【摘要】：为了减少三乙醇胺的使用成本,提高其助磨和增强效果,用一元有机酸盐化三乙醇胺合成DOGA系列水泥助磨剂。通过分析水泥粉体的比表面积、筛余量、粒度分布以及水泥硬化浆体的抗压强度、TG-DSC,研究DOGA系列水泥助磨剂对水泥性能的影响。结果表明,以三乙醇胺为参比项,DOGA系列水泥助磨剂改善了助磨和增强效果,其中DOGA3的助磨和增强效果最好,在最佳掺量0.05%时,45μm筛余降低21.1%、比表面积增加了21 m2/kg、3~32μm增加了2.14%,3 d、28 d抗压强度分别提高了2.1 MPa、4.4 MPa。
[Abstract]:In order to reduce the use cost of triethanolamine and improve the grinding aid and strengthening effect of triethanolamine, DOGA series cement grinding aids were synthesized by salinizing triethanolamine with organic acid. The specific surface area and sieve allowance of cement powder were analyzed. The effect of DOGA series cement grinding aids on the properties of cement was studied by using the particle size distribution and the compressive strength of cement hardened paste. The results showed that triethanolamine as a reference term and DOGA series cement grinding aids improved the grinding aid and strengthening effect. The grinding and strengthening effect of DOGA3 is the best, and the rest of 45 渭 m sieve decreases by 21.1and the specific surface area increases by 21 m2 / kg ~ (32) 渭 m by 2.14 ~ 3 d ~ (28) d compressive strength of 2.14m ~ (3 d) ~ (28) d, respectively, by 2.1 MPA ~ (4.4) MPa at the optimum dosage of 0.05 渭 m, and the specific surface area is increased by 21 m ~ (-2) / kg ~ (32) 渭 m.
