Abstract

The invention relates to the technical field of waterproof and anti-corrosion materials, and proposes an intelligent self-repairing waterproof and anti-corrosion compacting agent for concrete. 2 parts, 1-2 parts of potassium hydroxide, 1-2 parts of lithium hydroxide, 1-2 parts of bactericide, 1-2 parts of defoamer, 1-2 parts of emulsifier, 40-60 parts of deionized water. The waterproof and anti-corrosion compacting agent can be used as a concrete additive and can also be used as an outer coating material. The above technical solution solves the problem that the waterproof and anti-corrosion densifying agent in the prior art has poor densification effect and affects the mechanical properties of concrete.

Description

technical field [0001] The invention relates to the technical field of waterproof and anti-corrosion materials, in particular to an intelligent self-repairing waterproof and anti-corrosion compacting agent for concrete and a preparation method thereof. Background technique [0002] Concrete materials are widely used in bridges, tunnels, civil buildings and other projects. A common problem in concrete-based buildings is leakage. In addition, due to the shrinkage of concrete itself, and the change of external temperature will also affect the building, which will lead to cracks in concrete-based buildings. Concrete cracking will reduce the thickness of the protective layer of the concrete structure, resulting in accelerated transmission of aggressive media, air and water into the concrete structure, shortening the activation and corrosion time of the steel bars inside the concrete structure, and reducing the service life of the concrete structure. [0003] At present, the comm...
