本研究将探讨混凝土中涂覆钢筋和未涂覆钢筋在开裂和循环荷载下的耐腐蚀性，以及修复这些腐蚀部分的方法。过去的研究是对钢筋混凝土块进行的，通常没有开裂和卸载，受到温度变化和暴露于浓氯化物溶液的湿/干循环的影响。为了更真实地模拟现场条件，在调查中打算包括裂缝和循环加载的钢筋混凝土板。过去的研究表明，在这种条件下，裂纹界面处的棒状涂层有可能发生磨损和开裂。

The research will investigate the corrosion resistance of coated and uncoated reinforcement in concrete subjected to cracking and cyclic loading and methods to repair such sections undergoing corrosion. Past research has been conducted on reinforced concrete blocks, generally uncracked and unloaded, subjected to temperature variations and wet/dry cycles of exposure to concentrated chloride solutions. To more realistically simulate field conditions, it is intended in the investigation to include cracked and cyclically loaded reinforced concrete slabs. Past research has indicated that under such conditions it may be possible to wear and crack bar coatings at crack interfaces.
