Experimental Study on Durability of High Strength and High Performance Rubber Concrete

Abstract

The experimental researches the influence of rubber dosage to the frost resistance and impermeability of high strength and high performance concrete which different strength grades. The results show that the rubber will cause the loss of relative dynamic elastic modulus increase of high strength and high performance concrete, and the rubber content is greater ,the more loss of relative dynamic elastic modulus to the concrete. When the rubber content of 4%~8% can improve the impermeability of high strength and high performance concrete, the increase of dosage of rubber will weaken the impermeability of concrete.
