Deicer Scaling Mechanisms in Concrete
The objective of this research was to investigate the mechanism by which deicers cause deterioration of concrete. Previously proposed mechanisms based on thermal shock and direction of freeze were experimentally isolated. The effect of direction of freeze was found to be insignificant. Deterioration associated with saturated calcium chloride solutions was found to be dependent upon relative humidity and temperature. It has probably led to the observation that calcium chloride is generally more aggressive as a deicer than sodium chloride. The mechanism of deicer deterioration of concrete shown to be common for many deicers was found to exist only with weak concentrations and only under freeze-thaw conditions. The effect of low concentrations of calcium chloride on concrete was greater than that of water or of more concentrated solutions. (Author)
