摘　　要：选取闷化和自然冷却两种不同处理工艺的钢渣,粉磨成钢渣粉掺入水泥中,研究钢渣细度和掺量对水泥物理性能的影响。结果表明,钢渣粉掺量越大,水泥强度下降幅度越大,安定性不合格现象越严重。而随着钢渣比表面积的增加,水泥强度不一定增加,往往反而下降。In order to research the effect of fineness and content of steel slag on cement physical properties, two different treatment processes steel slag （hot stuffy and natural cooling） were grinding into powder and mixed with cement. The results showed that the more steel slag added, the more the decrease amplitude of cement strength happened, and also the more times of unsoundness problem could be occurred. The cement strength not always increase with the steel slag specific surface area increasing, and it may be decrease sometimes.
