In the present scenario in the construction industry, use of economic and environmental friendly material is of a great concern. One of the main ingredients used is cement. It is observed from various studies that the heat emitted from cement accounts to a greater percentage in global warming. Cement industries account to a greater emission of CO2 and they also use high levels of energy resources in the production of cement. In order to minimize these effects, replacement of cement with some pozzolanic materials such as fly ash, can have an improving effect against these harmful factors. In this work, identified the optimum mix of fly ash (major ingredients) generated at Barapukuria Thermal Power Plant, sand, hydrated lime and gypsum and also optimized the brick forming pressure. Fly ash- 55%, sand- 30% and hydrated lime – 15% with gypsum14% was found to be the optimum mix. For the optimum mix studied the compressive strength, microstructure, shrinkage property, unit volume weight, Initial rate of absorption, absorption capacity, apparent porosity, open pore and impervious pore of the fly ash–sand–lime-gypsum bricks produced with optimized composition under various brick forming pressures, Efflorescence and radio activity of the bricks formed under optimized conditions were also investigated1 . In this paper, experimentally investigated the fly ash brick mix proportions by Taguchi method. Least quantity of cement and fly ash has been used as binding materials and considered the control factor as water binder ratio. Both. So the effects of water/binder ratio, fly ash, coarse sand, and stone dust on the performance characteristics are analyzed using signal-to-noise ratios and mean response data. Furthermore, the estimated optimum values of the process parameters are corresponding to water/binder ratio of 0.4, fly ash of 39%, coarse sand of 24%, and stone dust of 30%2 . The addition of flyash up to 60% at a fixing temperature as 950ºc has no siginificant harmful effects on the brick quality.It seems that the fly ash added building bricks show reasonably good properties and may become competitive with the conventional building bricks. Use of fly ash as a raw material for the production of building bricks is not only viable alternative to clay but also a solution to difficult and expensive waste disposal problem3 . In the present work the attempt has made to find the optimum mix percentage of to obtain maximum compressive strength of flyash brick admixed with lime, gypsum and quarry dust at various proportions

We offer pure and flawlessly white Chetak plaster of paris ( POP ). The whiteness of this plaster of paris ( POP ) stays for years together thus proving the fact that it's purity is not momentary but a long lasting one. Chetak is a superior quality plaster of paris ( POP ) as its manufacturing process includes many strong scientific tests. The major test is the calcium cooking process wherein each droplet of pure calcium sulphate is boiled at a predetermined temperature and the silica is separated. The result of this procedure is that Chetak doesn't shrink or crack after drying thus our plaster of plaster is very user friendly and doesn't create much problems for the user.
