摘　　要：采用激发剂技术，研制成功了煤矸石掺量达６０％，强度标号达４９．６ＭＰａ的大掺量煤矸石水泥．研究表明，这种水泥的标准稠度需水量、凝结时间、安定性等物理性能符合国家标准的有关要求；水泥石孔隙率为０．０４１３ｃｍ３·ｇ－１，结构致密；７ｄ水化热为２３５ｋＪ·ｋｇ－１，属低热水泥．By means of activator,a kind of large gangue content cement was obtained,which gangue content is 60% and R 28 is up to 49.6MPa.The physical property such as normal consistency water demand,setting time and soundness of cement can meet the standard.The harden cement has lower porosity of 0.0413cm 3/g and lower hydrate heat which is 253kJ/kg.
