Abstract
This article has carried on the silicon ash content under the condition of 10%, and different rubber particle size and different dosage of silica fume rubber modified cement concrete in all kinds of performance testing, such as: the experiment research on compressive strength, splitting tensile strength, flexural strength and strong noise reduction performance. Experimental results show that silica fume can help improve the compression, splitting and flexural strength of rubber concrete, ratio of fracture and pressure and ratio of tension and compression of concrete are improved greatly after adding silica fume;With the increase of rubber particles, dynamic modulus of concrete decreased, noise reduction effect of silica fume concrete is significantly modified .
