Research Progress on the Transport and Prediction of Chloride Ions in Concrete Structures

Abstract

Reinforced concrete structures are widely used in practical engineering, and the durability issues of such structures under chloride environments have been a hot research topic. Chloride ions can cause corrosion of internal steel bars in structures under the action of chloride salt, leading to structural cracking, decreased bearing capacity, and ultimately affecting the structural safety during service life. Therefore, comprehensive and systematic research on chloride ion transport and prediction in concrete structures is crucial. This paper reviews the recent research progress on chloride ion transport in concrete structures both domestically and internationally, introduces the latest research results on chloride ion transport mechanisms, transport laws, prediction methods, and points out the limitations and future research directions in existing research on chloride ion transport and prediction in concrete structures.
