摘　　要：研究了羟乙基甲基纤维素和乙烯基共聚物两种聚合物干粉改性砂浆在不同养护条件下的粘结抗拉强度。试验结果表明,聚合物干粉的种类、掺量以及养护条件对水泥砂浆的粘结抗拉强度有着显著影响。两种聚合物干粉改性的水泥砂浆具有良好的抗冻融循环性能和耐高温性能。The adhesion strength of hydroxyethyl methyl cellulose modified mortar and ethylene copolymer modified mortar were studied at different curing condition. The results showed that the types of polymer dry mix, its content and curing condition had remarkable effect on the adhesion strength of cement mortar. These two kinds of polymer modified cement mortar had good freeze-thaw resistance and high temperature resistance property.
