This paper presents a probabilistic analysis of almost 700 potential and polarization resistance measurements of reinforcing steel embedded in 15 types of mortars of different nature and chloride contamination levels exposed to controlled conditions of temperature and relative humidity. Besides indicating that the ASTM C876 standard can be a robust and reliable commissioning tool for strategic assets in terms of effectiveness of reinforcing steel passivation, results show that the polarization resistance values follow different probability density functions at different potential levels, which means they do correspond to distinct interfacial processes.

重新审视ASTM C876钢筋腐蚀标准：关于不同水泥砂浆固化过程中腐蚀电位和极化强度之间的关系

本文提供了对嵌入在15种不同性质和暴露于受控温度和相对湿度条件下的氯化物污染程度的砂浆中的钢筋的近700个电位和极化电阻测量值的概率分析。除了表明ASTM C876标准在增强钢钝化的有效性方面可以成为战略资产的可靠可靠的调试工具外，结果还表明，极化电阻值在不同的电位水平下遵循不同的概率密度函数，这意味着它们确实对应于不同的界面过程。
