用三要素综合评估混凝土中钢筋腐蚀状态

Corrosion Severity Assessment of Reinforcing Steel in Concrete by Using Three Electrochemical Factors

    摘要
  • 摘要: 介绍了一种判断钢筋腐蚀状况的方法——EIR法.该方法采用钢筋自然腐蚀电位、腐蚀电流密度、混凝土电阻率三个电化学要素判断钢筋腐蚀状况,解决了美国ASTMC876-91标准等单一要素判别方法判断钢筋腐蚀的缺陷,并准确地对北京某一重点工程大楼部分区域混凝土中钢筋的腐蚀状态进行了评估.

     

    Abstract: A method named EIR Method is introduced, which makes use of corrosion potential, corrosion current and concrete resistivity to assess the corrosion severity of reinforcing steel. It ameliorates the veracity of some standards such as ASTM C 876-91, and has been successfully used to estimate the corrosion severity of reinforcing steel in concrete in a famous building in Beijing.
