Anti-corrosion building concrete

Abstract

The invention relates to anti-corrosion building concrete. The anti-corrosion building concrete comprises cement and an admixture, and further comprises a preservative and a dispersing agent, wherein the preservative mainly comprises aluminum silicate and barium hydroxide; the dispersing agent is mainly silica fume; the preservative is 10%-15% of the total weight of the concrete; the dispersing agent is 10%-15% of the total weight of the concrete. The anti-corrosion building concrete disclosed by the invention has good anti-corrosion anti-erosion performances; the dispersing agent which is composed of methyl cellulose and silica fume can be used for uniformly dispersing the preservative, so that the anti-corrosion effect of the preservative can be brought into player better; isobutyl triethoxy silane is penetrated into the concrete to generate chemical reaction with air exposed in an acid or alkali environment as well as water molecules in a substrate, so that a water-repellent treatment layer is formed, and therefore, the water is restrained from entering the substrate.

Description

[0001] technical field [0002] The invention relates to the technical field of building materials, in particular to anti-corrosion building concrete. [0003] Background technique [0004] Building materials are the material basis of construction engineering, and various materials are needed in the construction of buildings from the main structure to decoration. Concrete is a durable material. Its main components include cement, admixtures and aggregates. It is hardened after adding water and stirring. It has the advantages of simple process and fire resistance, but it is essentially a non-uniform porous material. Under the erosion of carbon dioxide, water, chloride ion, sulfate and other media, it is inevitable to be corroded by external factors, the concrete will be destroyed at an accelerated rate, and the service life will be greatly shortened. Contents of the invention [0005] The technical problem to be solved in the present invention is: overcome the deficiency ...
