The invention discloses self-corrosion-resistant concrete. The self-corrosion-resistant concrete is prepared from the following raw materials in parts by weight: 180-300 parts of concrete, 50-120 parts of fly ash, 80-120 parts of mineral powder, 20-35 parts of highly-active silicon aluminate, 4-10 parts of a self-healing agent, 600-900 parts of river sand, 800-1200 parts of gravel, 120-170 parts of water and 3-6 parts of a water reducing agent, wherein the highly-active silicon aluminate is prepared by grinding kaolin and then calcining at 600-800 DEG C for 2-4h; the sum of the SiO2 content and the Al2O3 content of the highly-active silicon aluminate is greater than 90%; the specific surface area of the highly-active silicon aluminate is greater than or equal to 10,000 m<2>/kg. The self-corrosion-resistant concrete provided by the invention has the characteristics of good workability, high strength, high resistance to chloride salt and sulfate corrosion, high volume stability, crack self-healing and the like; during application to a marine environment and other severe erosive environments, compared with conventional high-performance concrete, the self-corrosion-resistant concrete provided by the invention has obvious advantages.
