Crack repair effects of injection method using organic/inorganic composite materials

Abstract

In this research, properties of new crack repair materials using organic and inorganic composite (OAI) materials were investigated under various crack conditions. Especially, this study aims to develop new composites repair materials as needed to follow the crack and its repair method. Crack repair methods such as injection method and surface treatment repair method using self-healing capability for the practical industrial application were examined in comparison with normal crack repair method as the epoxy injection. From these results, it was confirmed that the sealing and injection effects through the cracks from field tests could be improved by OAI.
