摘　　要：为了进一步分析聚合物对水泥基材料抗压性能的影响,本文通过在水泥砂浆中添加丙烯酸乳液、环氧树脂、丁苯乳液三种有机物及超细矿物掺合料进行试验。结果表明:聚合物乳液的掺入,抗压强度虽有不同程度的降低,本次试验环氧树脂对强度的贡献不稳定;硅灰和超细粉煤灰对砂浆的抗压强度和抗折强度有不同程度的提高。To study further the influence of polymer to cement base material compressive performance, inthis paper, acrylic emulsion, epoxy resin, and butyl benzene latex is added in the organic matter andsuperfine mineral admixture of cement mortar for test. The results show that the compressive strength ofpolymer emulsion decreases with the incorporation of polymer, and the contribution of epoxy resin tostrength is unstable. The compressive strength and flexural strength improved with the incorporation of silica fume and ultrafine fly ash.
