| Outline of Final Research Achievements |
It is serious and important problem on maintenance of concrete structure deteriorated by
Alkali-silica reaction (ASR) and chloride induced corrosion. On the occurrence of the combined deterioration of concrete structure due to ASR and chloride induced corrosion, the evolution of degradation of concrete structure is not cleared. In this study, the main scope was forced on the permeation of chloride ion and the corrosion in concrete structure affected by the combined deterioration. As the results, it is indicated that cracks caused by the expansion due to ASR may promote the degradation due to chloride induced corrosion.
