To Study the Strength Characteristics of Concrete using Combination of Tyre Rubber and Recycled Aggregate

In recent decades, worldwide growth of automobile industry and increasing use of car as a means of transport has tremendously boosted tire production. This has generated massive stockpiles of used tires. Big amounts of used rubber tires accumulate in the world each year-275 million in the United States and 180 million in European Union. India is presently generating construction and demolition waste to the tune of23.75 million tones annually and these figures are likely to double fold in the next 7years.This project is an attempt to design concrete of 25Mpa using natural sand, Conventional sand, Shredded rubber, crumb rubber and recycled aggregate as an alternative source of aggregate in concrete. A comparison with control mix which uses conventional material will allow to assess the difference in the properties of materials or concrete and ultimately the suitability of using shredded rubber, crumb rubber aggregate and recycled aggregate in concrete (probably in percentages) for structural components. Replacement of constant 1% crumb rubber, 1% shredded rubber and variable as 10%, 20%, 30%, 40% replacement of recycled aggregate respectively. By above mix design, investigate the properties of compressive strength, split tensile strength.
