In this paper, a total of 150 specimens were fabricated with rubber particles volume substation of sand (0~20%) and steel fiber volume fraction (0~1.5%). The cube and axial compression test, splitting tensile test, bending test, double-shear test were performed to investigate their mechanical properties of steel fiber reinforced rubberized concrete (SF-R/C), and the microstructure and interface of SF-R/C were investigated by scanning electron microscopy (SEM). The results show that adding rubber particles and steel fiber can significantly reduce the workability. With the increase of rubber content, each test of SF-R/C strength decreases. Different from rubber concrete, the failure mode of SF-R/C specimens is ductile. After adding steel fiber, SF-R/C strengths increase in varying degree, especially in shear strength. The shear strength is enhanced by 78% with a steel fiber content of 1.5% and a rubber particles content of 10%. Based on experimental data and comprehensively considering the influence of rubber particles and steel fibers, the calculation formula of strength indexes of SF-R/C are put forward and the interrelations among the strength indexes of SF-R/C are obtained.
