The crack and seepage of exterior wall are commonly concerned problems in civil engineering, which are mainly due to the poor shrink-resisting ability of traditional masonry mortar. Different amount of polyamide latex was added into masonry mortar to test and compare their dry shrinkage. The result shows that the more of latex were added into mortar, the stronger of anti-dry shrinkage of it is; 5% latex was added into external wall mortar, it could resist the deformation which caused by temperature and humidity, and co...
