Experimental Investigation on Scrap Tyre as Partial Replacement for Fine Aggregate in Concrete

Disposal of waste tires is becoming a major waste management problem in the world at the moment. Environmental concerns are also being raised against uncontrolled extraction of natural sand. In this scenario an attempt has been made to investigate the optimal use of waste tyre rubber crumbs as fine aggregate in concrete composite. A total of 85cubes, cylinders and beam specimens were cast with the replacement offine aggregate by shredded rubber crumbs with the proportion of 5,10, and 15% by weight and compared with 21 conventional specimens. Fresh and hardened properties of concrete such as workability, compressive strength, tensile strength and flexural strength were identified and finally it will suggest 10% replacement of waste tyre rubber aggregate with fine aggregate Will gives optimal and safest replacement in concrete composites
