Corrosion Severity Assessment of Reinforcing Steel in Concrete by Using Three Electrochemical Factors
-
摘要: 介紹了一種判斷鋼筋腐蝕狀況的方法——EIR法.該方法采用鋼筋自然腐蝕電位、腐蝕電流密度、混凝土電阻率三個電化學要素判斷鋼筋腐蝕狀況,解決了美國ASTMC876-91標準等單一要素判別方法判斷鋼筋腐蝕的缺陷,并準確地對北京某一重點工程大樓部分區域混凝土中鋼筋的腐蝕狀態進行了評估.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.
