摘　　要：矿渣微粉在水泥中的作用分为火山灰效应和填充效应,利用比强度分析法和增强效应因子法来分析这两种效应在水泥中的作用情况。结果表明:在水泥硬化浆体中火山灰效应起主导作用,约占总效应的80%且随着掺量的增加和龄期的延长其效应逐渐明显;填充效应随着龄期的延长逐渐明显,但随着掺量的增加逐渐减小,对强度的贡献率一般为负值。两种效应在28d均达到最大值。The study tries to divide the effect of superfine slag powder into pozzolanic effect and filling effect, using method of specific tenacity analytic and factor of enhancement effect to a analysis them. The results are that： the pozzolanie effect is the main factor and is amount to 80% in the cement,the effect is improved with the increasing of content and the time;the filing effect is weakness with the increasing of content and gradually obvious with the time. Generally speaking,it is disadvantage to the strength of the cement. The both of the effect of superfine slag powder contribute most on slag cement＇s 28d strengths.
