摘　　要：利用抗压试验、抗折试验、扫描电镜等方法,探讨了水泥掺量对聚合物砂浆性能的影响.试验结果表明:当水泥掺量为115%时与水泥掺量0%时相比,聚合物砂浆的抗折强度提高95%,抗压强度提高74%,折压比也相应有所提高.但加入量高于115%时,导致水泥比表面积过大,抗折强度和抗压强度均有所下降.In order to analysis the polymer mortar performance,with different cement volume polymer mortar specimens by compression tests,bending tests and scanning electron microscopy method,test results indicate that： 115 % and 0 % of the cement dosage compared to,flexural strength of polymer mortar increased 95 %,compressive strength increased 74 %,the ratio of flexural and compressive strength increased accordingly.However,when the dosage is higher than 115 %,resulting in large specific surface area of cement,bending strength and compressive strength has declined.
