摘要：

The composite cement of flyash and sulphatealuminium cement was studied by compressive strength XRD TG and SEM on the basis of induced crystallization effect particle effect and priming effect, etc. The results show that, after adding M, the compressive strength of 2 h, 3, 7 and 28 d have improved 140%, 116%, 80% and 60% respectively; more AFt and alumina gel are produced in early age and samples become more compactness; early phase crystalline forms of AFt may get poor; with the prolong of hydration time, crystalline forms of AFt improves, flyash participates in the send hydration reaction and is tightly binded by its hydration products, the system gets more compactness, so the long-term strength increases. ©, 2015, Journal of Functional Materials.
