The chloride-induced corrosion of reinforcements has been identified as the main cause of cracking in reinforced concrete due to the expansion of corrosion products.The research achievement were summarized from three aspects including the chloride-induced steel corrosion build-up,corrosion-induced expansive force and concrete cover cracking.Some suggestions were put forward to provide a guide for the further research.It is pointed out that the simplified models that consider the concrete as a homogeneous material cannot accurately describe the concrete cover cracking process due to the chloride-induced steel corrosion,and future researches should focus on the establishment of a mesoscopic model of concrete.In addition,the corrosion product distribution model under natural conditions is not unique,and there is a big difference between the simulated 2D model and the actual 3D structural member.The difference between the non-uniform steel corrosion induced by artificial environment and natural corrosion is not clear,and further research work is still needed.
