矿渣微粉粒度分布对水泥性能的影响

摘要

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.%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。
