摘 要: 钢筋锈蚀是影响混凝土耐久性的首要因素,基于目前国内外对钢筋锈蚀的研究现状,对比工程实际中箍筋锈蚀相对纵筋锈蚀程度更严重的现象,从箍筋锈蚀机理、混凝土材料自身特点及正常使用条件下混凝土构件的带裂缝工作状态出发,分析了以上各因素对箍筋锈蚀速度的影响,为今后进一步研究箍筋锈蚀问题提供参考。 The corrosion of steel bar is the primary factor affecting the durability of reinforced concrete structures.Based on the current status of research on the corrosion of steel bar at home and abroad,compared with the practical phenomenon that the corrosion degree of the stirrup is more serious than the longitudinal bars,through the mechanism of stirrup corrosion,the material characteristics of reinforced concrete and the concrete elements working with cracks in normal conditions,in this paper,the corrosion rate of the stirrup were investigated.It provides a reference for further study on stirrup corrosion in the furure.
