An Experimental Investigation on Concrete as a Partial Replacement of Ca and Fa with Crushed Tiles and Granite Powder for M-30 Grade Concrete (Normal Water and Sea Water Condition)

As all known concrete is a versatile engineering composite material made with cement, aggregates and admixtures. Due to the day by day innovations and development in construction field, the use of natural aggregates is very high and at the same time production of solid wastes from the demolitions of constructions is also very high. And also there is a scarcity of natural aggregates because of extensive use of concrete. Because of these reasons the reuse of demolished constructional wastes and granite powder came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates. Crushed tiles and Granite powder are used as a replacement to the coarse aggregates and fine aggregate. The combustion of waste crushed tiles were replaced in place of coarse aggregates by 0%, 5%, 10%, 15% and 20% and Granite powder were replaced in place of fine aggregate by 0%, 5%, 10%,15% and 20% without changing the mix design. M30 grade of concrete was designed to prepare the conventional mix. Without changing the mix design different types of mixes were prepared by replacing the coarse aggregates and fine aggregate at different percentages of crushed tiles and granite powder. These admixtures are used in both normal conditions and sea shore conditions. Experimental investigation like Compressive strength test & Split tensile strength tests conducted for different concrete mixes with different percentages of waste crushed tiles and granite powder after 7 and 28 days curing period(Normal water and Sea water). M30 grade of concrete was designed to prepare the conventional mix. Without changing the mix design total 5 types of mixes were prepared by replacing the fine and coarse aggregates at different percentages of granite powder and crushed tiles. Variations in the workability for these different mixes were studied and observed that, increase in the percentage of replacement of granite powder and crushed tiles.
