Abstract—The steel fiber reinforced concrete(SFRC) shows better performance under blast and impact loading than conventional concrete in virtue of its better ductility. The mixture proportions of SFRC were designed with the content of steel fibers varied from 0 to 1.5%. The compressive and tensile strength were investigated using Ф50×100mm and Ф70×30mm specimens respectively, and SHPB tests were performed using Ф70×36cm. The results of experiments show that the compressive strength and the splitting strength gradually increased with the increase of steel fibre content, and the tensile property significantly increases more enhanced than the former; SFRC is a material with obvious strain-rate effect，and the shape of the dynamic stress-strain curve is basically the same; The formulae of SFRC's DIF are obtained by fitting the test results would provide a good reference for actual engineering calculation, which may benefits to the science and engineering design.
