An Experimental Study on Partial Replacement of Coarse Aggregate with Mangalore Tiles in Self-Compacting Concrete

Abstract

In the world wide the usage of concrete is more in the construction industry which contains maximum volume of aggregates than cement due to this the natural aggregates are depleted day by day. In this project coarse aggregate is replaced with Mangalore tiles in self-compacting concrete ranging from 10%, 20%, 30%, 40%. Mangalore tiles are rejected tiles which are not in ideal size and shape. The various tests are carried out such as compressive strength, flexural strength and spilt tensile strength test at 7 and 28 days for cubes, cylinder and beams. Here the grade of the concrete is M50 and mix design is carried out. Mechanical properties, strength, durability and optimum percentage of crushed Mangalore tiles is observed. Self-compacting concrete is a concrete mix which has a low yield stress, good segregation resistance and moderate viscosity uniform suspension of solid particles during transportation and placement. Mangalore tiles waste is used as coarse aggregate for the present study which can be obtained in the rural areas where the major number of houses is built using these tiles for the roof. The demolition of these generates maximum roof tiles which will be wasted.
