| Outline of Final Research Achievements |
The purpose of this study is to evaluate repairing effectiveness of concrete structures deteriorated due to Alkali Silica Reaction (ASR). Modified RILEM AAR-4 Method was proposed. This method is expected to decrease alkali leaching and drying. It is applied to accelerated test of concrete repaired with surface penetrant agent. As a result, it was observed that repairing effectiveness, in some cases, was not found. The reason seemed that water can not be released in the testing container.
