摘　　要：研究了复合激发剂复掺对掺30%和50%粉煤灰复合水泥性能的影响.试验结果表明:复合激发不仅可以提高掺30%,50%粉煤灰的水泥硬化浆体的早期强度,而且提高了后期的强度;正交实验优化的30%和50%粉煤灰复合硅酸盐水泥复合激发剂的添加量分别为:1%Na2SO4,1%CaSO4,1%Na2SiO3和1%Na2SO4,4%CaSO4,1.5%Na2SiO3.复合激发剂中各组分发挥了各自的激发作用,复合水泥性能满足国家标准.The influence of compound activators on the properties of composite cement containing 30% and 50% fly ash were studied.The experiential results indicate that compound activator can increase the early strength of,and that it can increase the later strength.The optimization content of compound activators were 1%Na2SO4,1%CaSO4,1%Na2SiO3 for 30% and 1%Na2SO4,4%CaS04,1.5%Na2SiO3 for 50% fly ash composite cement.Each component in compound activators can play its effect on activation.The properties of composite cement can meet to the national standard.
