Abstract

The growing amount of rubber-shredded waste from tires causes environmental problems. This research aimed to analyze the application of shredded rubber in the concrete mixtures. Laboratory tests were carried out on 15 cylinders and 15 beams of concrete specimens that contained shredded rubber. Compressive strength, flexural strength, and modulus of elasticity measurements were performed using test specimen containing 400 kg/m3of cement and varied volume ratio of shredded rubber to sand which were 0%: 100%; 10%: 90%; 20%: 80%; 30%: 70%; and 40%: 60%. The results show that the mechanical properties of concrete decreased by 50% after the addition of shredded rubber in the mix by 40%. However, the same volumetric ratio of sand and shredded rubber increased the concrete ductility. The use of 20% shredded rubber in the concrete mix can produce light weight concrete for structural construction.
