High-performance concrete with high seawater corrosion resistance and preparation method thereof

The invention discloses high-performance concrete with high seawater corrosion resistance and a preparation method of the high-performance concrete. The high-performance concrete is prepared from the following raw materials in parts by weight: 310 to 450 kg of aluminoferrite cement, 160 to 175 kg of water, 1080 to 1200 kg of gravel, 620 to 720 kg of machine-made sand, 60 to 120 kg of fly ash and 6 to 9 kg of a water reducing agent. Wherein the water reducing agent is prepared by mixing a viscosity-reducing slow-release polycarboxylic acid mother solution, a coagulation regulating component, an air entraining agent and a defoaming agent according to a mass ratio of (15 to 20): (3 to 7): (0.10 to 0.30): (0.02 to 0.06). The concrete prepared by the invention has good construction performance, and solves the technical problems of early crack control of the aluminoferrite cement in mass concrete construction, too fast initial setting time after pouring and inconvenient construction; the concrete has good harmful i
