Abstract: The general practice of recycling brick waste is to crush and use them as aggregates in concrete or low grade road base or sent directly for landfill. The author of the present study is of the opinion, that, such practices of brick waste utilization are really not sustainable, as, this inert waste can be utilized, to produce durable and attractive (in terms of color and texture) building units. With this premise, this experimental study is pursued to assess the potential of brick masonry waste for making Cement Stabilized Masonry Blocks (CSMB). The Brick Powder (BP) is obtained by crushing the brick masonry waste obtained from dump yards and used in conjunction with Natural Fine Aggregate (NFA). Fifteen mix compositions are considered by varying BP, NFA as 60:40, 70:30 and 80:20 respectively, with the percentage of cement content as 5, 8, 10, 12 and 15. Wet and dry compressive strength of each of the mix variants is determined by performing tests on cube specimens of size 70. 6mm.The wet compressive strength is found to be 0.75 times the dry compressive strength. A minimum of 10% of cement content is required to achieve the strength in excess of 3.5 Mpa.
