The disposal of industrial wastes comprises one of the major worldwide environmental problems as these wastes render the environment unfriendly. The growing demand for waste utilization has made solid wastes- like materials from granite processing industry, and sand to be absorbed into the ceramic composition of bricks. The possibility of reduction in production costs provides a strong logic for use of these wastes. In this work, attempt was made to develop acid resistant bricks from quarry fine waste residues (stone dust, kaolin and sand). In order to investigate the possibility of producing acid resistant bricks, nine suggested batches, namely, A1, A2, A3, A4, A5, B1, B2, B3 and B4, were composed for this present study. These mixtures were composed of 40 wt% of Kaolin fine residue with 10-50 wt% of stone dust and silica sand; and 50 wt% of Kaolin fine residue with 10-40 wt% of stone dust and silica sand respectively. The bodies made with the variation of raw materials were sintered at 9700C and their behaviors with respect to apparent porosity, water absorption, bulk density, firing volume changes, compressive strength and acid resistance as a function of temperature, stone dust and sand was studied. It was observed that most of the developed brick samples showed excellent results in both HCl and H2SO4 media in accordance with IS: 4860-1968 and ESS:41-1986.
