Abstract

With the considerations of fiber volume fraction, matrix strength concrete and steel fiber type, the standard sample of 150 mm×150 mm×150 mm cube was used to conduct compressive and splitting tensile tests and the effects of parameters on tensioncompression ratio of concrete were analyzed. The results show that steel fiber can increase the compressive and splitting tensile strengths of concrete ,and the concrete compression and tensile failure modes are significantly improved with good integrity. Steel fiber can enhance the tensioncompression ratio of concrete, and the ratio is increased with the increasing of steel fiber volume fraction with the largest increasing amplitude of 27.4%. The ratio of tensioncompression is decreased with the increasing of matrix strength, and the decreasing amplitude is obviously reduced than ordinary concrete. Corrugated steel fiber and end hook type steel fiber can both improve the tensioncompression ratio of concrete,and corrugated steel fiber is superior to end hook.The improving effect of screw type steel fiber is the worst with reduced concrete tensioncompression ratio.

Key words
