Experimental Study on Flexural Toughness of SFRC

摘要：

　　This paper introduces the test results of the flexural performance of CF40 steel fiber reinforced concrete (SFRC) designed by the binary superposition mix design method.The flexural strength and flexural load ~ deflection curves were got from the test SFRC specimens with the different fraction of steel fiber by volume and the different thickness of cement paste wrapping steel fibers.The effects of the fraction of steel fiber by volume and the thickness of cement paste on the flexural strength and toughness of SFRC are analyzed.It is demonstrated that the flexural toughness of SFRC increases with the increase of the fraction of steel fiber by volume,the reasonable thickness of cement paste wrapping steel fibers is 1.0mm.
