电位、电阻率与钢筋腐蚀率关系研究

摘要

the half-cell potential and concrete resistivity can only qualitatively estimate the reinforcement corrosion in the concrete, but it can' t quantitative detect the corrosion level of steel rebar. Quantitative relationship of potential, resistivity and steel corrosion rate is researched with the help of these two methods. By studying and analysising on the concrete, the new evaluation based on potential method and resistivity is proposed, and tested in engineering practice.%半电池电位法、电阻率法都是定性地估计混凝土结构中钢筋腐蚀的状态,而不能定量检测钢筋腐蚀率.本文借助这两种方法来研究电位、电阻率与钢筋腐蚀率之间的定量关系.通过对混凝土构件进行的试验研究和分析总结,得出电位法、电阻率法新的评价方法,并在工程实践中得到验证.
