非饱和混凝土氯离子传输模型研究综述

摘要

In the unsaturated chloride environment,when concrete structures subjected to alternating wet and dry,steel corrosion is often the most serious.It summarized the transmission mechanism of chloride ion in concrete under unsaturated state,focusing on the analysis presented in the unsaturated concrete chloride ion transport model,and pointed out the advantages and disadvantages and applicability of each transmission model,and provided the proference for the establishment of the perfect transmission model of chloride ions in concrete under unsaturated state.%在非饱和氯盐侵蚀环境中，混凝土结构受到干湿交替作用其钢筋锈蚀往往较为严重。主要对非饱和状态下混凝土中氯离子的传输机理进行了归纳总结，重点分析介绍了非饱和混凝土中氯离子传输模型，并指出各传输模型的优缺点和适用性，为建立完善的非饱和状态下混凝土中氯离子传输模型提供参考。
