A STUDY ON PERFORMANCE OF CRUSHED TILES AS PARTIAL REPLACEMENT OF COARSE AGGREGATE AND EFFECT OF COIR FIBRE ON CRUSHED TILES MIXED CONCRETE

Concrete has several appealing characteristics that have made it as a widely used construction material. It is the material of choice where strength, performance, durability etc., are required and concrete is undoubtedly most versatile construction material. 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. Hence, there is a compulsion on the part of civil engineering community, to take appropriate strategies so that the consumption of such potential waste by the construction industries will be on rise day-by-day leading to a green environment which is of course the need of the hour for our nation. The waste crushed tiles were replaced in place of coarse aggregates by 10%, 20%, 30%, 40%, and 50% without changing the mix design. M20 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 at different percentages of crushed tiles. Experimental investigation like Compressive strength test, workability for different concrete mixes with different percentages of waste crushed after 7, 14 and 28days curing period. Variations in the workability and compressive strength and split tensile strength for these different mixes were studied and observed the optimum mix. For the optimum percentage of crushed tiles, Coir fibers from 0 to 2% with an interval of 0.5% .This paper deals with the experimental studies made on compressive strength, split tensile strength of concrete made with ceramic tiles and coir fibre.
