摘要
氯离子引起的钢筋腐蚀是造成海洋环境下混凝土结构性能劣化的主要原因.氯盐环境下混凝土结构的使用寿命预测和寿命周期经济评价已成为目前研究的重点.文中讨论了混凝土结构使用寿命的定义,较为系统地总结和评述了近年来有关氯盐环境下混凝土结构使用寿命评价的研究进展,并提出了需要进一步研究的问题.
Chloride-induced corrosion of reinforcing bars is the leading cause of deterioration of reinforced concrete structures in marine environment. At the present time, the service life prediction and life-cycle cost analysis of reinforced concrete structures in chloride environment have become the priority research area. The definition of service life of reinforced concrete is discussed, and the recent development of service life evaluation of reinforced concrete structures in chloride environment is systematically summarized and reviewed. Finally, the direction for further work and problems to be solved are presented.
