| 摘 要： | 利用三乙醇胺精馏塔底残液、甘油蒸馏残余料等工业下脚料，研制出了新型高效水泥助磨剂，实验室小磨试验结果表明，优化的助磨剂对于硅酸水泥和复合硅酸盐水泥都有良好的助磨效果，能够降低45μm筛余值11．4％-20．0％，增大比表面积2-10m^2/kg，并在一定程度上改善了水泥的粒度分布。同时，水泥的抗折抗压强度也得到了提高。

| Abstract: | Novel cement grinding aids were formulated by residual liquids from rectification tower of triethanolamine, glycerin and other plants. The results of small mill indicated that formulated cement grinding aids not only showed effective grind for silica and formulated silicate cements, decreased 45μm sieve residual value of 11.4% -12.0%, and increased surface area of 2 -10 m^2/kg but also made distribution of particle size reasonable while flexural strength and compressive strength was improved. |
