| Outline of Final Research Achievements |
This study proposes repair and retrofitting method for damaged reinforced concrete member due to high temperature and detonation. Aggressive agent easily transports in concrete suffered from high temperature and this phenomenon obviously affects durability of concrete structure. Authors indicated that surface impregnation agent was effective as repair material to prevent moisture ingress into concrete. Nondestructive test method to evaluate damage of concrete due to detonation was also proposed and effectiveness of retrofitting method using aramid fiber was verified. Basic information for the repair and retrofitting methods for damaged concrete member due to high temperature and detonation were obtained though out this project.
