The paper study affect of fly ash,slag powder,silica fume of cement properties. It is to play their respective advantages and complement each other's advantages about three factors. Finally,the highperformance of admixture that have a good working performance and mechanical properties be formulated. The results indicated that the ratio among fly ash,slag powder,silica fume is 5% ∶ 13% ∶ 7%. The admixture performance to the intensity determination and hydration analysis is improved obviously than the pure cement.
