外墙外保温用聚合物砂浆耐候性研究

Analysis on polymer mortar of EICS external wall under atmospheric exposure test

对外墙外保温体系在长期经受热雨循环和热冷循环下因耐候性不足而破坏的情况进行了分析,从外墙外保温体系聚合物砂浆经历一定次数的热雨循环和热冷循环后,其抗压强度、抗折强度以及粘结强度均有不同程度的下降等方面进行了论述,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。

This paper analyzes the destroy of External thermal Insulation Composite Systems（EICS） under atmospheric exposure test of hot-rain system and hot-cold system, The experiment results indicate that the compression strength, the rupture strength and the cohesional strength of polymer mortar of EICS all decline at some degrees. And this paper also analyzes the failure mechanism of polymer mortar under atmospheric exposure test.
