Method for repairing concrete cracks by utilizing microorganisms
The invention discloses a method for repairing concrete cracks by utilizing microorganisms. The method comprises the following steps: step 1, dissolving; step 2, preparing materials; step 3, mixing; step 4, culturing; and step 5, repairing; wherein in the step 1, purchased bacillus freeze-dried powder is poured into a container and placed on a magnetic stirrer, then a proper amount of sterile normal saline is added, and the mixture is stirred and mixed evenly; and a microorganism mineralization repairing method is adopted, the concrete has the self-repairing capacity through the mineralization effect and the deposition effect of microorganisms, construction damage to the surface of the concrete in the repairing process is avoided, the structural stress of the concrete is ensured, the working reliability of the concrete is improved, auxiliary materials do not need to be adaptively processed on site, and cost is reduced. After being prepared in advance, the concrete can be directly applied on site, direct pollution and secondary pollution cannot be generated, the body health of constructors is guaranteed, and potential safety hazards of concrete buildings are eliminated.
本发明公开了一种利用微生物修复混凝土裂缝的方法，包括以下步骤：步骤一，溶解；步骤二，配料；步骤三，混合；步骤四，培养；步骤五，修复；其中在上述步骤一中，将购入的芽孢杆菌冻干粉倒入容器中，并放置在磁力搅拌机上，再加入适量的无菌生理盐水，搅拌混合均匀；该发明采用微生物矿化修复方法，利用微生物的矿化作用和沉积作用使混凝土具备了自我修复的能力，避免了修复过程中混凝土表面的施工损伤，确保了混凝土的结构应力，提高了混凝土的工作可靠性，且辅料无需现场适应性加工，提前制备后现场可直接施用，不会产生直接污染和二次污染，保障了施工人员的身体健康，消除了混凝土建筑物的安全隐患。
