摘　　要：氯离子侵蚀是滨海或除冰盐环境下钢筋混凝土结构耐久性劣化的首要原因。氯离子固化是提升钢筋混凝土结构抗氯离子侵蚀性能最为经济有效的手段之一。因此,大量文献对硅酸盐水泥(PC)氯离子固化机理、固化性能、影响因素等进行了广泛研究。然而,仍缺乏PC氯离子固化方面的系统性总结论述。因此,本文对PC氯离子固化机理及影响因素的研究进展进行了全面系统综述。首先详细介绍了两类氯离子固化机理;其次分析了氯离子固化性能影响因素;然后定义了氯离子固化贡献度并讨论了不同因素影响下的贡献度变化;最后概述了PC氯离子固化领域面临的主要挑战。本文有助于深化理解PC氯离子固化机理及影响因素,为钢筋混凝土结构寿命预测及耐久性提升提供参考。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.
