【摘要】 本文通过酯化反应合成了马来酸三乙醇胺酯（MT）,并以合成的马来酸三乙醇胺酯为单体,与甲基丙烯酸和马来酸酐通过水溶液聚合,制备分散性好的高分子助磨剂（PMA）。以三乙醇胺（TEA）作为对比,研究了不同掺量下PMA对不同龄期水泥强度的影响,借助于XRD、SEM、FTIR、TG-DSC等测试手段对水泥的水化程度和水化产物的微观结构进行分析。结果表明:PMA助磨剂能够促进C₃A和C₃S的水化,提高C-S-H凝胶的聚合度,从而提高水泥水化产物质量,改善水泥水化产物的结构。更多还原

【Abstract】 Maleic acid triethanolamine ester（ MT） was prepared by esterification firstly. A novel modified Alkamines polymer grinding aids（ PMA） was prepared with Maleic acid（ MA）,methyl acrylic and the synthesis of MT by aqueous polymerisation. To get a valuable result,a reference sample was made with triethanolamine（ TEA）. Influence of triethanolamine（ TEA） on concrete strength were investigated; and mechanism of PMT on the cement hydration process and microstructure is discussed by means of XRD,SEM,TG-DSC and FTIR. Research results indicate that PMA accelerated hydration process of C₃A and C₃S,and improved the degree of C-S-H gel. PMA also improved the quality and the structure of the hydration products.更多还原
