Physical and Chemical Effects of Deicers on Concrete Pavement: Literature Review

The purpose of this research was to conduct a review of the literature and summarize the effects of several commonly used deicers on concrete pavement. Sodium chloride, calcium chloride, magnesium chloride, and calcium magnesium acetate (CMA) and the effects of their respective ions are specifically discussed, and 10 different studies published between 1995 and 2012 are summarized. Deicers can affect concrete both physically and chemically. Physical effects are typically manifested as cracking and salt scaling, while chemical effects can result from reactions involving cement hydration products, aggregates, or reinforcing steel. Most strategies used by researchers to directly compare the effects of various deicers on concrete involve freeze-thaw cycling, wet-dry cycling, and/or soaking mortar or concrete specimens. Regardless of variations in testing methods and specimen characteristics, the results from nine of the ten studies summarized in this research indicate that specimens exposed to sodium chloride experienced only minor, if any, adverse effects, while specimens exposed to calcium chloride, magnesium chloride, or CMA experienced significant deterioration, including scaling, cracking, mass loss, and compressive strength loss.
