Sustainable development mainly aims to reduce the negative environmental impact caused by construction sector which is the largest consumer of the natural resources. Over a period of time, the waste management has become one of the most complex and challenging problem that we have to face. Day after day many new innovations and developments advancing in construction sector, the usage of natural aggregate is in high demand and at the same time production of solid wastes from the demolitions of constructions is also gradually increasing. Because of these reasons, the reuse of demolished construction wastes and granite powder came into the picture as a way to reduce the solid wastes and to minimize the scarcity of natural aggregates. Crushed waste tiles and granite powder helps to achieve our goal to reduce the demand on natural aggregates. So Crushed waste tiles and granite powder are introduced as a replacement for the coarse aggregates and fine aggregates. The waste crushed tiles were used as coarse aggregatesâ replacement by 10%, 20% and 30% and granite powder were replaced in place of fine aggregate by 10%, 20% and 30% without any change the mix design. M20 grade of concrete was designed to prepare the conventional mix. Different types of samples were prepared by replacing the coarse aggregate and fine aggregates with crushed tiles and granite powder at different percentage. We use cement instead of silica fume with a percentage of 10%. Experimental investigation like compressive strength test, split tensile strength test were tested. Different concrete mixes with different percentage of waste crushed tiles and granite powder after 7, 14 and 28 days curing period, it is observed that strength increases on replacement of Ceramic tile.
