Steel slag powders were compared with cement in terms of chemical and mineral compositions. Then, steel slag powders with chemical compositions similar to cement and physico-mechanical properties meeting requirements were used as active components to completely replace cement to design mix proportions of reactive powder concrete (RPC) containing steel slag powders. According to the preparation principle of RPC, the benchmark mix proportions were proposed. By studying influences of various compositions of RPC containing steel slag powders on the properties and changes in the properties, the reasonable mix proportions of various compositions of RPC containing steel slag powders were obtained. The research provides important reference for the preparation and application of RPC in which cement is replaced with steel slag powders.
