利用抗压试验、抗折试验及扫描电镜等方法,探讨了聚酯纤维对聚合物砂浆性能的影响.试验结果表明:当聚酯纤维掺量为0.8%与聚酯纤维掺量0%相比,聚合物砂浆的抗折强度提高17%,抗压强度提高5%,折压比也相应有所提高.但加入量高于0.8%时,抗折强度和抗压强度均有所下降.
利用抗壓試驗、抗摺試驗及掃描電鏡等方法,探討瞭聚酯纖維對聚閤物砂漿性能的影響.試驗結果錶明:噹聚酯纖維摻量為0.8%與聚酯纖維摻量0%相比,聚閤物砂漿的抗摺彊度提高17%,抗壓彊度提高5%,摺壓比也相應有所提高.但加入量高于0.8%時,抗摺彊度和抗壓彊度均有所下降.

In order to analysis the polymer fiber performance,with different polyester content polymer mortar specimens by compression tests,bending tests,scanning electron microscopy method,test results indicate that:0.8% of the cement dosage and cement dosage compared to 0%,flexural strength of polymer mortar increased 17%,compressive strength increased 5%,fold compression ratio increased accordingly.However,when the dosage is higher than 0.8%,resulting in large specific surface area of cement,bending strength and compressive strength has declined.
