| Research Abstract |
This research aims at rationalization of the selecting technique of a crack repair method of construction with the movement occurred in RC structure. In order to select rational crack repair material, some experiments were performed paying attention to the necessity for evaluating not only the repair effect immediately after repair (initial performance) but its durability. In this research, the material currently used widely as crack repair material was extracted, consequently, it showed clearly that the change of a repair material simple substance and the fall of the repair effect by promotion degradation external force differ from each other for every repair material, and the importance of evaluating the durability of the repair effect was shown. Moreover, the inspection technique of evaluation of construction and the repair effect in a crack pouring method of construction were proposed.
