Concrete pavement apparent damage repairing and efficient curing material and preparation method thereof
The invention discloses a concrete pavement apparent damage repairing and efficient curing material and a preparation method thereof, and belongs to the technical field of self-repairing concrete. The concrete pavement apparent damage repairing and efficient curing material is prepared from the following raw materials: Portland cement, coarse aggregate, fine aggregate, a water reducing agent, water, high-tensile-strength fibers and efficient curing microcapsules, wherein the wall material of the efficient curing microcapsule is active silicate-urea resin, and the core material of the efficient curing microcapsule is basophilic bacillus spores and calcium lactate. By adding the microcapsules containing the basophilic bacillus spores and the calcium lactate into the concrete, the apparent defects occurring in the concrete paving process can be repaired. Meanwhile, the structure of the microcapsule is designed, the shell of the microcapsule is cured, basophilic bacillus spores in the microcapsule are better protected, and when the prepared concrete cracks again in the later period, alcohol-containing liquid is sprayed on the surface of the cracks, the core material in the microcapsule is rapidly released, and the rapid repairing effect is achieved.
本发明公开了一种混凝土铺装表观损伤修复与高效固化材料及其制备方法，属于自修复混凝土技术领域。所述混凝土铺装表观损伤修复与高效固化材料的原料包括：硅酸盐水泥、粗骨料、细骨料、减水剂、水、高抗拉强度纤维和高效固化微胶囊；其中高效固化微胶囊的壁材为活性硅酸盐‑脲醛树脂，芯材为嗜碱性芽孢杆菌孢子和乳酸钙。通过在混凝土中加入含有嗜碱性芽孢杆菌孢子和乳酸钙的微胶囊，能够修复混凝土铺装过程中出现的表观缺陷。同时，通过对微胶囊的结构进行设计，固化微胶囊外壳，更好的保护微胶囊中的嗜碱性芽孢杆菌孢子，当制备的混凝土后期再出现裂缝时，在裂缝表面喷洒含醇液体，快速释放微胶囊中的芯材，达到快速修复的效果。
