PERFORMANCE ENHANCEMENT OF CONCRETE BY REPLACING COARSE AGGREGETE WITH TYRE RUBBER: A STUDY

M. Harikaran and N. Balasundaram

Abstract

The search for a new and viable alternative is important for protection of innate resources and reduction in manufacturing cost. Steel slag, coconut shell and over burnt brick have already been tested and used as alternative materials for coarse aggregate. The desolate tyre rubber is aassured material in the building industries as part of coarse aggregate replaced due to its light weight, energy absorption, elasticity and heat insulating properties. This has the other advantage of saving in innate aggregate consumed in the creating of concrete and also this concrete will be light in weight. In this work, analysis has been executed to appraise this tire rubber as supplementary coarse material and this will be beneficial for future application for innate aggregate in concrete. This study reports split stretchy strength, compressive strength and flexural strength variation in concrete with 5%, 10%, 15%, and 20% replacement of coarse aggregates by waste tyre rubber.
