RC結構物防蝕策略之研究

Study on the Anti-Corrosion of Reinforce Concrete Structural

混凝土中鋼筋的腐蝕行為決定於混凝土的品質，裂縫之形成，氯離子等有害物質入侵及外在載重之條件等。本研究係探討混凝土中鋼筋腐蝕機理，鋼筋混凝土主要劣化因素，及混凝土中鋼筋防蝕技術。分別就材料之選擇、施工技術及管理等加以剖析，俾有效抑制因鋼筋腐蝕造成之損壞，以確保結構物之安全。

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.
