Abstract:
The corrosion-induced deterioration of a 25-year-old reinforced concrete building in Kuwait was investigated to determine the extent and causes of the deterioration. The investigative techniques employed involved visual inspection of the structure, nondestructive testing, and laboratory testing and analysis of material samples removed from the structure. These techniques provided information on the nature of the service environment and its role in promoting corrosion of steel reinforcement in the structure. Both chloride-induced corrosion and carbonation-induced corrosion were found to occur, with extensive loss of steel section in some concrete elements. The information gained from such an investigation of corrosion damage is necessary for the selection of appropriate repair schemes.
