Bricks are a commonly used building material all over the world for constructing walls, pavement and other elements in masonry construction. Conventional bricks are manufactured by firing of clay in high temperature kilns. Extensive research is going on production of bricks from industrial wastes as there is a shortage of natural resources that are used as raw materials for the manufacturing of bricks. This paper presents an experimental study carried out on bricks made from fly ash, Ground Granulated Blast furnace Slag (GGBS) and Manufactured Sand (M-sand). This investigation also aims to use waste materials effectively since fly ash is a waste obtained from thermal power plants and GGBS is a waste from steel plant. The properties of the fly ash bricks are investigated by conducting various tests like Compressive strength test, water absorption test and test for dimensional tolerance as per relevant Indian Standards.
