摘要 钢渣尾泥是转炉钢渣经湿法球磨、磁选处理后的副产品,其水硬胶凝活性较低。本文介绍了物理和化学活化技术对钢渣尾泥的活化研究,实验结果表明,物理活化法可以显著改善钢渣尾泥的活性,石膏类激发剂对球磨钢渣尾泥化学活化效果较好,烧石膏掺入4%,或者天然石膏掺入5%时,尾泥粉的活性均能达到一级微粉的国标要求。钢渣尾泥粉和钢渣尾渣粉存在互补性,将二者进行复合配比配制钢渣水泥时,尾渣粉可以提高钢渣水泥的力学强度,而尾泥粉则可以改善钢渣水泥的体积安定性。

Abstract: Steel slag mud is a byproduct generated after the wet ball milling and magnetic separation of BOF slag, whose hydraulic cementitious property is relatively poor. The physical and chemical activation technologies of steel slag mud were introduced. The experimental results show that physical activation can significantly improve the mud activity. The stimulating agent, such as gypsum and its related products, shows good chemical activation effect on the mud. When mixed with 4% plaster of Paris or 5% natural gypsum, the activity of mud powder can meet the national standard for the first-class micro-powder. Complementarities exist between the mud powder and the slag powder, both of which can be mixed in proper proportions to produce steel slag cement. The slag powder favors the increase of mechanical properties while the mud powder improves the volume stability of steel slag cement.
