| Research Abstract |
In this study, innovative repair methods based on crack self-healing technologies using cementitious materials were suggested in order to prevent water leakage in civil infrastructure such as slab, tunnel and water-retaining structure. Especially, this study aims to develop new inorganic repair materials as needed to follow the crack and its repair methods. Crack repair methods such as Coating Method (CM), Drilling & Filling Method (DFM) and Coating and DF Method (CDFM) for the practical industrial application were examined in comparison with normal crack repair method without self-healing capability. From these results, it was confirmed that the sealing effects of water leakage through the penetrating cracks from field tests could be improved by cementitious composite materials with self-healing capability.
