Self-repairing material for concrete cracks as well as preparation method and use method of self-repairing material
The invention discloses a self-repairing material for concrete cracks as well as a preparation method and a use method thereof, and belongs to the technical field of preparation of concrete crack repairing materials. According to the material, high-activity inorganic silicon dioxide and an organic ammonia compound are added on the basis of fatty acid and other acids. The problem that plenty of manpower and material resources are needed for repairing after concrete cracks are generated is solved, the concrete has the self-repairing capacity by means of the repeated repairing function of the concrete crack repairing device, and link and resource waste is reduced. According to the principle, water permeates after concrete cracks are generated, active chemical substances in the concrete cracks are combined with hydration products in cement to generate water-insoluble crystals, capillary pores and micro cracks in the concrete can be filled with the crystals, the purpose of self-healing repairing is achieved, and the purpose of self-healing repairing is achieved when the cracks (smaller than or equal to 0.8 mm) generated through repairing are blocked.
本发明公开了一种混凝土裂缝的自修复材料、制备和使用方法，属于混凝土裂缝修复材料的制备技术领域。该材料中在脂肪酸及其他酸类的基础上加入高活性无机二氧化硅及有机氨复合物。解决了混凝土裂缝产生后，需要大量人力物力修补的困境，依靠本发明本身具备的多次修复功能，使混凝土具备自修复能力，减少环节及资源浪费。其原理是当混凝土裂缝产生后有水渗入，其中活性化学物质与水泥中的水化产物结合生成不溶于水的结晶体，可以填塞混凝土中的毛细孔和微细裂缝，达到自愈修复的目的，堵塞修复产生的裂缝（≤0.8mm），达到自愈修复的目的。
