Title: Effects of Cold Weather Construction on the Compressive Strength of Concrete Masonry Walls

Abstract:The effect of cold weather on the strength of plain concrete block masonry walls was studied in a program of tests on 49 specimens. Exposure to cold weather began at various times after construction. Following exposure the walls were cured in a normal laboratory environment under varying moisture conditions and then tested. Results indicate that exposure of walls to freezing conditions does not significantly impair the final strength, providing further hydration of the mortar is possible following freezing. The most significant factor affecting the strength of the walls is moisture loss from the mortar inhibiting hydration.
