摘要 配制了由减水剂、盐类组成的NY 2复合激发剂 ,并将其掺入由 42 5R水泥和粘土混合而成的火山灰水泥中。实验结果表明 ,当粘土掺量为 30 %时 ,掺加 0 .8%~ 1.2 %的NY 2复合激发剂 ,可以在提高水泥早、后期强度的同时 ,改善水泥流动性 ,调整水泥凝结时间并保持火山灰水泥的其他特性。 A new composite stimulator composed of water reducer and saltsare was prepared by the experimental studies. This simulator is added into the pozzolana cement blended with clay. The experimental results show that adding NY\|2 composite stimulator by weight of 0.8%~1.2% cement can enhance cement strength in early and late stages of cement hardening, improve cement fluidity and adjust hardening time, as well as keep other good properties. Application shows that this composite stimulator can bring large profit.
