摘　　要：水泥助磨剂是一种新型水泥粉磨节能技术。利用工业废弃物PVA废料、BDO残渣,与三乙醇胺、PTMEG、甘油等物质复配水泥助磨剂,研究其在水泥粉磨中的作用以及对水泥性能的影响。结果表明,配制的P型和W型复合助磨剂应用于水泥粉磨,在不同程度上降低了水泥筛余,增大了水泥比表面积,优化了水泥颗粒级配,对水泥早期强度贡献最大的3~32μm颗粒含量增加,使水泥3 d抗压强度和抗折强度得到提高。Cement grinding aid is a new energy-saving technology for cement grinding.Using industrial waste such as PVA waste,BDO residue,triethanolamine,PTMEG,glycerin and other substances to mix cement grinding aids,the effect of them on cement grinding and cement properties was studied.The results show that the p-type and W-type composite grinding aids used in cement grinding can reduce the cement screen residue,increase the specific surface area of cement,optimize the cement particle gradation,increase the content of 3~32μm particles which contribute most to the early strength of cement,and improve the 3 d compressive strength and flexural strength of cement.
