通过加速碳化的试验方法,分析了钢筋混凝土结构细微裂缝对碳化深度和钢筋锈蚀的影响,并得出结论.在微裂缝条件下,裂缝处的碳化深度是非裂缝处碳化深度的1.4~1.8倍,裂缝处的钢筋锈蚀严重.
Based on the accelerated carbonization test, this paper analyzes the influences of microcracks of reinforced concrete structure on carbonization depth and reinforcement corrosion, and draws the conclusion that, under the conditions of microcracks, the carbonization depth on cracks is 1. 4-1. 8 times that without cracks and the reinforcement corrosion on cracks is much grievous.
