Abstract Chloride ion corrosion of steel bars is one of the important reasons for the decline of durability and service life of concrete structures. Due to the complexity of concrete structure, the migration process of chloride ions in concrete is diversified. Therefore, it is difficult to show the transport mechanism of chloride ions in concrete by a single experimental study. It is necessary to explore the transmission process and mechanism of chloride ions in concrete through theoretical simulation on the basis of experimental research. This paper summarizes the relevant models and methods of chloride transport, points out the advantages and disadvantages of existing models, and prospects the research direction of chloride transport models.
