This chapter treats the deterioration of reinforced concrete elements and structures by chloride ingress. First, some typical structure cases are introduced to illustrate the impact of chloride ingress on the structural performance. The mechanisms of chloride ingress in concrete and chloride‐induced corrosion of embedded steel are explained in depth, together with a comprehensive analysis of the factors influencing the processes. Based on the available knowledge, mechanism‐based and empirical models are given for chloride ingress, corrosion initiation, and corrosion current for engineering use. Some simulations are performed for typical engineering applications. Finally, the impact of steel corrosion on structural performance of concrete elements is discussed, and the fundamental issues for durability design against chloride‐induced corrosion are elucidated.
