A calcium magnesium acetate (CMA)-based deicing product has been tested as an alternative to salt-based deicers, which are corrosive to steels used in the construction of bridges, roadways, and automobiles. The CMA-based deicer showed much lower corrosion rates than salt-based deicers in alternative immersion tests. Electrochemical testing of steels in CMA-based deicer suggests that although similar corrosion potentials to salt-based deicers occur with the CMA-based product, corrosion currents, and thus corrosion rates, are greatly reduced. Results of alternative immersion and electrochemical testing are presented. (Author/publisher)
