Experimental Study on the Mechanical Properties of the Crumb Rubber Concrete

Article Preview

Abstract:

The mechanical properties of concrete with composition of scrapped rubber tyre crumb replacing part of the fine aggregates were investigated. The testing method of the mechanical properties was executed according to . Many groups of crumb rubber concrete specimens are manufactured in different kinds of size and amount of rubber chips. The powder rubber and crumb rubber were mixed into C35 plain concrete, by the volume rations of 0%, 20%, 40 %, 60%, 80% and 100% of the fine aggregates, to investigate the influence of size and amount of rubber chips on the mechanical properties. The results of test indicate: the cubic compression strength, the tensile splitting strength and the strength of rupture decreased with the increase of rubber admixture. But there are some remarkable properties which is difficult to attain on ordinary concrete, such as better cracking resistance, better deformation property, minor density and so on.
