the needs of the listener; that is, how well the respective functions of music are fulfilled. Study 1, a pilot study, identified the best- known musical styles of the participants, yielding 25 styles that were known by at least 10 percent of them. Study 2 used these 25 styles and found that rock, pop and classical music were liked most.A factor analysis yielded six extinct dimensions of music preference. People showed great variation in the strength of preference for their favorite music. This is explained by the impact of different functions of music. The potential of music to express peoples identity and values and to bring them together was most closely related to the strength of preference. However, the reasons for liking a particular style are not congruent with the functions that people ascribe to their favorite music in general. A theoretical model of the development of music preferences is suggested. Unrest, musical taste, styles, uses and gratification approach KEYWORDS: Knowing more about music preference is essential for the music culture, for the society, [and] for the personal development of the individual (Finns, 1989, p. 43). The investigation of music preference consists of two central questions. First, why does one person like a certain type of music (e. G. , classical music) while another prefers a totally different type of music? And, second, why do people differ in their degree or strength of music preference, which can vary considerably?Good answers to both questions are necessary for building a sound theoretical model of the origin and development of USIA preferences. However, to date, the second question has received little attention. Let us first look at how preferences for a given type of music can be shaped. In his review of the literature on the topic, Finns (1989) concluded that there are several causal factors that can have an impact on music preference: specific characteristics of the music (tempo, rhythm, pitch, etc. ), familiarity and repeated listening, the listeners affective experiences while listening to music and social influences. Other researchers have provided further evidence for the impact of social influences (Adler, 1985; Slaking, Odds, Watts, 2006) and affective experiences (e. G. , Blood Equator, sampler 280 psychology of MusiC 37(3) 2001; Gibberellins, 2001; Guilin Alaska, 2004; Guilin Caseload, 2001) on music preference. And still others have found additional factors that can influence music preference: the personality of the listener (Reenters Gosling, 2003, 2006), the listeners physiological parameters (Mascara Ballard, 1999) and innate auditory preferences (McDermott Hauser, 2005; Tether, Challengers, Hill, 1997; Motto, 1997).And not least, the age of a listener seems to have a strong impact on music preference (Holbrook Schneider, 1989; Mender 1991). This list factors gives an idea how music preferences can be influenced, but the question remains why people actually listen to music and why they develop a special musical taste. If one looks at the research that has addressed the latter qu estion, the most general answers refer to the functions of music, which means that people use music to reach certain goals and serve their needs (e. G. Earnest, 1995; Back, 1993; Hexane, 1995; Larson, 1995; North Harvested, 1999; Caseload, ONeill, Vivaldi, 2001; George, Grant, George Gephardt, 2006). We will first discuss Hess research findings on the functions of music and then argue that the relationship between the functions of music and music preference especially the degree of preference still needs further investigation. Then we present the results of two studies. The first serves as a pilot study that provides the means to examine the relationship between functions of music and the strength of preference for different kinds of music in the second study.Finally, we discuss how the results obtained in the present studies might help to build a theoretical framework on the relationship of musical functions and music preference. Functions and benefits of music There is much evidence that the reasons why we prefer one type of music over another, or even like music at all, can be ascribed to the functions of music (Earnest, 1995; gene, 1 986, 1997; Guilin chukka, 2004 Larson, 1995; Lewis, 1992; Sartorially Erik, 2007; Schwartz gouts, 2003; Caseload et al. , 2001). Our daily lives are thought to be driven by certain needs that lead us to a state of subjective well-being or hedonism (see, e. . , Rises, 2004), and music is just one thing that brings us a bit closer to this end every day. We use music to serve several functions that are important to us. Most of the functions are related to developmental issues, especially for adolescents. Young people use music to explore, express and tighten their identities (Earnest, 1995; Larson, 1995; North Harvested, 1 999) and to communicate their personal values, ambitions, beliefs, and perceptions of the world and themselves (North Harvested, 1999; Steele Brown, 1 995; White, 1985). Through music people can try on different personalities or identities, including desirable ones as well as ones they fear (Larson, 1995; Markus Nurses, 1986). In this context, music is also used to establish a symbolic border against other groups (or against parents in early adolescence) to define a (youth) culture of its own (Back, 1 993; Rill, 2006). Music can enhance interactions with peers or with a partner, by providing either a medium for communication and common activities (e. G. , Denies, 1 992; Lull, 1992) or information about the other through his or her favorite music (Reenters Gosling, 2006).Reenters and Gosling (2003, 2006) found that listening to music is the top leisure-time activity for most people and they suggested that music is highly Downloaded from pomp. Seepage. Com at Universities Ethnology Mar (CCITT) on March 23, 201 1 Schafer and Sideliner: From the functions of music to music preference 281 diagnostic for exploring the personality of others. Further, music is used to tune out and to cope with daily hassles and problems (Earnest, 1 995; Larson, 1995; Schwartz Pouts, 2003; Taxman Hortatory, 2002).In a broader sense, we use music to manage and regulate our moods and emotions, to chill and relax, and to reminisce (George et al. , 2006; Guilin Alaska, 2001; Sartorially Erik, 2007; Ashrams Worth, 2006; Waterman, 1 996; Gilligan, 1988). People also use music to manage their arousal level or to satisfy their negation seeking (Earnest, 1992; Gnawing Mirror, 1999; Mascara Ballard, 1999), and music leads to physical activity through dancing. Functions of music and music preference Most of the studies that have investigated functions of music have used preferred or favorite music without considering the degree of preference.However, this pr ocedure makes it difficult to study the impact of functions of music on music preference: Why there is a continuum between just liking music and adoring music and whether and how this degree of preference is related to the functions of music has, to the best of our knowledge, not yet been addressed. In most of the research reported above, the assumption was made that the functions of music are directly related to preference, meaning that the more intensely music can be used to serve certain functions, the more intense the preference.However, this is not compelling, because music can be used in several ways, but not all of them appropriate for every listener. That is, someone might be aware of various functions his or her favorite music can serve, but this need not be the main reason for liking this music best. Thus, we have to look for the missing link between the functions of music and the degree Of music preference. A theoretical basis for investigating this relationship is provided by Been (1997, p. 49), who suggested that this relationship is linear that the intensity of music preferences seems to be a mirror of the intensity of Immensurable, defined as the sum of psychic processes which accompany the experience of music in situations when music is in the focus of interest (Been, 1997, p. 143). Following Been (1 997), we hypothesized that the strength of music preference should cavalry with the intensity of music use: the better the needs of a listener are served by a given music, the higher the degree of preference for that music should be.Rationale of present studies Our first step was to search for commonly known musical styles. Respondents were asked to list all musical styles known to them. This was done to obtain an overview of known styles to use instead of a ready-made list of styles collected by experts or a researcher, as has often been done. The best-known styles were then identified (Study 1). The next step (Study 2) was to determine if these styles could be grouped into a few dimensions of music preference to possibly confirm the results of previous research and to have a starting point for investigating the functions of music.Dimensions (factors) of musical styles (e. G. , rock, pop, rap, electro) refer to specific styles of music that are similarly rated or liked (e. G. , Bog, Racketeer, Volleyball, Well, Sickens, 2003; Burger, Gladiola, Lester, 2002; Christenson Peterson, Downloaded from pomp. Seepage. Com at Universities Ethnology Mar (Tim) on March 23, 282 Psychology of Music 37(3) 1988; Taxman Hortatory, 2002). In research, they are primarily used to reduce the number of different styles, especially to learn something about the perception of music and its impact on human behavior, emotion and cognition. For example, the genre rap might contain musical styles such as hip hop, black music, R n B, and rap. In a series of excellent studies, Reenters and Gosling (2003) showed that preferences can be grouped into only four dimensions that reflect the central characteristics of the music described: (1 ) reflective and complex (e. G. , classical); (2) intense and rebellious (e. G. , rock); (3) upbeat and conventional (e. G. , pop); and (4) energetic and rhythmic (e. G. , rap).Then we searched for the functions people ascribe to their favorite music and the relationship between these functions and their degree of preference, o learn something about what it is that makes them passionate listeners. The functions with the greatest influence on preference were identified via stepwise regression analysis. The functions used in Study 2 were derived from previous research on functions of music and were intended to cover all categories of functions music can have (except therapeutic).Preference for favorite music was investigated using questions concerning judgment as well as behavioral dimensions of preference in order to observe it in a more valid way, rather than a single scale of liking from not at all to very much. Study 1: how well known are different musical styles? Study 1 was conducted as a pilot study that investigated how well known different musical styles are, to provide the musical styles to be used in Study 2. METHOD In a questionnaire survey, 170 participants (100 female, 70 male) were asked to list, on paper, all the musical styles they knew.Participants were 15 to 78 years old (M 26. 4; SD 12. 2). Most (67. 1 were students at Chemist University of Technology in Germany (mainly in the social sciences, I. E. , psychology, sociology, pedagogy); 24. 7 percent were employed in various professions, and 8. Percent were sleepyhead or unemployed. Although we intended to have a balanced ratio of males and females, we received more answers from females, which is probably because social science students in Germany are predominantly female. Participants received no compensation for their participation.In addition to listing the musical styles they knew, participants estimated the mean time they spent listening to music every day and rated their musicality (scale from 1, very unmusical, to 10, very musical) as well as the importance of music in their life (scale from 1, not at all important, to 10, very important). R USE L T SAND IS CUE S S I ON There were 74 different musical styles, each known to at least one participant. To narrow the field for further investigation, styles were selected that were known by at least 10 percent of all respondents, which resulted in 25 styles (see Table 1).Respondents mean rating for self-estimated musicality was 6. 1 (SD 2. 4), and the mean rating for importance of music in their life was 8. 2 (SD 1. 8). Thus, participants rated their own musicality as moderate, yet music seems to play a very important role in their life. This is emphasized by the reported time they spent listening to Downloaded from pomp. Seepage. Com at Universities Ethnology Mar (Tim) on March 23, 2011 Schafer and Sideliner: From the functions of music to music preference 283 music per day, which was about three hours (M 2. 9; SD 1 . ). The duration of music listening was slightly negatively correlated with age (r . 15; with a sample size Of n 170, and a one-tailed Of 5 percent, correlations are significant if r . 13) but more and positively with musicality (r . 24) and importance of music (r . 29). As suggested by previous findings (Mended, 1 991), importance of music decreased with age (r . 24). This is further supported by a negative relation between age and the number of styles mentioned (r . 30). Musicality was moderately correlated with importance of music (r . 39).To reveal possible effects of gender, we used t-tests to compare the mean values for musicality, importance of music and amount of time of music listening per day of males and females. Despite the relatively high power because of the large samples, none of the tests were significant. The same holds for comparisons of the Fisher z-transformed correlations (e. G. , Rosenthal Orison, 1991, p. 495) calculated separately for males and females. Thus, gender effects were negligible in our study. The list of best-known musical styles was used as a starting point for Study 2. It provides a valid representation of styles familiar to the respondents.In Study 2, a larger sample was investigated; this is why Study 1 covered no further questions.

METHOD Participants In this study, 507 participants from several German cities responded to an online survey via the internet. They were 11 to 50 years old (M 24. 8; SD 5. 1); 71 percent were female, 29 percent male. Most (79. 5%) were students of various disciplines (mainly in the social sciences, I. E. Psychology, sociology, pedagogy), 15. 6 percent were employed in various professions, and . 9 percent were self-employed or unemployed. Thus, the respondents in this sample were somewhat younger than those in Study 1 and there were more students. Again, participants received no compensation for taking part in the study. As in Study 1 respondents had to provide information about their musicality and the importance of music. The results were consistent with Study 1 for self-estimated musicality (M 5. 7; SD 2. 4), the importance of music in their life (M 7. 7; SD 1. 5), and the mean duration of listening to music per day (M 3. 1 hours; SD 2. 5).Again, the duration of music listening was slightly actively correlated with age (r . 14) but more ? and positively ? with the importance of music (r . 33). However, it was not correlated with musicality (r . 07). Importance of music did not decrease with age (r . 08), which is a clear difference from Study 1 and probably because of the younger sample in Study 2. Musicality was moderately correlated with importance of music (r . 41). As in Study 1 to reveal possible gender effects we ran t-tests for musicality, importance of music and amount of time of music listening per day, and we compared all correlation coefficients between males and females. None of these differences were significant.Thus, again, gender effects were negligible. Material and procedure The questionnaire was provided via the internet and completed online. All materials were originally in German. The link to the website was distributed via email to mailing lists Of German universities, and all respondents were encouraged to forward this link to their friends and relatives. First, participants were asked to give preference ratings for each of the 25 musical styles from Study 1. This was done on ID-point Liker scales with the poles (0-9) labeled l dont like it at all and l like it very much. Then the respondents were asked to name their favorite music (not restricted to the 25 given styles).To provide information about music preference, including attitudes as well as behavioral dimensions, they were asked to rate how much they agreed with the following statements: (1) l like this music, (2) I couldnt live without this music, (3) l regularly visit clubs or concerts to listen to this muse, (4) l just need this music, (5) Im a passionate Downloaded from pomp. Seepage. Com at Universities Ethnology Mar (Tim) on 285 listener of this music, (6) l usually spend a lot of money to purchase this music. This was done on 1 a-point Liker scales with the poles labeled do not agree at all and completely agree. Following this, respondents were asked to think of their favorite music and rate how much they agreed with several statements about it (the functions of music as found in the literature, see Table 2).Again, 1 a-point Liker scales were used with the poles labeled not agree at all and completely agree. Participants then had the opportunity to name additional functions of their favorite music that were not on the list. Rest Its and discussion The structure of music preferences The 25 best-known musical styles were dated for preference. Despite the limitations (the somewhat younger sample and the missing correlation between the importance of music and age in Study 2), the overall correspondence between the two samples seemed to be high enough to use the 25 best-known musical styles from Study 1 in Study 2. Figure 1 shows the rank-ordered mean preference ratings.The most favored styles were rock and alternative, followed by classical, pop, rock n roll, jazz, punk, reggae, blues and ask. Styles that were judged rather negatively were beat music, folk and the various kinds of electronic music. This reflects and extends previous findings about the popularity of musical styles, namely, that rock, classical and pop music are very popular styles (e. G. , Been, 1986; Mended, 1991) but that folk music does not play as important a role for Germans as it does, for example, for Turkish people (Taxman Hortatory, 2002). Previous research has repeatedly revealed a structure of music preferences, meaning that certain musical styles are perceived or rated similarly.

Critique the Constitutional Provision for Press Freedom in Nigerian 1999 Constitution free essay sample

In America they say freedom of the press is democracy. With more than 100 national, local, and state-owned newspapers and publications; print media in Nigeria is one of the most vibrant in all of Africa. While on a superficial level, it appears the media in Nigeria enjoy a considerable freedom, in reality however, independent journalism is not as common as it may appear. Despite the transition from military to civilian rule in 1999, clampdown, assault, beatings, unfair arrests and police raids of media house has continued. Between June 2002 and September 2003 alone Media Rights Agenda (MRA), a Lagos based nongovernmental organization which promotes press freedom and freedom of expression, recorded more than fifty cases of reported abuses against journalists and other violations of freedom of expression. The media watchdog Reporters Without Borders in 2010 listed Nigeria Police Force as the leading abuser of journalists’ rights. On Saturday, April 24, 2010, Edo-Ugbagwu, a judicial correspondent of The Nation newspapers was murdered in Lagos. Also, Godwin Agbroko and Abayomi Ogundeji of Thisday newsapeprs, Omololu Falabi and Bayo Ohu of The Guardian were all brutally killed in Lagos by unknown gun men recently. All these killings and the initial reluctance of the national assembly and the president to pass the Freedom of Information Bill have further raised the question of press freedom once more in Nigerian democracy. The assault on the press is a fundamental breach on democratic norms and serves to remind Nigerians of the dark days of impunity during the Military era. Justification for Press Freedom in Nigerian 1999 Constitution Nigeria is operating now as a democracy so the freedom of expression including freedom to hold opinions, receive and impart ideas without interference should be a fundamental right guaranteed under the Universal Declaration of Human Rights (UDHR), the African Charter On Human and Peoples Rights, (ACHPR), the Constitution of the Federal Republic of Nigeria 1999 and other regional and international treaties to which Nigeria is privy. Moreover, Section 39 (1) of the 1999 Constitution of the Federal Republic of Nigeria provides: Every person shall be entitled to freedom to hold opinions and impart ideas and information without interference. There is a reason why press freedom is included in the Nigerian constitution. The idea behind freedom of the press is that an informed public has a fighting chance against any government who will like to possess complete power over them. According to established human rights provisions it is quite clear these acts of intimidation and harassment are unconstitutional, an abuse of due process, and a negation of the gains so far made in Nigeria’s fledgling democracy. Democracy flourishes under a free press. It is a system that provides for the right to freedom of expression. And it is the foundation upon which rests other freedoms. If politics is about development and the ultimate goal of any political system is to ensure the improvement of the security and welfare of the citizenry, then the resort to assault on the Media negates fundamental rights and the rule of law. It merely demonstrates impunity, and intolerance to alternatives views. The brutal murder of Dele Giwa should specially be remembered this day and the question repeated: who killed Dele Giwa? The prime suspect in the murder, Ibrahim Babangida, should be made to answer this question as he prepares to run for the presidential election. When it is impossible to retort through the media, any injustice occurring against the people by those they supposedly voted in to advance their wellbeing, it means the country is headed down the road of totalitarian rule. In the last 12 years since the return of the country to civilian rule, the Nigerian Press has been under serious threat by Law enforcement agencies and other government organizations. When Channels Television was closed in 2008, the CEO John Momoh apologised to the government but the initial suspension of its license over a story on the purported plan of President Umaru Yar’Adua to resign was a sign of an unspoken threshold beyond which criticism is not tolerated in Nigeria. (Who knows what that purported resignation would have been the best of the sick president? Limitations to Press Freedom in Nigerian 1999 Constitution The 1999 Constitution of the Federal Republic of Nigeria grants to Nigerians the Right to Freedom of Expression and the Press. In Section 39 (1) it states: â€Å"Every person shall be entitled to freedom of expression, including freedom to hold opinion and to receive and impart ideas and information without interference. † However, in sub-section 3, th e same constitution takes away with the left hand what it had granted with the right hand in section 39. Sub-section 3 states: Nothing in this section shall invalidate any law that is reasonably justifiable in a democratic society: (a) For the purpose of preventing the disclosure of information received in confidence, maintaining the authority and independence of courts or regulating telephony, wireless broadcasting, television or the exhibition of cinematography films or (b) Imposing restriction upon persons holding office under the government of the federation or of a state, members of the armed forces of the federation or members of the Nigeria Police Force or other government security services or agencies established by law. In chapter 2, titled Fundamental Objectives and Directive Principles of State Policy, Section 22, the Constitution imposes some obligations on the mass media. It states â€Å"The press, radio, television and other agencies of the mass media shall at all tim es be free to uphold the fundamental objectives contained in this chapter and uphold the responsibility and accountability of the government to the people. † But how is the press supposed to discharge these weighty responsibilities if its voice is padlocked not only by the limitations contained in sub-section 3(a) and (b) of section 39 but also by the Official Secrets Act, 1962, and other enactments? Clearly, the Official Secrets Act prevents a journalist from receiving and or imparting information that is available to a government official by the virtue of his office. Section 1 of that Act makes it an offence for a person to transmit any classified matter to a person to whom he is not authorized on behalf of the government or to reproduce, retain or obtain any classified matter. Section 2 brings down the hammer on a public officer who avails any unauthorized person of classified matter under his custody or control by pronouncing him guilty of an offence. But secrecy in matters of public interest is a violation of the principle of the peoples right to know. It is also antithetical to the principles of transparency and accountability in governance. * Defamation: this include Libel and Slander: In Law â€Å"Libel† refers to everything printed or written which reflects on the character of another, and is published without lawful justification or excuse, whatever the intention may have been, while â€Å"slander† on the other hand was described as A false and defamatory statement concerning a person made by word of mouth or in other transient form. Sedition: Sedition is a comprehensive term and it embraces all those practices, whether by word, deed or writing which are calculated to disturb the tranquility of the state, and overthrow the government. When therefore any write-up or speech or any device of communication whether by sign, tapes, caricature etc, that has the effect of producing any of the above, such a write-up notwithstanding the constitutional freedom of expression amounts of sedition.

Literature Review of Fal-G free essay sample

CHAPTER. 2 Literature review GENERAL Fly ash is a waste product from thermal power plants where pulverized coal is used for the as per the literature review GouravHYPERLINK http://biblioteca. universia. net/autor/Gourav,%20K. html,  Studies, 2007. Fly ash is being utilized in the blended cements, additive for concrete and manufacturing of concrete blocks and bricks. Fly ash-lime-gypsum bricks are being manufactured and marketed throughout the country. The literature review on fly ash-lime-gypsum (FALG) mixtures as intended to manufacture bricks or blocks for masonry applications indicates several gaps in understanding the various aspects of the technology. The present thesis is an attempt to understand the behavior of compacted stabilized fly ash mixtures for the manufacture of fly ash bricks and characteristics of masonry using such bricks. A brief introduction to the technology of compacted stabilized fly ash bricks for structural masonry is provided. The main focus of the investigations is on arriving at the optimum stabilizer-fly ash mixtures considering density, stabilizer-fly ash ratio, curing conditions, etc. We will write a custom essay sample on Literature Review of Fal-G or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page as the variables. Therefore the parameters/variables considered in the investigation include: (a) density of the compacted fly ash mixture, (b) stabilizer-fly ash ratio, (c) curing duration (normal curing and steam curing) and (d) dosage of additives like gypsum. The investigations clearly show the possibility of producing bricks of good quality using compacted fly ash-lime gypsum mixtures. Wet compressive strengths of 8- 10 MPa was obtained for compacted fly ash-lime-gypsum bricks at the age of 28 days. Wet strength to dry strength ratio for these bricks is in the range of 0. 55 – 0. 67. Initial tangent modulus for the fly ash-lime-gypsum bricks in saturated condition is in the range of 8000 – 12000 MPa. There is a large scope for selecting optimum mix ratios of Fly ash, sand, lime and other additives to obtain a specific designed strength for the brick. The thesis ends highlighting major conclusions of the investigations. A general study conducted on M30 strength of neat FaL-G has indicated that 1. 5 times of its dosage by weight, as against OPC, keeping the other aggregate same, renders a mortar or concrete of parallel grade strength. A Study on workability for M15 grade concrete has not shown any slump, unlike OPC. The additional 50% input of FaL-G cement might have rendered relatively better cohesion for wet concrete to show this phenomenon. Hence a different approach to study workability of FaL-G concrete has to be developed. Even at low workability, this can be considered as roller compacted concrete. FaL-G can replace OPC in many avenues. The reinforcement behavioral studies in reinforced FaL-G cement concrete (RFCC) are in progress but the postulations indicate that the constituent of FaL-G being 1. 5 times more than OPC by weight which in other words 3 times by volume of account of two to one ratio in densities, the specific area of cement matrix is relatively larger in RFCC than in RCC. Thereby reinforcement is more closely coated with cementitious gels and more safely ensured for water impermeability to veto the chances of corrosion. However FaL-G is weak abrasive product hence may be avoided on high abrasive prone areas, till its abrasive resistance is virtually improved. It is cheap in cost; transportation cost can be reduced by decentralizing the FaL-G cement activities. Fly ash-based brick and cement are far superior in engineering properties over their conventional competitors. This knowledge needs to be disseminated globally, more so in second and third world countries, through tangible technical explanations (Bhanumathidas and Kalidas 2003). Although results of FaL-G bricks and hollow blocks were promising, and the technology could not be implemented due to initial consumer resistance in adapting to new materials. Ambalavanan and Roja (1996) in their study of FaL-G bricks utilized waste lime and gypsum with fly ash. They have observed that in most cases the use of waste lime does not give technically desired results and some improvement is needed to increase the strength of FaL-G bricks. The treatment to be given to waste lime increases the cost of FaL-G bricks significantly as compared to conventional bricks, which is hindering the commercialisation of this new material. Some researchers have reported that there is fall in strength in FaL-G composites at later age. This aspect should be considered in the field application of FaL-G products. For wider application of FaL-G bricks and hollow blocks in the housing sector, extensive research is further needed. ENGINEERING MECHANICAL PROPERTIES OF FAL-G Radhakrishnas (2010) preparation of FAL-g composite included both blocks cubes, with different parameters like finesse of fly ash, aggregate to binder ratio, degree of saturation, age testing the blocks and cubes for unconfined compression to determine the compressive strength. The strength data was generalized for a reference value of water-to-FaL-G ratio. A phenomenological model was developed to account for synergy between the materials used. Its robustness was verified with an independent set of experimental data. The predicted strength values are in close agreement with the experimental strength. He reinforced the possibility of using the model in the field to re-proportion the FaL-G mix of any consistency. Ismail Demur and Serhat Baspinar, 2007: investigated the effect of different type of pozzolan additions to cement free lightweight block made from fly ash–lime–gypsum mixture and observe the changes in physical, mechanical, thermal properties and microstructure Thermal conductivity of the fly ash–lime–gypsum mixture was improved by the addition of the expanded perlite. Optimal strength-thermal conductivity combination was obtained by the usage of silica fume and expanded perlite together. Improved strength properties were obtained by using hydrothermal curing conditions and super plasticizer addition. Mingjie Hua et al, 2009: conducted test using- -new type of semi-rigid road sub-bases. , which is a mixture of FGD gypsum, water glass and slaked lime. They studied molded samples of this new material investigated using different curing methods and measuring unconfined compressive Strength, soundness and water stability. Their team showed that the road sub-base material reflects excellent mechanical properties and soundness durability. S. K. Antiohos et al; 2007: In their test they studied Mechanical and durability characteristics of gypsum-free blended cements incorporating ulphate-rich reject fly ash. No gypsum was added in the mixtures, since it is believed that sulphate ions necessary for the prolongation of the setting process (commonly provided by gypsum) could be provided by fly ash enriched in sulphates. Their tests results revealed that waste materials not up to relevant standards could still contribute to the production of quality products of energy and economical efficien cy. * This article is not included in your organizations subscription.

D. P. Benz et al; (2010); presents paper about thermal Properties of High-Volume Fly Ash Mortars and Concretes. Paper focuses on a characterization of the thermal properties, namely specific heat capacity and thermal conductivity, of such mixture. Because the specimens being examined are well hydrated, estimates of the specific heat capacity based on a law of mixtures, with a â€Å"bound specific heat capacity value being employed for the water in the mixture, provide reasonable predictions of the measured performance. Observed measured values should provide a useful database for evaluating the thermal performance of high volume fly ash concrete structures. RESEARCH PAPER 1999: points about the effects of processing and materials variations on mechanical properties of lightweight cement composites. The mechanical properties were improved by increasing the amount of silica fume, fly ash, and fibers. Paper says both carbon fibers and alkali-resistant glass fibers were effective in reinforcing the matrices, but carbon fibers were superior to glass fibers. Fabrication techniques for producing lightweight cement composites that can substitute for autoclaved lightweight concrete was developed. Md. Moinul Islam1and Md. Saiful Islam 2010: did research about Strength Behaviors of Mortar Using Fly Ash as Partial Replacement of Cement. Concrete Research Letters Vol. 1(3) this paper reports the results of an experimental investigation carried out to study the effects of fly ash on strength development of mortar and the optimum use of fly ash in mortar. His test results show that strength increases with the increase of fly ash up to an optimum value, beyond which, strength values start decreasing with further addition of fly ash. Among the six fly ash mortars, the optimum amount of cement replacement in mortar is about 40%, which provides 14%higher compressive strength and 8% higher tensile strength as compared to OPC mortar. Jia-sheng Chen1 et al; February 2010: His study results show that yellow phosphorus slag can be used as the cement substitute for potential coagulation property. The hydration reaction involves hydration stage, solidifying stage, and strength stage with Ca (OH) 2 as the activating agent.

Maitra et al; 2005: Effect of heat treatment on properties of steam cured fly ash-lime compacts was studied. Kinetics of thermal dehydration of the compacts was also studied from thermo gravimetric measurements under non-isothermal condition to ascertain the order of dehydration process and the associated activation energy. Seema Karami1 et al; 2010: Research was undertaken to study the effect of sulphate activation of Run of Station Ash (ROSA) blend with Red-Gypsum (RG), Plaster Board Gypsum (PG) and By-Pass Dust (BPD). Research on Fly ash, Lime and Phospho gypsum (FaL-G) reported that when gypsum was added to Fa-L mix, the compressive strength increased by 3 and 22 times in comparison with that of Fa alone and Fa-L at 28 days curing time, respectively [A. Ghosh and Ch. Subbarao, 2001]. FaL-G is a hydraulic binder that was used for bricks and hollow blocks [Kumar, 2002]. Analysis of aerated concrete block wall; construction quality control; paper gives information about aerated cement concrete blocks are made of , lime, gypsum and fly ash, or river sand as the main raw material, aluminum is made by the gas-foaming agent, molding, maintenance and other craft made of autoclaved porous block walls material. As a load-bearing and non load-bearing structural materials and thermal insulation envelope materials, with a light weight, thermal insulation, sound insulation performance is good; there is a certain mechanical strength and process ability advantages. This paper discusses the aerated concrete block wall construction quality control points. | ENVIRONMENTAL FACTORS PapitaSaha ShyamalKSanyal;2010;The present contribution deals with the removal of cadmium ion using clay soil mixed with different admixture (cement, gypsum, lime, bentonite) as adsorbent in laboratory scale experiment. In continuous experiment it was observed that the % removal was 95–99%. A mathematical treatment of this adsorption phenomenon has been developed and it was observed that the experimental results showed satisfactory agreement with the theoretical predicted results. M. Ahmaruzzaman; 2010: In this paper, the utilization of fly ash in construction, as a low-cost adsorbent for the removal of organic compounds, flue gas and metals, light weight aggregate, mine back fill, road sub-base, and zeolite synthesis is discussed. The adsorption capacity of fly ash may be increased after chemical and physical activation. Converting fly ash into zeolites not only alleviates the disposal problem but also converts a waste material into a marketable commodity. Investigations also revealed that the unburned carbon component in fly ash plays an important role in its adsorption capacity. Future research in these areas is also discussed. | As per the experimental studies done by S. Geetha, Ramamurthy; 2010: Chemical activation is done using Na2SO4 to enhance the strength of the cold-bonded aggregate by accelerating the pozzolanic reaction and formation of more ettringite. It was observed that increase in binder and Na2SO4 dosages increased the strength and decreased the open porosity thereby reducing the water absorption As per, Lal C. Ram Reginald E. Masto; 2010: Studies the application of FA has improved the physical, chemical and biological qualities of soil to which it is applied. FA generated in India tends to be mostly alkaline, with lower levels of trace elements than are often found in FAs from other countries. The concentrations of potential chemical stressors, predominantly metals, in Indian FAs are often less than established or proposed permissible limits and are thus better suited for soil application. A major logistic limitation to the use of FA could be the cost involved in transport of ash from production to utilization sites. High Volume Fly Ash Concrete and Its Mechanism Posted: 2009- It is known that the fly ash emissions from industrial by-products are very large. To fully exploit the potential activity of industrial waste, fly ash has to be used to reduce the amount of cement concrete. To reduce the Cost of production; turning waste into treasure, of harm into, saving a lot of valuable land dumping of fly ash; a greater degree of high performance edge, to improve concrete workability, durability, and physical and mechanical properties we have to use Fly Ash Concrete In one embodiment the invention provides solid bricks produced by compressing together fly ash, bottom ash, gypsum, calcium carbonate, and lime. These bricks have sufficient structural strength for use in building and construction. In another embodiment, waste materials are encapsulated in a mixture of fly ash, bottom ash, gypsum, lime, and calcium carbonate and compressed into bricks that may be disposed of in an environmentally acceptable manner. Further, the compressed bricks containing waste material may be coated with an impermeable membrane of a synthetic polymeric material. Further, the invention provides a mobile, trailer-mounted apparatus for compressing the mixtures into bricks. Mohammad M. Khabiri; 2010: studied the effect of Stabilized Sub base, Containing Waste Construction Materials on Reduction of Pavement Rutting Depth, examined the changes of rutting depths due to using from stabilized Recyclables materials. Milken et al; study investigates the feasibility of using coal fly ash and fly ash-bentonite mixtures as a barrier material for mine waste. Tara Sen and Umesh Mishra; 2010: studied, applications of industrial wastes considered in road construction with great interest in many industrialized and developing countries. The results of this study suggest that the addition of 10% bentonite to coal fly ash reduced the hydraulic conductivity of the coal fly ash to less than 1_10? 9 ms and improved the chemical compatibility for mine waste containment. Use of these materials in road making is based on technical, economic, and ecological criteria. Various Industrial wastes for use in the construction of highway have been found to be successful. ECO-FRIENDLY BUILDING MATERIALS AND TECHNOLOGIES. Eco-housing Assessment Criteria 2009. Information about Fly Ash Lime Gypsum Brick. Fly ash-lime-gypsum bricks / blocks are very good products, giving the highest strength among various bricks. These require relatively higher investment and expensive raw materials to give arrange of high strength products. This is most suitable for mechanized operations, though semi mechanized operations are also possible. Fly ash lime gypsum bricks are made up of 60% fly ash, 10-20% lime and 10-20% gypsum. These bricks have medium range strength. Minimum compressive strength (28 days) of 70 kg/cm2 can easily be achieved and this can go up to 250 Kg/cm2 (in autoclaved type). Advantage of these bricks over burnt clay bricks: Lower requirement of mortar in construction, Plastering over brick can be avoided, Controlled dimensions, edges, smooth and fine finish can be in different colors using pigments and cost effective, energy-efficient environment friendly (This avoids the use of fertile clay). Polycor Vetrazzo; -2010: did research about recycled material investigates the composition preferably used for recycle that is Fal-g and observes, has high recycle content. The sheet-form material made in accordance with the invention can be used to provide exposed solid surfaces, for example, surfaces for shower walls and floors, counter-tops, table-tops, and the like, where low hydraulic permeability and high compressive and tensile strength are required. The cement content is relatively low, preferably in the range of about 3% to 20% by weight, and the pozzolan to cement ratio is relatively high, preferably equal to or greater than unity and can be suitably used as alternative construction material. Godfrey MadzivireLeslie et al; 2010: studies about Balfo Application of coal fly ash to circumneutral mine waters for the removal of sulphates as gypsum and ettringite. They observed Subsequent treatment of circumneutral mine water to pH greater than 11 resulted in more than 60% sulphate removal. Treatment of circumneutral mine water to pH greater than 11 with FA followed by seeding with gypsum crystals and the addition of amorphous Al(OH) 3 resulted in removal of sulphate to levels below the Department of Water Affairs and Forestry (DWAF) water quality effluent limit (500  ppm0). Keat-Teong LeeKok-Chong Tan, et al, 2007, they devised a Model that was found useful to predict the daily operation of flue gas desulfurization processes by using CaO/CaSO4/coal fly ash sorbent to remove O2from flue gas. Puvvadi V et al; 2010: studied about Gypsum treated fly ash as a liner for waste disposal facilities. They investigated the use of gypsum, which is known to accelerate the unconfined compressive strength by increasing the lime reactivity, and further improving the hydraulic conductivity. They made an attempt in the present context to reduce the hydraulic conductivity by adding lime content up to 10% to two selected samples of class F fly ashes. They investigated that the higher amount of lime in the presence of sulphate is observed to produce more cementitious compounds which block the pores in the fly ash. The consequent reduction in the hydraulic conductivity of fly ash would be beneficial in reducing the leach ability of trace elements present in the fly ash when used as a base liner. J. Sanjurjo Sanchez et al. 2010. Studied about the deposition of particles on gypsum-rich coatings of historic buildings in urban and rural environments and made comparisons. They studied XRF and SEM analyses of these coatings and their comparison with both the composition of dust coatings formed by the deposition of gaseous and particulate matter in an urban and a rural locality allows assessing which pollution sources are the most damaging for these materials, knowing the elemental composition of these emissions. Aly Ahmed et al; 2011: did Investigations of using recycled gypsum â€Å"bassanite† which is derived from gypsum waste plasterboard and waste plastic trays for ground improvement; this can be also used for soil improvement. Recycled gypsum content, curing time and frost heave property throughout capillary rise test were investigated to determine the behavior of treated soil with recycled gypsum. In addition, size, content and aspect ratio of strips of waste plastic trays were investigated. Adding strips of waste plastic trays to samples treated with recycled gypsum enhanced both splitting tensile and compressive strengths as well increased the value of secant modulus. The size and content of strips of waste plastic trays have significant effect on the potential of capillary rise and the enhancement of strength and stiffness of tested soil.

The paper deals with studies on select wastes like phosphogypsum and chalk for use in value-added building materials. The engineering properties and techno-economics of materials like gypsum plasters, cementitious binders, boards/blocks, masonry cement and flooring tiles produced from phosphogypsum and lime have been detailed. They came to the conclusion that the production and use of building materials from such wastes will protect the environment from degradation. The disposal and use of solid industrial wastes like phosphogypsum, fluorogypsum, fly ash, and slag can be met successfully. Activation or strengthening of fly ash-lime with gypsum Yang MinQian Jueshi and Pang Ying; 2007:studied about the Activation of fly ash–lime systems using calcined phosphor gypsum also experiments were performed to determine the effect of calcined phosphogypsum on the strength of fly ash–lime binders.

Kelly RuschTingzong Guo and Roger; 2002: They investigated how best PG can be stabilized with class C fly ash and lime for potential use in marine environments. Development of the ruptures in the composites must be considered when the composites are used for aquatic applications. They came to the conclusion that effective diffusion coefficients and effective diffusion depths alone are not necessarily good indicators of the long-term survivability of PG: class C fly ash: lime composites. Larbi Kacimi Martin Cyrand Pierre Clastres; 2010: The objective of this study was the synthesis of L-C2S (Ca2SiO4) belite cement, starting from fly-ash of system CaO–SiO2–Al2O3–SO3, and using the hydrothermal method in alkaline solution. The optimization of the synthesis parameters (temperature and time of stirring, pH of solution, temperature and duration of mixture burning) was also studied. The results obtained showed that these ashes could form belite cement composed of only one dicalcium silicate phase ( L-C2S). Bhanumathidas and Kalidas; 2004: They studied the Point of View Dual role of gypsum: Set retarder and strength accelerator. They opined while all fly ashes may not need additional gypsum, care has to be taken not to deprive those fly ashes in need of additional gypsum FaL-G technology, developed by the authors, achieved its breakthrough by tapping the potential of calcium aluminates towards the formation of ettringite and mono-sulphate; thus changing the pace of lime-fly ash chemistry. They said gypsum plays a predominant role as the strength accelerator in the context of hydrated mineralogy in FaL-G. Moreover, gypsum works as set-accelerator in lime-pozzolana binders in contrast to its role as set-retarder in OPC. Stefania Grzeszczyk, and Katarzyna Front; 2000.

They presented leaching test results of a class F low lime fly ash stabilized with varying percentages of lime (4, 6, and 10%) alone or in combination with gypsum (0. 5 and 1. 0%).. The effects of factors like lime content, gypsum content, curing period, and flow period on leaching of lime from a compacted stabilized fly ash matrix are reported herein. Two non dimensional parameters, alpha sub coi and beta sub coi, are presented herein to study the effect of gypsum on the total amount of calcium leached out from the compacted stabilized fly ash. They presented a model is also to estimate the amount of calcium leached out from the stabilized fly ash.

Several key parameters—such as treatment temperature, duration of process, and amount of chemical activator—are evaluated critically. The results confirm that fly ash can be solidified and specimens show splitting tensile strengths of about 1. 0  MPa by hydrothermal hot pressing alone. With a small amount of chemical activator (NaOH), the tensile strength can reach as highas5. 4  MPa. Fal-g used as Road sub base parameters Weiguo ShenMingkai Zhoua and Qinglin Zhao; 2006:, Studied on lime–fly ash–phosphogypsum, FaL-g Binder. As per his their study a new type of lime–fly ash–phosphogypsum binder was prepared. To improve the performances of lime–fly ash binder this was a typical semi-rigid road base Material binder in China.

As per, Degirmenci Nurhayat; 2008, they investigated Utilization of phosphogypsum as raw and calcined material in manufacturing of building products. The main objective of this research was to investigate the utilization potential of phosphogypsum with fly ash and lime in construction industry. On the basis of the test results, it was concluded that the curing conditions have an important influence on the compressive and flexural strength of the binder specimens. It was also concluded that the, Cementitous binder obtained can be used for the production of interior wall materials such as bricks and blocks MinYang et al; 2008: presented a (Technical Note) regarding activation of fly ash-lime systems using calcined phosphogypsum. Experiments were performed to determine the effect of calcined phosphogypsum on the strength of fly ash lime binders. But lowering the lime to calcined phosphogypsum ratio of blends with the same fly ash content yielded a relatively lower compressive development at late ages. Strengths of samples cured first at 45[degrees] C in over 90% R. H. for 12 h and then at room temperature were better than those cured at room temperature all the time. X-ray analysis suggests that the activation of calcined phosphogypsum to the systems was due to the formation of ettringite and dehydrate calcium sulfate during the hydration process.

The present study was focused on autoclaved PG and its use in making load-bearing wall bricks. Tobermorite was the significant hydrated product, which contributed to the strength of bricks. The use of autoclaved PG for making load-bearing wall bricks was recommended instead of conventional burnt clay bricks. A possibility to get water-stable materials at curing in the ambient air. It was shown that water uptake might be reduced by different methods, the best of which is short-term impregnation by a hydrophobic liquid of the siloxane group. Results from experiments with small specimens and full size pressed blocks were compared. It is noted that blocks answered to the requirements of Israeli Standard to cement concrete blocks. As per the S. Marinkovic and A. Kostic-Pulek; 2007. Examination of the system fly ash–lime–calcined gypsum–water. The feasibility of the utilization of the system fly ash–lime–calcined gypsum (? -hemihydrates)–water (the mass ratio 2:1:2:2. 5) for the production of building ceramics was investigated. S. Marinkovic and A. Kostic-Pulek opined curing of these products, a compressive strength of 4. 01  MPa in the water-cured and 7. 83  MPa in air-cured system developed. When the air-cured system was exposed to three alternate heating–cooling or three alternate cooling–heating cycles, the compressive strength increased (from 7. 83 to 9. 47 and 10. 55  MPa, respectively). The fly ash–lime–calcined gypsum–water systems prepared in this work can be applied for the manufacture of products for internal walls (bricks and blocks). As per Vimal Chandra Pandey Nandita Singh; 2010, systems Studies revealed that the lower FA incorporation in soil modifies the physico-chemical, biological and nutritional quality of the soil. He concluded that FA could be effectively used in the barren or sterile soil for improving quality and enhancing fertility. The purpose of this paper is to explore the possibility of FA addition into degraded soils for improving nutritional and physico-chemical properties. As per literature review of   Gourav, K  2010; fly ash-lime-gypsum (FALG) mixtures as intended to manufacture bricks or blocks for masonry applications indicates several gaps in understanding the various aspects of the technology. The literature review on the present thesis is an attempt to understand the behavior of compacted stabilized fly ash mixtures for the manufacture of fly ash bricks and characteristics of masonry using such bricks. A brief introduction to the technology of compacted stabilised fly ash bricks for structural masonry is provided. Review of the literature on fly ash-lime and fly ash-lime-gypsum mixtures, and fly ash bricks are provided in chapter 1The main focus of the investigations is on arriving at the optimum stabilizer-fly ash mixtures considering density, stabilizer-fly ash ratio, curing conditions, etc. as the variables. Some of the major conclusions of the investigations are (a) compressive strength of compacted stabilised fly ash mixtures is sensitive to dry density of the specimens and the strength increases with increase in density irrespective of stabilizer content and type of curing, (b) Optimum lime fly ash ratio yielding maximum strength is 0. 5, (c) addition of gypsum accelerates rate of strength gain for compacted fly ash-lime mixtures (d) for 28 days wet burlap curing optimum gypsum content yielding maximum strength is 2% and maximum compressive strength is achieved for lime contents in the range of 10 – 17%, (e) steam curing (at 80  °C for 24 hours) gives highest compressive strengt h for compacted fly ash-lime mixtures. Compressive strength, flexure bond strength and stress strain relationship for the fly ash brick masonry using cement-lime mortars were evaluated. The investigations clearly show the possibility of producing bricks of good quality using compacted fly ash-lime gypsum mixtures. Wet compressive strengths of 8- 10 MPa was obtained for compacted fly ash-lime-gypsum bricks at the age of 28 days. Wet strength to dry strength ratio for these bricks is in the range of 0. 55 – 0. 67. There is a large scope for selecting optimum mix ratios of fly ash, sand, lime and other additives to obtain a specific designed strength for the brick. Curing effect; on improving strength of fal-g. As per, Is? k Yilmaz and Berrin Civelekoglu; 2009, this paper deals with the performance of the gypsum as an additive for treatment of the expansive clay soils by means of swell potential and strength. Gypsum can be used as a stabilizing agent for expansive clay soils, effectively. The literature contains a vast number of stabilizing techniques such as lime, cement, and fly-ash for treatment of expansive clay soils. They however concluded the use of gypsum as a stabilizing agent is currently not clear. As per Pimraksa and P. Chindaprasirt; 2008, Water content, pre-curing period, lime content, gypsum content and calcined temperature are the factors investigated. The nature of hydration products and morphological characteristics of the lightweight bricks are also investigated. He concluded that the diatomaceous earth possesses pozzolanic property and can be used for making lightweight bricks. Concrete blocks of fal-g As per the literature review of Sunil Kumar. 2007, The compressive strength, water absorption and weight of FaL-G hollow blocks were determined . FaL-G hollow blocks are light in weight and being hollow, impart thermal insulation to the buildings. In this paper, a study based on the results of an experimental investigation on FaL-G hollow blocks is presented. The durability of these blocks in terms of loss in compressive strength in sulfate environments is also presented in this paper. It is observed that FaL-G hollow blocks have sufficient strength for their use in general building construction. High Volume Fly Ash Concrete and Its Mechanism Posted: 2009: As the fly ash emissions from industrial by-products is very large, large volume fly ash concrete to fully exploit the potential activity of industrial waste fly ash to reduce the amount of cement, concrete to reduce the Cost of production; to improve concrete workability, durability, and physical and mechanical properties. High Volume Fly Ash Concrete to save both cement, but also consume a large amount of fly ash, for the reduction of Environmental load of very effective. High Volume Fly Ash Concrete as a new type of material has its own unique advantages, with its performance study, large volume fly ash concrete and continuously improves the performance. In one embodiment the invention provides solid bricks produced by compressing together fly ash, bottom ash, gypsum, calcium carbonate, and lime. These bricks have sufficient structural strength for use in building and construction. In another embodiment, waste materials are encapsulated in a mixture of fly ash, bottom ash, gypsum, lime, and calcium carbonate and compressed into bricks that may be disposed of in an environmentally acceptable manner. Further, the compressed bricks containing waste material may be coated with an impermeable membrane of a synthetic polymeric material. Further, the invention provides a mobile, trailer-mounted apparatus for compressing the mixtures into bricks. As per the Technical paper ECO-FRIENDLY BUILDING MATERIALS AND TECHNOLOGIES. 2009. Fly ash-lime-gypsum bricks / blocks are very good products, giving the highest strength among various bricks. These require relatively higher investment and expensive raw materials to give arrange of high strength products. This is most suitable for mechanized operations, though semi mechanized operations are also possible. Fly ash lime gypsum bricks are made up of 60% fly ash, 10-20% lime and 10-20% gypsum. These bricks have medium range strength. Minimum compressive strength (28 days) of 70 kg/cm2 can easily be achieved and this can go up to 250 Kg/cm2 (in autoclaved type). Advantage of these bricks over burnt clay bricks: Lower requirement of mortar in construction, Plastering over brick can be avoided, Controlled dimensions, edges, smooth and fine finish can be in different colors using pigments and cost effective, energy-efficient environment friendly

Fords Advertising Strategy in India Research Paper

Fords Advertising Strategy in India - Research Paper Example The Indian economy is growing at a rate of 10% since the last 5 years (Uppal, et al, 2009). Apart from the growing middle class, India also features a strong upper class leading it to the fourth largest country with the highest number of billionaires. This makes India a lucrative market for high-end and premium brands as well. Besides being on the road of economic improvement, India also is a democratic state which encourages foreign direct investment. After a long isolation from international trade, India finally has opened its gates for foreign brands which leave a huge opportunity of the international giant corporations to capture their share of the market (Uppal, et al, 2009). As mentioned above, the high income earners of the country along with the growing middle class constitutes a high overall spending power and this fact makes it one of the most lucrative markets in South Asia and the whole world. In contrast to having a strong appeal to international businesses, India does h ave some factors which put a negative impact on its business environment. One of the problems which India faces is unimpressive law enforcement by the Indian judiciary. This is prevalent predominantly because of resource limitations and long procedures fashioned by corruption. However, in order to keep the consumers safe and to increase their confidence, exclusive courts catering to consumer needs and concerns have begun to be set up (Uppal et al, 2009). The elements which Ford must take care of while designing and executing its advertisements is the target segment which must targeted. As mentioned above, India has a growing economy with majority of a middle class and a high proportion of youth, the brands must be appropriately positioned in order to get the most business out of a segment. This means that a premium brand for example Mustang must not be positioned amongst the middle class as it will not be feasible for the company in terms of revenue. Therefore, considering the busin ess environment of India, the advertisements must have relevance to the lifestyle of the market. This suggests that if the target market does not drink, the advertisement must not show any reference to drinking otherwise, the brand will not have any receptive and relevance to the target market. Besides this, the idea of an advertisement must be in line with the culture and expectations of the audience. In order to be generally acceptable and receptive to the audience, the advertisement must clearly portray the true depiction of the lifestyle of the target market. Be it the fashion, models, lifestyle, language etc, every element of the ad must have a relevance to the target market else the brand will not be accepted and will not sell. 2. India’s Advertising Industry India’s advertising industry is on the boom. From being a small scale business to a fully fledged industry, the Indian advertisement has become a world in itself. It is now considered as one of the major ind ustries of the tertiary sector of India with worth $6.4 billion. Apart from the traditional print and electronic media, the advertising industry of India is registering enormous growth of the social media. The internet is increasingly becoming an important tool for businesses to sell their product and for the advertisers to market their brands. The fact that the internet has become a marketplace itself has been well adopted by the Indian adverti
