The durability of the concrete under salt-freezing environment is rapidly degraded due to the coupling effect. In this review, the research results of chloride transport under freeze-thaw cycles were summarized according tothe mechanical behavior, the diffusivity of chloride and several protective measurements. In freeze-thaw action, the concrete damage could be divided into two stages, and the two-stage damage theory was proposed to describe the initial and diffusion of damage, respectively. Some experimental methods were used to quantitatively investigate the damage degree of concrete. The relationships between damage degree and diffusion coefficient wereestablished to deal with the acceleration effect of freeze-thaw cycle on chloride transport. The influence of influencing factors on the chloride transport under freeze-thaw cycle was investigated. The existing studies are mostly obtained from lab-scale experiments, thus restricting the quantitative evaluation of the life of actual concrete structures. A series of protective measures, such as surface treatment, electrochemical rehabilitation/protection and addition of admixture were proposed, and afuture research direction in this field was discussed based on three aspects, i.e., experiment, theory and modelling.
