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.
