    Abstract. The most common cause of degradation of reinforced-concrete structures today is the chloride-induced corrosion of reinforcing bars. While marine structures are obviously susceptible to this problem, inland structures in regions where anti-icing and de-icing salts are used are subjected to even greater concentrations of salts and hence rapid degradation.
