Concrete crack repairing method based on anaerobic microorganisms
The invention relates to the technical field of microbial concrete materials, and discloses a concrete crack repairing method based on anaerobic microorganisms, which comprises the following steps: firstly, manufacturing a plurality of concrete members, adding repairing agents such as bacterial spores and calcium salt in the concrete mixing process, putting the concrete members into water after the concrete members are manufactured, and uniformly mixing the concrete members; concrete is cracked in water through a pressure effect test, so that the test can be performed at the concrete crack, a special sealing member is used for sealing the concrete crack so as to conveniently inject various solvents into the concrete crack, and then anaerobe proteusbacillus vulgaris needs to be cultured and extracted to prepare a repairing agent; according to the method, urease and acetate generated by proteusbacillus vulgaris are subjected to ferric salt reduction reaction with the ferric hydroxide solvent to promote calcium carbonate deposition, then calcium carbonate precipitation is catalyzed by anaerobes to achieve the effect of improving concrete crack repair, and compounds generated by chemical reaction are harmless to human bodies and the environment.
本发明涉及微生物混凝土材料技术领域，且公开了一种基于厌氧微生物的混凝土裂缝修复方法，首先对多个混凝土构件进行制作，在混凝土拌和的过程中加入细菌芽孢、钙盐等修复剂，制成后将混凝土构件放入水中，通过压力作用试验致使混凝土在水中开裂，从而在混凝土裂缝处可进行试验，使用特殊的封闭构件对混凝土裂缝处进行封闭处理，以方便于注射各溶剂进入混凝土裂缝中，其次还需要对厌氧菌变形杆菌进行培养与提取并制成修复剂；本发明中，通过变形杆菌产生脲酶和醋酸盐与氢氧化铁溶剂发生的铁盐还原反应促使碳酸钙沉积，进而通过厌氧微生物催化碳酸钙沉淀达到提升混凝土裂缝修复的效果，其化学反应所产生的化合物对人体与环境是无害的。
