摘　　要：以多孔膨胀珍珠岩为载体,三乙醇胺、乙二醇、十二烷基苯磺酸钠和三聚磷酸钠为助磨剂复配了一种矿渣粉磨用多孔膨胀珍珠岩复合助磨剂,研究它对矿渣的助磨效果。将不同加入量的复合助磨剂在相同的粉磨条件下与矿渣共磨20~95 min,测定各矿渣粉的比表面积和45μm筛余量,并与空白样品对比;然后对粉磨65 min所得的矿渣粉用图像分析仪和扫描电镜进行了形貌分析,用激光粒度分布仪进行了粒度分析;同时又研究了此复合助磨剂对矿渣-水泥体系标准稠度用水量、凝结时间、胶砂强度等各项性能的影响。结果表明:本试验的复合助磨剂的助磨效果好,对矿渣水泥的性能无损害且能够提高胶砂强度;矿渣的小磨试验中此复合助磨剂的最佳用量为矿渣质量的0.04%~0.08%,粉磨时间应大于35 min后矿渣粉中10~20μm颗粒的含量相对空白明显增加。A kind of composite grinding aid was developed of carrier-porous expanded perlite and grinding aids composed of triethanola mine,glycol,dodecylbenzene sulfonic acid sodium and sodium tripolyphosphate.Different amounts of composite grinding aid made ourselves were added to slag which was ground for 20 to 95 minutes in the same condition.Specific surface areas and residue on 45 μm-sieve of slag using grinding aid were tested after grinding every 15 minutes and compared with that of the slag without grinding a...
