Abstract: The experiment of steer/ polypropylene hybrid fiber reinforced concrete slump and resistance to impact is carried out through orthogonal design. The results show that hybrid fiber is remarkable for resistance to impact of concrete, which reflects that different elastic modulus fiber is different for resistance to impact of concrete at different phase，and the optimum mix proportion under the specific condition is found for hybrid fiber reinforced concrete.
