Abstract

The invention relates to the technical field of concrete crack repairing, and further discloses a concrete crack repairing technology based on microorganisms. The technology involves the following rawmaterials by weight: 15-5 parts of calcium carbonate, 5-10 parts of bacillus sphaericus, 5-10 parts of bacillus lentus, 15-25 parts of calcium lactate, 3-9 parts of peptone, 5-12 parts of glutamate,10-18 parts of spore powder, 80-150 parts of an oxygen release agent, 6-18 parts of nutrient substance and 3-9 parts of an acid-base regulator. According to the concrete crack repairing technology based on the microorganisms, calcium carbonate deposition is driven through urea metabolism of bacillus sphaericus and bacillus lentus, and then calcium carbonate is rapidly catalyzed by the microorganisms for precipitation, so that the effect of improving the concrete crack repairing efficiency and quality is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete crack repair, in particular to a microorganism-based concrete crack repair technology. Background technique [0002] Concrete is referred to as concrete for short, which refers to the general designation of engineering composite materials that aggregate aggregates into a whole by cementitious materials. The term concrete usually refers to the use of cement as cementitious material, sand and stone as aggregates, and water ( It can contain admixtures and admixtures) in a certain proportion, and the cement concrete obtained by stirring is also called ordinary concrete, which is widely used in civil engineering. [0003] With the increasing use of concrete, the requirements for concrete repair technology have also increased. However, the existing concrete crack repair agents cannot precipitate calcium carbonate well, resulting in longer calcium carbonate crystal formation time, which greatly It affe...
