Research on Polymer Latex Modify Comprehensive Properties of Cement Mortar
Aimed for current situation that most scholars concerned with mechanics, deformation, flow performance of modified cement mortar, the paper selected carboxyl styrene-butadiene latex as the modified material, researched on cement mortar’ water reducing effect, wear resistance, corrosion resistance-mechanical properties, drying shrinkage before modifing and after modifing. Compared cement fine mortar’s properties with cement mechine-made mortar’s properties before and after modification. Research results showed that the addition of carboxyl SB latex, the overall performance of cement mortar is greatly improved, and with the increase of polymer cement ratio, this improvement trend is more obvious, those changes especially are suitable for extra-fine cement mortar. The results clarify the properties variation law of cement mortar before and after modification, this provides scientific guidance for polymer latex modified cement mortar mix design.
