摘　　要：以窑灰活化煤矸石为混合材取代部分水泥熟料,测试其凝结时间、强度;以30%的取代量,研究了水泥的抗硫酸盐侵蚀和抑制碱集料反应性能。结果表明:(1)窑灰活化煤矸石的掺入使水泥凝结时间有所延长,掺入10%的窑灰活化煤矸石在一定程度上提高了水泥的后期强度,继续增加窑灰活化煤矸石的掺量,水泥的强度有所下降,掺量到30%时强度下降比较明显。(2)窑灰活化煤矸石的掺入,可使水泥的抗硫酸盐侵蚀性能有比较大的提高,抑制碱集料反应能力有所改善,但改善幅度有限。Replaced some cement clinker by flue dust activated coal gangue as admixture and tested its setting time and strength. When the substitute was 30%, studied the performance of sulphate resistance and inhibiting alkali aggregate reaction. The results show as follows： （1） adding flue dust activated coal gangue make the setting time longer, and when the substitute is 10%, the late strength of the cement increased at a certain extent, but more substitute may go against the cement strength, and the strength falls clearly as the substitute reaches 30%. （2） Adding flue dust activated coal gangue can make sulphate resistance increase greatly and can improve the performance of inhibiting alkali aggregate reaction at some limited extent.
