要旨 |
Many concrete structures are currently affected by the alkali-silica reaction (ASR). In addition, the de-icing salts have sprayed in the winter to ensure the safety of vehicles. The in-situ survey was conducted to comprehend the steel corrosion in the abutments affected by the combined deterioration of ASR and de-icing salts. The result indicated the influence of water leakage included de-icing salts become a considerable cause of corrosion in ASR deteriorated structures. Furthermore, the evaluation of corrosion risk can carry out based on the surface moisture of concrete and chloride ions contents. |
