Test results show that the steel fiber in concrete have more effectiveness on improving the splitting tensile strength and the flexural strength in the early age than after its hardening ; the flexural modulus of elasticity of sfrc are higher than the plain concrete at different ages while their compressive modulus of elasticity are almost the same. it ' s also shown that, similar to the plain concrete, the early - age loading decreases the strengths of sfrc, but, with the increase of the contents of the steel fiber things are getting better, especially for the splitting tensile strength and the flexural strength
