Investigation of the Long-Term Effects of Magnesium Chloride and Other Concentrated Salt Solutions on Pavement and Structural Portland Cement Concrete

The objective of this research project is to investigate the short and long-term effects of high concentrations of salts (including magnesium chloride) and to (1) determine the long-term effects of concentrated solutions of magnesium, sodium and calcium chloride as well as CMA or other alternative liquid deicers on durable portland cement concrete; (2) estimate the potential for reduction in performance and service life for pavements (jointed plain, reinforced and continuously reinforced) and structures subjected to various concentrated deicing brines; (3) identify alternative protective or deicing/anti-icing strategies which minimize potential impacts to durable portland cement concrete while providing acceptable winter maintenance results that are being increasingly applied to concrete during anti-icing and de-icing activities.
