Problems solved by technology

[0002] Concrete is a durable material, but it is essentially a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions, sulfate and other media, it is inevitably corroded by external factors. Concrete It will accelerate the damage and greatly shorten the service life
The existing concrete has weak corrosion resistance and cannot effectively resist the erosion of external corrosive substances

Abstract

The invention discloses anti-corrosion concrete. The anti-corrosion concrete is prepared from the following raw materials in parts by mass: 50 to 60 parts of cement, 5 to 9 parts of diisopropanolamine, 7 to 9 parts of calcium lignosulphonate, 6 to 8 parts of calcium nitrate, 15 to 20 parts of urea formaldehyde resin, 4 to 7 parts of monoethanolamine, 8 to 11 parts of acrylic emulsion, 7 to 12 parts of calcium carbonate, 8 to 10 parts of fiberglass, 6 to 8 parts of silicon dioxide powder, 3 to 6 parts of sodium perborate, 14 to 17 parts of pulverized fuel ash and 16 to 18 parts of haycite. The anti-corrosion concrete disclosed by the invention is strong in corrosion resistance, is capable of resisting corrosion of external corrosive articles, and is good in anti-freezing effect and small in cracking.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a corrosion-resistant concrete. Background technique [0002] Concrete is a durable material, but it is essentially a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions, sulfate and other media, it is inevitably corroded by external factors. Concrete It will accelerate the damage and greatly shorten the service life. The existing concrete has weak corrosion resistance and cannot effectively resist the erosion of external corrosive substances. Contents of the invention [0003] In order to solve the above problems, the present invention provides a corrosion-resistant concrete with strong corrosion resistance, effective resistance to external corrosive substances, good antifreeze effect and small cracking. [0004] The technical solution adopted by the present invention to solve the above technical problems is: a corrosion-resistant concre...
