Changes

Chloride based deicers are highly corrosive and can cause significant damage to vehicles, steel bridges, railings and other metal infrastructure. They can also cause damage to concrete structures by accelerating corrosion of re-bar within the concrete, which poses a problem for bridges, parking lots above underground garages or other contexts where the concrete contains metals. The salts may also react with the cement paste causing deterioration of the cement matrix in poured and pre-cast concrete pavers. Magnesium chloride (MgCl2) is particularly reactive in this regard, resulting in a decrease in concrete compressive strength (e.g. Shi 2009<ref>Shi, X., M. Akin, T. Pan, L. Fay, Y. Liu and Z. Yang (2009). Deicer Impacts on Pavement Materials: Introduction and Recent Developments.
