Abstract

In the current paper, the relative dynamic modulus of elasticity, compressive strength, flexural strength and the concentration of chloride in rubber included concrete treated with water or composite salt solution were investigated. The mechanism of the degradation of rubber included concrete was briefly analyzed. The experimental results showed that rubber included concrete performed comparably with reference concrete when concretes were immersed in water or composite salt solution, however, under the action of wet-dry cycling, the properties of rubber included concrete was much inferior to that of reference concrete. Furthermore, the action of composite salt solution accelerated the degradation of rubber included concrete. It is therefore suggested that rubber included concrete should not be used where long-term wet-dry cycling, hot and dry weather occurs or where sulfate attack may happen.
