Preparation method of concrete repairing bacterial liquid

Abstract

The invention discloses a preparation method of a concrete repairing bacterial liquid. The preparation method comprises the following steps: step I, performing culturing; step II, performing rejuvenation; step III, performing expanding; and step VI, performing cooking. In the step I, coriolis bacillus is put into an appropriate amount of liquid culture medium, and then the liquid culture medium isput into a constant-temperature culture shaking table. According to the invention, the concrete repairing bacterial liquid is prepared, and the mineralization effect of calcium ion precipitation is induced by heterotrophic microorganisms, so that the internal structure of concrete is improved, the quality defect of the concrete is overcome, the physical and chemical properties of the concrete arechanged, the strength and quality of the concrete are improved, and the service life of a concrete building is prolonged; a traditional steel reinforcing and sand filling grouting manner is replacedwith a microorganism repairing manner, the repairing effect of the concrete is improved, operation is rapid, use is convenient, the labor intensity of personnel is low, the resource loss amount is low, the repairing cost of the concrete is reduced, and the requirement for large-batch repairing of the concrete is met.

Description

technical field [0001] The invention relates to the technical field of concrete repair, in particular to a method for preparing a concrete repair bacterial solution. Background technique [0002] Concrete refers to artificial stone prepared by cementitious materials, coarse and fine aggregates, water and other admixtures in appropriate proportions. Ordinary concrete is made of cement as the cementitious material, sand and stone as the aggregate, and mixed with water. It is widely used in civil engineering. Concrete itself is a heterogeneous, porous, heterogeneous and discontinuous body with internal primary defects. In addition, due to quality fluctuations of all raw materials in production, measurement errors, and insufficient mixing, it will cause layering, segregation, bleeding, dryness, and hardening. The characteristics of poor workability and improper construction operations such as formwork and steel bar system deviation during construction, warehousing, vibrating, f...

Problems solved by technology

[0003] However, the traditional concrete steel reinforcement method not only fails to improve the internal structure of concrete, but also affects the stress system of concrete. It also requires a certain amount of additional steel resources, which is high in cost and poor in effect, and cannot meet the needs of large quantities of concrete repairs. Although the sand grouting method can improve the internal structure of the concrete and repair the quality defects of the concrete, the concrete needs to be manually chiseled and rinsed with water.
