摘　　要：利用灰色关联分析方法，研究了矿渣微粉的粒度分布对矿渣水泥性能的影响。研究结果表明：0-5μm、5-11μm的矿渣微粉颗粒分别对3 d、28 d强度有显著影响；0-23μm的矿渣粉颗粒对3 d，28 d强度起增进作用；水泥强度随〉23μm的矿渣微粉颗粒含量增大而降低。因此，可以通过优化矿渣微粉的粒度分布来改善水泥性能。The effects of particle size distribution of slag powder on properties of cement were investigated by grey volume correlation analysis method. Research results indicate that the slag particles of 0-5μm and 5-11μm have significantly effect on the 3 d and 28 d strength respectively;Slag particles of 0-23μm have enhancing effect on 3 d and 28 d strength. However, strength decreases with in-creasing of slag particles of over 23μm. Therefore, cement properties can be improved by optimizing particle size distribution of slag powder.
