The invention relates to the technical field of microbial concrete materials, and discloses a concrete crack repair method based on anaerobic microorganisms. First, a plurality of concrete components are fabricated, and repair agents such as bacterial spores and calcium salts are added during the concrete mixing process to prepare After completion, the concrete components are put into water, and the concrete cracks in the water through the pressure test, so that the test can be carried out on the concrete cracks, and the concrete cracks are sealed with special sealing components, so as to facilitate the injection of various solvents into the concrete cracks. Secondly, it is necessary to cultivate and extract the anaerobic bacteria Proteus and make a repairing agent; in the present invention, the calcium carbonate is precipitated by the iron salt reduction reaction that the Proteus produces urease and acetate and the ferric hydroxide solvent. Furthermore, the anaerobic microorganism catalyzes the precipitation of calcium carbonate to achieve the effect of improving the repair of concrete cracks, and the compounds produced by the chemical reaction are harmless to the human body and the environment. |
