水性环氧树脂改性碱矿渣水泥砂浆的性能增强研究

Research on Performance Enhancement of Waterborne Epoxy Resin Modified Alkali Slag Cement Mortar

通过改变水性环氧树脂溶液的掺量对碱矿渣水泥砂浆(AAS)的力学和耐SO 2-4腐蚀性进行分析。研究发现:加入0%~15%环氧树脂溶液,改性AAS的R c有降低的现象;在加入9%环氧树脂溶液时,AAS的28d龄期R f较空白组高27.1%,其折压比高39.9%;耐SO 2-4能力较好。由此可知,掺入适量聚合物环氧树脂溶液可以有效地改善AAS的力学和耐SO 2-4腐蚀性能。

This article analyzes the mechanics and SO 2-4corrosion resistance of alkali slag cement mortar(AAS)by changing the content of the aqueous epoxy resin solution.The study found that:adding 0%~15%epoxy resin solution,the R c of modified AAS decreased;when adding 9%epoxy resin solution,the 28d Rf of AAS was 27.1%higher than that of the blank group.The ratio is 39.9%higher;the resistance to SO 2-4 is better.It can be seen that mixing an appropriate amount of polymer epoxy resin solution can effectively improve the mechanical and SO 2-4corrosion resistance of AAS.
