摘　　要：采用激发剂技术，研制成功了粉煤灰掺量达４０％～６０％，强度标号达４７．７～５２．９ＭＰａ的大掺量粉煤灰水泥。研究表明，这种水泥的标准稠度需水量、凝结时间、安定性等物理性能满足国家标准的有关要求，水泥石结构致密。By means of activator,a kind of Large Fly ash Content Cement was obtained,which fly ash content was 40%～60% and R 28 was up to 47.7 52.9MPa.The physical property such as normal consistency water demand,setting time and soundness of cement could meet the standard.The harden cement has lower porosity compared with normal Fly ash Portland Cement.
