Experimental Investigation of concrete as a Partial Replacement of Fine Aggregate by Crushed Marble Stone and Coarse Aggregate by Crushed Tiles

Abstract: Many researchers have been currently going to modify and improved the concrete properties by the addition of different types of materials. This Experimental investigation represents the Optimum use of the crushed tiles and crushed marble stone with the concrete mixture and will help in achieving the desired results. Due to the day by day innovations and development in construction field, the use of crushed tiles is very high and at the same time production of solid wastes from the demolitions of constructions is also very high. Because of these reasons the reuse of demolished constructional wastes and crushed marble stone came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates. Crushed waste tiles and crushed marble stone 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%, 10%, 20%, 30%  and 40% and waste marble  were replaced in place of fine aggregate by 0%, 5%, 10%, 15%  and 20% without changing the mix design. The water cement ratio was kept constant at 0.45. M30 grade of concrete was designed to prepare the plain 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 crushed marble stone. Experimental investigation like abrasion value, crushing strength, Compressive strength test, Split tensile strength test, Flexural strength test, Water absorption test and Bond strength test for different concrete mixes with different percentages of waste crushed tiles and crushed marble stone after 7 and 28 days curing  period. Variations in the workability for these different mixes were studied and observed that, increase in the percentage of replacement of crushed marble stone and crushed tiles.
