摘　　要：对外墙外保温体系用聚合物抹面砂浆在耐候性试验环境下的力学性能进行研究。试验结果表明:外墙外保温体系用聚合物抹面砂浆经历一定次数的热雨循环和热冷循环后,抗压强度、抗折强度及粘结强度均有不同程度的下降,压折比提高。同时对外墙外保温用聚合物砂浆耐候性破坏机理进行了研究分析。It was studied the mechanical properties of polymer finishing mortar for external thermal insulation composite systems（ETICS） under weathering test.The experiment results indicated that the compression strength,the flexural strength and the bonding strength of polymer finishing mortar for ETICS all declined to different extent,but the flexural and compressive strength ratio of polymer finishing mortar increased.And it was also analyzed the damage mechanism of polymer finishing mortar under weathering test.
