Abstract

The invention provides an anti-corrosion concrete preparation method and relates to the field of concrete. The method utilizes 260 to 300 parts by weight of cement, 500 to 600 parts by weight of broken stones, 700 to 800 parts by weight of sand, 70 to 100 parts by weight of mineral powder, 50 to 70 parts by weight of fly ash, 80 to 100 parts by weight of a water reducing agent, 20 to 30 parts by weight of an epoxy resin coating, 20 to 30 parts by weight of inorganic zinc-rich paint, 150 to 200 parts by weight of water, 40 to 60 parts by weight of a gelling agent, 30 to 50 parts by weight of acrylamide gel, 20 to 40 parts by weight of high-density polyethylene, 30 to 50 parts by weight of an acrylic adhesive, 10 to 30 parts by weight of an antioxidant DLTP, 10 to 30 parts by weight of an antioxidant TPP and 20 to 30 parts by weight of carbon fibers. The epoxy resin coating and inorganic zinc-rich paint are sprayed to the surface of a reinforcing steel bar and form a protective film forprotecting the steel bar so that the steel bar surface has a strong anti-corrosion function. Under combination of acrylamide base and high-density polyethylene, the concrete has high waterproof performances and prevents water from penetrating into the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete production method with anti-corrosion capability. Background technique [0002] At present, the corrosion resistance of steel bars inside concrete is weak. When water penetrates into the concrete, it is easy to loosen the concrete and produce micropores, so that the corrosive medium enters the interior of the concrete, contacts with the internal steel bars, corrodes the steel bars, and reduces the strength of the steel bars. At the same time, water seeps into the concrete After the concrete is inside, make the inside of the concrete moist, and the internal steel bars will be easily corroded in a humid environment, resulting in a decrease in the strength of the concrete. Contents of the invention [0003] The invention provides a concrete with reasonable and novel structure, small volume and anti-corrosion ability. [0004] Technical solutions [0005] In order to ...
