摘要
分析了混凝土横向裂缝处钢筋的腐蚀机理,通过背对背的小梁试件对其进行了试验研究,得出了裂缝宽度、混凝土保护层厚度、混凝土水灰比对混凝土横向裂缝处钢筋腐蚀速度的影响规律。
The electrochemical corrosion mechanism of rebar located in the transverse crack in concrete was made, the corrosion experiments under chloride-diffusion and carbonization circumstance were done, at last, some conclusions were drawn about the influences of crack width, concrete cover depth and water/cement ratio on the corrosion-rate of rebar in concrete.
