Experimental Study of Crumb Rubber in Concrete

Crumb rubber is a material produced by shredding and commutating used tires. Waste tire dumping, disposal of these materials or burning these tires cause serious health and environmental problems. On the other side the traffic intensity also increasing day by day and thus bearing capacities also increased the long term goal of the work is to find a means to dispose of the crumb rubber in concrete and still provide a final product with good engineering properties. Due to the depletion of natural sand it is required to use other material than sand being used as the fine aggregate in concrete. The innovative use of the crumb rubber in concrete formulations as a sand replacement in range of 0%, 2.5%,5%,7.5% and 10 % by weight for M-25 grade cement (OPC). It will include an experimental review on the effects of CRM on compressive test and flexure test. KeywordsConcrete, Crumb Rubber, Water Absorption Test, Compressive Test, Flexure Test
