摘要：
Corrosion of reinforcement induced by chloride corrosion is the primary cause of durability deterioration to reinforced concrete structures in coastal or de⁃icing salt environments. Chloride binding is one of the most economical and the most effective measures to enhance the anti⁃ chloride⁃corrosion ability of reinforced concrete structures. Therefore, a large number of references have extensively studied the mechanism, performance, and influence factors of chloride binding in Portland cement (PC). However, It's lack of systematic summary and discussion on chloride binding of PC. Herein, this paper presents a comprehensive and systematic review of the research progress in the mechanism and influence factors of chloride binding of PC. Firstly, two types of chloride binding mechanisms are detailedly introduced. Secondly, the influence factors of chloride binding performance are analyzed. Thirdly, the contribution of chloride binding is defined, and the contribution change under different factors is discussed. Finally, the main challenges in the field of chloride binding of PC are summarized. These contribute to a deeper understanding of the mechanism and influence factors of chloride binding of PC, and provide references for the prediction of service life and the durability improvement of reinforced concrete structures. © 2024 Cailiao Daobaoshe/ Materials Review.
