The Research on Bond Property of Rubber Concrete

Article Preview

Abstract:

In order to realize the recycle of waste tires, rubber concrete can be utilized in road engineering. The bond property of interface between rubber concrete and matrix ordinary concrete is one of the key factors. This paper studied the interfacial bond property by splitting tensile strength test and shear strength test and considered several influence factors, such as rubber volume fraction, rubber particle size, interfacial roughness and curing time of matrix concrete. The results show that the shear strength decreases with the increase of rubber content, longer curing time of matrix concrete, and the larger size of rubber particle. The splitting tensile strength also deceases with the longer curing time of matrix concrete or smaller interfacial roughness. However, no regular relationship is found between the splitting tensile strength and the size of rubber particle or rubber volume content.
