Abstract

The invention discloses anti-permeability anti-corrosion concrete. The anti-permeability anti-corrosion concrete is prepared from the following components: silicate cement, coarse sand, medium-coarse sand, broken stone, water, steel slag, siliceous iron tailing powder, plaster, high calcium ash, ganister sand, vitrified microspheres, polycarboxylic water reducer, sodium molybdate, sodium nitrite, stannous chloride, ultrafine natural zeolite powder, hybrid fibres, an air entraining agent, urea and triethanolamine. According to the anti-permeability anti-corrosion concrete disclosed by the invention, the components are reasonable and act synergistically; the anti-permeability anti-corrosion concrete has high strength and high durability, such as freezing resistance, permeability resistance and corrosion resistance, and also has the advantage of preventing noise.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an anti-seepage and anti-corrosion concrete. Background technique [0002] Concrete is the most used building material today, and high-performance concrete represents the development direction of concrete technology. The wall column is an important part of the construction project. It bears the force of the entire construction project. As the main structure of the entire construction project, the quality requirements are very high. Concrete is one of the main construction materials in the wall construction process. The quality of the concrete material has a serious impact on the construction quality of the wall column, and affects the service life and use function of the project. At present, the impermeability and corrosion resistance of concrete still need to be improved. Contents of the invention [0003] Based on the technical problems existing in the background technolog...
