To further understand the deterioration effect of NaCl and KAc deicers on concrete materials, designed tests were carried out with laboratory-fabricated concrete samples. In both cases, the compressive and splitting tensile strengths of such samples decreased considerably after 3, 7, and 15 freezing/thawing (F/T) and wetting/drying (W/D) cycles.

Calcium Chloride Especially

Calcium chloride is an ionic substance composed of calcium and chlorine that’s highly soluble in water, and considered a deliquescent (a substance able to melt or dissolve). 2 It’s a type of calcium salt that remains solid when in room temperature, and exhibits behaviors similar to an ionic halide. 3 Calcium chloride is usually made by dissolving limestone (calcium carbonate) or marble in ...
