摘　　要：研究了激发剂复掺对掺50%粉煤灰的水泥硬化浆体性能的影响。试验结果表明:复合激发不仅可以提高掺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;复合激发剂中各组分发挥了各自的激发作用,其激发效果比各自的单掺激发效果优。The influence of compound activator on the properties of harden paste with 50% fly ash was studied. The experiential results indicate that compound activator can increase the early strength of harden paste containing 50% fly ash, and that it can increase the later strength. Each component in compound activator can play its effect on activation, and the effect of compound activator is better than that of corresponding activator.
