Self-repairing concrete and preparation method thereof
The invention provides self-repairing concrete, the concrete comprises cement, fine aggregate, coarse aggregate, water and microcapsules, the microcapsules contain a repairing agent, when the concrete cracks, the microcapsules are broken and release the repairing agent, and the repairing agent reacts with water and carbon dioxide to generate a filling substance to fill the cracks, so that the concrete structure is repaired. According to the concrete with the self-repairing capacity, the microcapsules containing the repairing agent are introduced into the concrete, when the concrete cracks, the microcapsules can be broken and release the repairing agent, and the repairing agent reacts with water and carbon dioxide to generate a filling substance to fill the cracks.
本发明提供了一种自修复混凝土，所述混凝土中包含水泥、细骨料、粗骨料、水和微胶囊，所述微胶囊内含有修复剂，当混凝土出现裂缝时，所述微胶囊破裂并释放修复剂，修复剂与水和二氧化碳反应生成填充物质，填补裂缝，从而修复混凝土结构。本发明提供了一种具有自修复能力的混凝土，通过在混凝土中引入包含修复剂的微胶囊，当混凝土出现裂缝时，这些微胶囊会破裂并释放修复剂，修复剂与水和二氧化碳反应生成填充物质，填补裂缝。
