Abstract：The composite cement was prepared by calcined shale and silicate.Through testing the physical properties of the composite cement,the optimal ratio of raw materials was obtained based on the orthogonal test and analysis.The hydration mechanism was discussed.The results show that the composite cement consisted calcined shale,slag and fly ash in an apporpriate ratio can reach the desired stability,setting time and mechanical strength of P.C 42.5#cement.
Keywords：calcined shale;composite cement;hydration mechanism
