Study on Tension and Compression Ratio and Discount Ratio of Rubber Modified Silica Fume Concrete

Abstract

This paper conducted all kinds of performance testing of different rubber particle size and different dosage of silica fume rubber modified cement concrete under the condition of 10% the silicon ash content, such as: analysis research of compressive strength, splitting tensile strength, flexural strength, and pull off the pressure ratio and pressure ratio. Experimental results show that silica fume can improve rubber concrete compressive strength, splitting, bending strength, the folding ratio, adding silica fume concrete fracture pressure ratio and compression ratio are improved; the silica fume can effectively improve large brittleness and lack toughness of concrete, and improve the compactness of concrete.
