Establishment of repairing method and repair effect verificatio ntechnology for cracks with movement occurred in building walls

本研究旨在对钢筋混凝土结构发生运动时施工裂缝修补方法的选择技术进行合理化研究。为了选择合理的裂缝修复材料，进行了一些试验，不仅要评估修复后的立即修复效果（初始性能），而且要评估其耐久性。本研究对目前广泛使用的裂纹修复材料进行了提取，从而清楚地表明，每种修复材料的单质变化和促进降解外力作用下修复效果的下降是不同的，表明了评估修复效果耐久性的重要性。提出了裂缝浇筑法施工评价及修复效果的检测技术。

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.
