摘　　要：通过使用矿渣微粉等量替代混凝土中的普通硅酸盐水泥试验分析,研究矿渣微粉替代量对混凝土和易性和强度的影响,以及龄期对抗压强度和抗拉强度的影响。试验结果表明:矿渣微粉可以有效改善混凝土拌合物的保水性和黏聚性,提高混凝土的后期强度;低掺量(≤40%)矿渣微粉混凝土早期强度大于基准混凝土(掺量0);掺矿渣微粉混凝土的强度随着掺量的增加而降低。By analyzing by experiments the same amount of slag powder instead of ordinary portland cement concrete,test its effect on concrete workability and strength,and its ages on the compressive strength and tensile strength.The test results showed that：the slag powder could effectively improve the concrete mixture water retention and cohesiveness and increase the later concrete strength.Low volume（≤40%）slag powder concrete early strength was greater than the reference concrete（volume 0）;The strength of concrete mixed with slag powder decreased with the increasing amount of volume.
