针对外墙外保温体系用聚合物抹面砂浆在经受冻融循环试验条件下的应变和力学性能进行研究，结果表明：聚合物抹面砂浆经历一定次数的冻融循环后，轻质系列聚合物抹面砂浆总微应变量和压折比增加量均小于常用聚合物抹面砂浆，具有更好的柔韧性，提高了砂浆的耐久性。同时，利用 SEM 对三种砂浆进行了微观机理研究。
針對外牆外保溫體繫用聚閤物抹麵砂漿在經受凍融循環試驗條件下的應變和力學性能進行研究，結果錶明：聚閤物抹麵砂漿經歷一定次數的凍融循環後，輕質繫列聚閤物抹麵砂漿總微應變量和壓摺比增加量均小于常用聚閤物抹麵砂漿，具有更好的柔韌性，提高瞭砂漿的耐久性。同時，利用 SEM 對三種砂漿進行瞭微觀機理研究。

It was studied on the mechanical properties and strain of polymer plaster mortars for external thermal insulation composite systems(ETICS) under freeze-thaw cycle test.The results demonstrated that after freeze-thaw cycle test,the total micro-strain and incre-ment of the flexural and compressive strength ratio of lightweight polymer mortar were less than commonly used polymer mortar.As a re-sult,the lightweight polymer mortar have better flexibility and durability.At the same time,it was studied on the microstructure using SEM about these three mortars.
