CRACK REPAIRING MATERIAL COMPOSITION AND CRACK REPAIRING METHOD
To provide a crack repairing material composition and a crack repairing method that can enhance the durability of structures with metal reinforcement.SOLUTION: A repair method for repairing cracks in structures with metal reinforcement includes a step to prepare first and second crack repairing material compositions that contain epoxy resin and a rust preventive agent and have different viscosities when prepared, and a step to inject the first crack repairing material composition 31 into the cracks of the structure from the surface of the structure toward the back and then inject the second crack repairing material composition. The first crack repairing material composition has a lower viscosity than the second crack repairing material composition, and the content rate of the rust preventive agent in the first crack repairing material composition is higher than the content rate of the rust preventive agent in the second crack repairing material composition.SELECTED DRAWING: Figure 5
【課題】金属補強材入りの構造物の耐久性を高めることができるひび割れ補修材組成物、およびひび割れ補修工法を提供する。【解決手段】金属補強材入り構造物のひび割れを補修する補修方法であって、前記補修方法は、エポキシ系樹脂と、防錆剤とを含有し、調製時の粘度が互いに異なる第１及び第２のひび割れ補修材組成物を用意するステップと、前記構造物のひび割れに該構造物の表面から奥に向かって、前記第１のひび割れ補修材組成物３１を注入し、その後で、前記第２のひび割れ補修材組成物を注入するステップと、を備え、前記第１のひび割れ補修材組成物は、前記第２のひび割れ補修材組成物よりも低い粘度を有し、前記第１のひび割れ補修材組成物における前記防錆剤の含有率は、前記第２のひび割れ補修材組成物における前記防錆剤の含有率より高い、補修方法。【選択図】図５
