In India, bricks are mainly composed up of clay, and are generally produced in traditional, unorganizedsmall scale industries. Bricks are important building material and about 250 billion bricks are annually produced by thebrick industries. Red clay bricks making consumes larger amount of clay which leads to top soil removal and landdegradation. Large areas of lands are destroyed every year especially in developing countries due to collection of soilfrom a depth of about 1 to 2 m from agricultural land. An important step in brick making is firing of bricks in brick kilnswhich cause serious environmental pollution and health problems. Brick burning largely influence the concentrations ofgreenhouse gases in the atmosphere. This causes serious air pollution and also workers in brick industries are prone torespiratory diseases, to avoid all this environmental threats brick made of waste that is originated from the waste as aresidue from the different industries and factories, this types of bricks is termed as fly ash bricks which is composed bythe different materials such as lime, gypsum, sand, fly ash etc. The objective of this paper is to explain aboutmanufacturing of fly ash bricks in present era and advantages of using it as a construction material. In this paper authorexplain about advantages of fly ash bricks over burnt clay bricks or red bricks and manufacturing process of fly ashbrick.
