Experimental Study on Strength behavior of Concrete with partial replacement of Cement with Silica fume and Coarse aggregate with waste Tire Rubber: A Review

Abstract

A very large amount of waste rubber tire are being generated each year all around the world. Being nonbiodegradable in nature their recycling is not easy. On burning they produce very toxic and harmful smoke. So the only option is to dump them to landfills. It is also not a proper solution as it takes a lot of space and stockpiles of waste rubber leads to soil pollution and contaminate water bodies along with ground water. Statistics show that every year more than 500 million tires are discarded to landfills, and the estimation is about 5000 million tires would be discarded by 2030. Many research studies has shown that the waste rubber tires could be used in concrete. Concrete with rubber tire has shown reduction in compressive and flexural tensile strength but they do possess some positive aspects as they have better toughness, impact resistance, thermal and sound properties. This paper presents a literature review on using waste rubber tire in concrete as a partial replacement of cement, coarse or fine aggregates.
