摘　　要：以三异丙醇胺、三乙醇胺、丙二醇、乙二醇、山梨醇和二乙二醇6种不同的醇及醇胺类单体为助磨剂，添加的质量分数均为0．04％，粉磨30min，分析粉磨后的水泥颗粒形貌、比表面积、筛余量、粒径分布以及3d、28d水泥试块的强度等。结果表明，6种助磨剂均能改善粉磨效率，提高胶砂强度。Taking six kinds of alcohol and amine monomer including triisopropanolamine, triethanolamine, propylene glycol, ethylene glycol, diethylene glycol and sorbitol as cementgrinding aids, the cement particle particle size distribution and 3 an mass ratio of 0.04% and ball-milli Can improve the grinding efi ciency morphology, specific surface area, sieve residue mass ratio, d 28 d cement mortar strength were analyzed with the gnnding aids ng 30 minutes. The results indicate that the si× grinding aids and increase the cement mortar strength.
