| Abstract: | Based on the theory of corrosion electochemistry, predeterminate of steel corrosion in concrete under common air environment is established, and detailed method to determine model's parameters is given by using investigation results of engineerings. Formulas are corrected concerning with air relative humidity and ability to absorb oxygen for water membrane of steel surface. The author analyzes relationship of steel corrosion extent and concrete strength, cover thick, steel diameter and corrosion time. |
