Deicing composition

摘要

A deicing composition comprises (a) a metal halide salt and (b) a lithium salt of a carboxylic acid or a lithium nitrate, wherein the molar ratio of the lithium of component (b) to the metal of component (a) is from 10 percent to 80 percent. The deicing composition may be used to deice a concrete surface. A lithium salt of a carboxylic acid or a lithium nitrate may be used in a deicing composition, to reduce the concrete-deteriorating effect of said deicing composition. The deterioration may be caused by alkali-silica reaction. The lithium salt of a carboxylic acid or lithium nitrate may be added at a percent solids level such that the eutectic point of the deicing composition is not lowered to avoid adversely affecting the deicing characteristics of the deicing composition.
