摘要：

Fly ash can improve the physical and mechanical properties of the magnesium phosphate cement (IVIPC) paste. The influence of fly ash on the strength, the mortar fluidity, the durability and the setting time of M PC paste were studied in this paper. The results show that: The function of fly ash to the MPC is as followed: physical fill, superplastic and chemical reactions; the optimal content of fly ash is about 30% by weight, and M PC with 30% fly ash has excellent mechanical property and high fluidity; the fineness of magnesia affected the mechanical properties of MPC.
