摘　　要：宏电池腐蚀普遍存在于混凝土结构中,当其与微电池腐蚀共同作用时会显著加速混凝土结构劣化。近年来随着我国工程建设的不断推进,钢筋宏电池腐蚀引起的耐久性问题愈发突出,相应的防护需求日趋迫切。钢筋宏电池腐蚀影响因素众多,成因复杂,是腐蚀领域的一项难题与挑战。本综述探讨了宏电池腐蚀的机理,详细介绍了其影响因素,概述了混凝土中钢筋宏电池腐蚀研究进展,并展望了未来宏电池腐蚀的研究方向。Macrocell corrosion occurs in concrete structures universally, which accelerates the deterioration of concrete structures, when combined with microcell corrosion. In recent years, the durability problem caused by macrocell corrosion becomes more prominent with the advancement of engineering construction in China, thus demanding the corresponding protection. Nevertheless, there are many factors influencing the corrosion of microcell and their causes are relatively complicated, thus becoming a great challenge in the field of corrosion science and technology. This review offered an overview on the progress and prospects of macrocell corrosion of steel bars in concrete, including theory of the mechanism and influencing factors. In addition, the future research direction of macrocell corrosion was also discussed.
