Concrete crack depth self-repairing method based on microorganisms
The invention provides a concrete crack depth self-repairing method based on microorganisms. Comprising the following steps: attaching microbial spores, a nutritional agent and a mineralizing agent to the surface of a porous carrier; microbial spores, a nutritional agent and a mineralizing agent are implanted into the concrete through a porous carrier, and deep self-repairing from the outside to the inside is completed under proper conditions after the concrete is cracked. According to the method, alkali-resistant urease-producing aerobic denitrifying bacteria spores, a nutritional agent and a mineralizing agent are attached to the surface of a porous carrier, the carrier is used for replacing part of aggregate to be added into concrete, concrete cracking is responded, and self-repairing of cracks is completed in a proper mineralization mode. According to the method, the alkali-resistant urease-producing aerobic denitrifying bacteria spores, the nutritional agent and the mineralizing agent are implanted into the concrete, the repairing requirements under different oxygen content conditions can be met, concrete cracks are deeply repaired from the outside to the inside, the application range of the concrete microorganism self-repairing technology is greatly widened, and the repairing efficiency of the concrete microorganism self-repairing technology is greatly improved.
本发明提供了一种基于微生物的混凝土裂缝深度自修复方法；包括以下步骤：将微生物芽孢、营养剂和矿化剂附着于多孔载体表面；通过多孔载体将微生物芽孢、营养剂和矿化剂植入混凝土内部，混凝土开裂后将在适宜的条件下完成由表及里的深度自修复。本发明方法将耐碱型产脲酶好氧反硝化细菌芽孢、营养剂和矿化剂附着于多孔载体表面，用载体替代部分骨料加入混凝土，对混凝土开裂进行响应，通过适当的成矿方式完成裂缝的自修复。本发明利用将耐碱型产脲酶好氧反硝化细菌芽孢、营养剂和矿化剂植入混凝土，能够满足不同氧含量条件下的修复需求，对混凝土裂缝进行由表及里深度修复，极大地拓展了混凝土微生物自修复技术的应用范围和修复效率。
