Frost Resistance and Weatherability

NUMBER OF CYCLES OF FREEZING AND THAWING PAE-MODIFIED MORTAR 

According to the data of Solomatovl on latex-modified concrete using a copolymer of vinyl acetate and didutyl malcatc, the wet-cured concrete is more liable to be affected by freeze-thaw cycles than the dry-cured concrete. 

A few studies on the frost resistance of latex-modified mortar and concrete have been conducted in diloridefi l and sulfatel l solutions.

Generally, the latex-modified mortars provide the high retention of Qexural strength. SBR-and PAE-modified mortars have a higher weatherability than the other latex-modified mortars.
