Concrete self-repairing material and use method thereof
The invention belongs to the technical field of concrete, and particularly relates to a concrete self-repairing material and a use method thereof. The concrete self-repairing material comprises a binder serving as a repairing liquid and a hollow glass tube serving as a carrier, wherein the binder is one or more of a polyurethane binder, an epoxy resin binder and an acrylic resin binder. A self-repairing material with a repairing function is pre-embedded in a concrete matrix, and when the matrix generates cracks due to stress, the repairing material flows out under the action of external force and is released to concrete cracks to fill the cracks, so that the crack self-repairing effect is achieved.
本发明属于混凝土技术领域，具体涉及一种混凝土自修复材料及其使用方法。该混凝土自修复材料包括作为修复液的粘结剂和作为载体的空心玻璃管，粘结剂为聚氨脂类粘结剂、环氧树脂粘结剂、丙烯酸树脂粘结剂中的一种或多种。在混凝土基体中预埋入带有修复功能的自修复材料，在基体因受力产生裂纹时，修复材料因外力的作用下流出，释放到混凝土裂纹处，填充裂纹，达到裂纹自修复的效果。
