Abstract:
Corrosion of steel bars in reinforced concrete structures is a problem that is demanding increasing attention worldwide. In Peru, steel-in-concrete corrosion has not been unusual in structures in areas near the sea and in offshore structures. What is new is corrosion of structures in climates that are not particularly aggressive. A case in point is a structure about three miles from the sea in the capital city of Lima, where climatic conditions are mild: 65 percent average relative humidity and 15 to 20 C (59 to 77 F) extreme yearly temperatures. This article reports on the causes of corrosion and describes the procedures employed to repair the structure and to stop the corrosion process.
