タイトル：Analyzing rust constituent produced by mixture of chloride anti-freezing agent and corrosion inhibitor in existing bridge
This study shows the effect by using corrosion inhibitor based on analyzing rust constituent that was formed on existing bridge. Initially, the rust constituent analysis method on existing bridge by FT-IR was constructed. Based on this method, investigation of existing bridge was conducted. As a result of those analysis, it was suggested that the influence of chloride was eliminated by using corrosion inhibitor since β-FeOOH, which is formed in the presence of chloride, wasn’t detected. Therefore, it is considered that changing the anti-freezing agents from chloride to mixture of chloride and corrosion inhibitor is an effective way to reduce corrosion rate and it’ll lead to extend the life of the structures.
