本文介紹國內鋼鐵廠的鋼筋混凝土設施，其結構劣化調查之結果，並針對各項RC 結構設施進行劣化原因分析，並提出改善建議或防蝕措施。此外，從RC 結構的設計規劃、施工、使用維護管理等三階段，探討各階段的防蝕對策與最適的方法。期能藉此增進國人對RC 結構劣化現象的瞭解，並喚起從事RC 結構設計、施工及維護管理者，對鋼筋防蝕應用的重視。

This paper presents the results compiled from a survey on deteriorated reinforced concrete facilities in the iron and steel industry in Taiwan. Emphases are placed on the causes of deterioration for each individual reinforced concrete facility. Maintenance techniques or practices aimed at corrosion prevention are then recommended. Moreover, advanced corrosion prevention concepts and techniques for designs, construction and maintenances of reinforced concrete facilities are discussed.
