When subjected to loading or thermal shrinkage, reinforced concrete structures usually behave in a cracking state, which raises\nthe risk of bar corrosion from the working environment. The influence of cover cracking on chloride-induced corrosion was\nexperimentally investigated through a 654-day laboratory test on cracked reinforced concrete specimens exposed to chloride\nsolution.Theconcrete specimens have a dimension of 100mmÃ?â?? 100mmÃ?â?? 400mmand a single prefabricated crack at the midspan.\nWhen the percentage concentration of chloride ion (0.6%, 1.2%, 2.1%, 3.0%, and 6.0%) and crack width (uncracked, 0.2, 0.3, 0.4,\nand 0.5 mm) are taken as variables, the experimental results showed that the corrosion rates for cracked specimens increased with\nincreasing percentage concentration of chloride and increasing crack width. This study also showed the interrelationship between\ncrack width and percentage concentration of chloride on the corrosion rate. In addition, an empirical model, incorporating the\ninfluence of the cover cracking and chloride concentration, was developed to predict the corrosion rate. This model allows the\nprediction of the maximum allowable
