Experimental Study in Strength of Concrete by using Waste Tyre Rubber as Partial Replacement of Coarse Aggregate

Modifications of construction materials have an important bearing on the building sector. Several attempts have been therefore made in the building material industry to put to use waste material products, e.g., worn-out tyres, into useful and cos effective items. This Waste - Tyre rubber is the significant environmental problems worldwide. With the increase in the automobile production, large amounts of waste tyre need to be disposed. Due the rapid depletion of available sites for waste disposal, many countries banned the disposal of waste tyre rubber in landfills. Research had been in progress for long time to find alternatives to the waste tyre disposal. Among these alternatives is the recycling of waste-tyre rubber. Recycled waste tyre rubber is a most widely used method. Recycle wasted Tyre Rubber is a promising material in the construction industry due to its light weight, elasticity energy absorption, sound and heat insulating properties. Success in this regard will contribute to the reduction of waste material dumping problems by utilizing the waste materials as raw material for other products. The present proposal involves a comprehensive laboratory study for the newer application of this waste material in the preparation of fibrous concrete. The primary objective of investigation is to study the strength behaviour i.e. compressive and flexural strength, of rubberized concrete with different volume of waste- Tyre rubber. Parameter to be varied in Investigation: I. Volume variation of waste rubber. In this the density and compressive strength of concrete utilizing waste tyre rubber has been investigated. The proposed work is aimed to study the effect of volume variation of waste-Tyre rubber on the compressive strength, flexural strength, Slump test & the relationship between stress and strain of the concrete. Recycled waste tyre rubber has been used in this study to replace the coarse aggregate by weight of 15%. The results shows that although, there was a significant reduction in the compressive strength of concrete utilizing waste tyre rubber than normal concrete, concrete utilizing waste tyre rubber demonstrated a ductile, plastic failure rather than brittle failure. In this study we use to find out the compressive strength &flexural strength of concrete by the replacement of coarse aggregate by waste-Tyre rubber in normal concrete in grade of M30.
