摘要/Abstract

摘要： 为克服三乙醇胺早强剂对水泥抗折强度和后期强度的影响,合成了马来酸三乙醇胺酯,并通过背散射电子成像(BSE)和BET分析,研究了马来酸三乙醇胺酯对水泥水化程度、C-S-H含量和水泥水化28 d分形维数的影响。结果表明:马来酸三乙醇胺酯可促进水泥水化尤其是水泥中硅酸盐相的水化;复掺马来酸三乙醇胺酯和聚羧酸减水剂,可显著提高水泥水化产物中C-S-H的含量;三乙醇胺降低了水泥石28 d的分形维数,马来酸三乙醇胺酯单掺及与聚羧酸减水剂复掺则使水泥石28 d的分形维数提高。由此可见,马来酸三乙醇胺酯作为增强型水泥早强剂具有广阔的应用前景。

Abstract: In order to overcome the negative effect of triethanolamine on the flexural strength and later strength of cement, triethanolamine maleate was synthesized, and the hydration degree, the amount of C-S-H and the 28 d fractal dimension of cement hydration products were studied through BSE and BET analysis. The results show that triethanolamine maleate promotes the hydration of cement, especially the silicate phase in cement. The addition of triethanolamine maleate and polycarboxylic acid water reducer significantly increases the amount of C-S-H in cement hydration products. Triethanolamine decreases the fractal dimension of cement stone at the age of 28 d.The effect of mixing triethanolamine maleate alone and mixing triethanolamine maleate and polycarboxylic acid water reducer together increase the fractal dimension of cement stone at the age of 28 d. It can be seen that triethanolamine maleate has broad application prospects as an enhanced cement early strength agent.

Key words: cement hydration, triethanolamine, triethanolamine maleate, early strength agent, microstructure
