Abstract：Polymers can significantly improve the workability,flexural strength and corrosion resistance performance of cement-based materials. In this paper,the workability,mechanical properties and long-term durability of cement mortars modified by PVDF latex in different P/Cs were studied. The results show that the PVDF latex has some extent of water reduction effect to the cement mortars,and the water retention and cohesion property is good. In addition,the latex can increase the air content of cement mortars. It can improve the deformation ability of mortar,improve the defects of brittleness,and increase the tensile bond strength of mortar. Moreover,the modified mortars have higher resistance to chloride ion penetration,lower water absorption and higher anti-shrinkage performance.
