Recently, sodium chloride (rock salt) and calcium chloride have been used as highway deicing salts, which can cause serious corrosion and environmental problems. These problems include deterioration of portland cement concrete bridge decks through chloride in corrosion of reinforcing steel; corrosion of structural steel in bridge structures and other highway construction; corrosion of automobile parts; pollution of drinking water sources by sodium and chloride ions in runoff; and harm to roadside vegetation. The Federal Highway Administration (FHWA) initiated work aimed at developing substitutes for chloride salts in deicing; research conducted by Bjorksten Research Laboratories [8] identified calcium magnesium acetate (CMA) as a potentially acceptable, non-corrosive biodegradable alternative.

Such materials would work also in winter environments containing road anti-icing agents. Chlorides are mostly used as de-icing chemicals [13] but at the same time they are considered as the most aggressive substances used during the winter road maintenance [14]. In order to reduce the harmful impact of chlorides on the vehicles and road infrastructure, they are gradually substituted by less aggressive agents, such as calcium magnesium acetate. While coating corrosion tests in NaCl solutions are commonly implemented, the studies in a CMA solution are unprecedented. Hence this comparison of the coating corrosion resistance in two corrosion environments: a calcium magnesium acetate (CMA) and a sodium chloride (NaCl) solution.
