The corrosion behavior of steel embedded in concrete is significantly affected quality, existance of the crack, the invasion of determinate element, such as chloride-ion, and external loading. In this research, based on the corrosion mechanism of steel in concrete, and induce reinforce concrete failure, We also study on the anti-corrosion technology of steel in concrete. The select of anti-corrosion material and construction management will be disscussed in this paper. We hope to prevent steel corrosion and to prove structure safety.
