在水泥砂浆中加入不同种类的有机硅制得有机硅改性防水砂浆,以冻融循环后的质量损失率和抗压强度损失率来表征防水砂浆的抗冻融性能,结果表明,不同的冻融循环次数后,有机硅改性防水砂浆的质量损失率低于普通水泥砂浆,但抗压强度损失率高于普通水泥砂浆,有机硅改性防水砂浆的外观脱落情况较普通水泥砂浆好,总体抗冻融性能有所改善。从SEM照片可以发现,有机硅改性防水砂浆内部形成了网络结构。

Silicone modified waterproofing mortar is prepared by adding different silicones to cement mortar, and its freeze- thawing resistance is characterized by mass loss rate and compressive strength loss rate after freeze-thawing cycle. The results show that after different freeze-thawing cycle, the mass loss rate of silicone modified waterproofing mortar is lower than ordinary cement mortar while its compressive strength loss rate is higher than the latter, and the appearance is better than the latter too. So the overall freeze-thawing resistance of silicone modified waterproofing mortar is improv...
