For a long time, some concrete structures usually can not be used because of lacking resistance of impact, such as different kinds of silo structure, pavement concrete, deck concrete, railroad tie, shaft, ore drop shaft as well as national defence establishment. It is important to master concrete mobile load performance for design structure received impact load.The properties and present condition of RPC is discussed in this paper, also the influence of impact resistance of RPC in different ratio is researched. Elaborating Strengthening theories of fiber is introduced in the paper. In a certain amount of gravel, the impact resistance in different amount of steel fiber is researched, as to find a optical ratio of steel fiber and gravel and then put it into practice. In the range of the experiment, the impact resistance of concrete is increasing with the quantity of steel fiber increasing, and decreasing with the quantity of gravel increasingThrough comparison, the influence of impact resistance in different factors is confirmed, the optimum ratio is found, and the theory of impact resistance is analysed. Experiment research shows that fiber is efficient means to enhance the impact resistance of concrete. Finally, the application prospect of gravel RPC is prospected.
