Based on previous and theoretical study, with raw materials of ordinary Portland cement, slag, silica fume, superplasticizer and standard sand, an experimental research on proportion of reactive powder concrete, was carried out in this paper. In order to obtain a reasonable concrete mixture ratio, several groups of specimens were tested. The effects of water_binder ratio, sand_binder ratio, quantity of admixture and content of steel fiber on compressive and bending strength of RPC were concerned. Under the premise of ensuring the fine quality of reactive powder concrete, the possibility of getting a concrete mixture ratio was explored by using the materails which are easily approached.
