Experimental Study on Partially Replacement of Coarse Aggregate by Using Rubber

Now a days, rubber is produced excessively worldwide every year. It cannot be discharge off easily in the environment as its decomposition takes much time and also produces environmental pollution. In such a case the reuse of rubber would be a better choice. In order to reuse rubber wastes, it was added to concrete as coarse aggregate and its different properties like compressive strength, tensile strength, ductility etc. were investigated and compared with ordinary concrete. As a result it was found that rubberized concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. The compressive strength of rubberized concrete can be increased by adding some amount of silica to it. The recycled rubber tire waste is a promising material in the construction industry and the sole reason for this is the lightweight of the resulting concrete. When the rubber tire is incorporated in it as an aggregate replacement.
