Problems solved by technology

As far as concrete materials are concerned, although the total energy consumption per unit of production is very low, the huge amount used and the overall low level of technology put a lot of pressure on resources, energy and the environment as a whole
The service environment of concrete structures is often very complicated. The durability of the current concrete cannot meet the requirements of the society, and further research and development are needed

Abstract

The invention discloses a high-durability concrete which comprises the following raw materials: cement, river sand, macadam, water, fly ash, nano microbead, natural zeolite micropowder, aluminum oxide, sodium sulfate, diethanolamine, sodium hydroxide, methyl trichlorosilane, ethanol, an air entraining agent, a lignosulfonate water reducing agent, polyvinyl alcohol, mixed fiber, sodium nitrate and polyvinylpyrrolidone. The mixed fiber is the combination of carbon fiber, steel fiber, polypropylene fiber and polyvinyl alcohol fiber in a weight ratio of 1:(2-5):(3-7):(3-6). The high-durability concrete has the advantages of high strength, favorable water impermeability, favorable freezing resistance and favorable durability, and has long service life when being applied to hydrotechnics, harbors, roads and other projects.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-durability concrete. Background technique [0002] Concrete has also become the material of choice for roads, dams, and bridges, as industrial development and urbanization accelerate. With the proposal of high-performance concrete, the durability of concrete has attracted more and more attention from all aspects. The durability of concrete refers to the resistance of the concrete structure to climate, chemical corrosion, physical action or any other damage process. Its safety, usability and appearance. As far as concrete materials are concerned, although the total energy consumption per unit of production is very low, the huge consumption and the overall low technical level put a lot of pressure on resources, energy and the environment as a whole. The service environment of concrete structures is often very complicated. The durability of the current concrete cannot mee...
