Concrete crack self-healing agent and preparation method thereof
The invention provides a concrete crack self-healing agent and a preparation method thereof , and the crack self-healing agent is prepared from the following components in parts by weight: 100 to 200 parts of cement, 250 to 350 parts of sand, 100 to 150 parts of water, 20 to 30 parts of basophilic bacillus, 15 to 25 parts of a sol active agent, 8 to 10 parts of water-soluble calcium salt, 3 to 5 parts of a nutrient substance, 0.5 to 1.5 parts of a water repellent and 1 to 2 parts of a complexing agent. The self-healing agent for the concrete cracks can enable a cementing material, microorganisms and a self-repairing material assisting in mineralization of the microorganisms to penetrate into the deep parts of the concrete cracks, can effectively seal the existing cracks, can self-heal new cracks in the process that the microorganisms generate calcium carbonate when secondary cracking occurs, the method has remarkable engineering significance in improving the repairing efficiency of concrete cracks and improving the durability of a repaired structure.
本发明提供一种混凝土的裂缝自愈合剂及其制备方法，所述裂缝自愈合剂以重量份数计，包括：水泥100‑200份、砂250‑350份、水100‑150份、嗜碱性芽孢杆菌20‑30份、溶胶活性剂15‑25份、水溶性钙盐8‑10份、营养物质3‑5份、憎水剂0.5‑1.5份和络合剂1‑2份。本发明提供的混凝土的裂缝自愈合剂能够将胶凝材料、微生物及辅助微生物矿化的自修复材料渗透到混凝土裂缝深处，不仅可以有效封闭既有裂缝，且在发生二次开裂时微生物生成碳酸钙的过程可以自修复新生裂缝，对于提高混凝土裂缝修补效率，提高修补结构的耐久性具有显著的工程意义。
