Development of Polymer Modified Cement Mortars for Waterproof

摘要

The paper describes the raw materials and properties of polymer modified cement mortars for waterproof.In this paper,the following aspects were discussed,the effect of different polymer cement ratio on the ratio of compressive strength to flexural strength,the mechanism of the improvement of impermeability,durability and viscosity by the cooperation of super mineral powder and re-dispersible powders respectively.In addition the effect of graded sand and fiber on the cracking resistance and contractility of mortar were also studied.
