Anti-corrosion concrete

Abstract

The invention relates to the technical field of building materials, and particularly relates to anti-corrosion concrete, which comprises the following components in parts by weight: 200-250 parts of portland cement, 60-80 parts of a polymer emulsion, 10-30 parts of a film-forming additive, 5-10 parts of a dispersant, 20-40 parts of mineral powder, 8-15 parts of a rust inhibitor, 6-8 parts of an air entraining and water reducing agent, 100-150 parts of water, 5-10 parts of sodium silicate, 1.5-3.5 parts of potassium silicate, 10-15 parts of wear-resistant corundum filler particles, 3-8 parts of an antifreeze and 2-5 parts of an accelerator. The anti-corrosion has the beneficial effects that the wear-resistant corundum filler particles as a wear-resistant component is matched with the mineral powder and the antifreeze, so that the wear resistance and corrosion resistance are greatly enhanced, the cost is low, the use and maintenance are also very convenient, the service life of a building can be effectively prolonged, and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-corrosion concrete. Background technique [0002] At present, the protection of concrete structures often adopts many methods of coating materials on the outer surface of concrete. Among permeable materials, such as materials with sodium silicate as the main component, by coating or injecting silicon into waterproof and maintenance areas Sodium is the main component of the material to achieve the purpose of protecting the concrete structure. However, the material has problems such as fast reaction speed in concrete, poor permeability and easy wear and tear of the surface film formed because the main body is sodium monosilicate. [0003] On the other hand, as the concrete structure becomes more and more complex, some structural forms or special parts of the structure, such as vertical thin-walled structures such as the side walls of the concrete basement, etc.,...

Problems solved by technology

However, the material has problems such as fast reaction speed in concrete, poor permeability and formation of surface membranes that are easy to wear and tear due to the fact that the main body is sodium monosilicate.
