The invention discloses anti-corrosive moistureproof concrete which is prepared from the following raw materials in parts by weight: 100-105 parts of common silicate cement, 35-40 parts of coal ash, 25-28 parts of iron ore powder, 8-15 parts of modified light calcium powder, 10-12 parts of flexible waterproof putty, 0.4-0.6 part of polyacrylamide, 0.8-1.0 part of an accelerant CZ, 3-4 parts of zinc chloride, 1-2 parts of zinc powder, 0.4-0.6 part of monopotassium phosphate, 0.5-0.6 part of calcium superphosphate, 0.3-0.5 part of nonylphenol polyoxyethylene ether, 1-3 parts of polyethylene wax and a proper amount of water. According to the concrete disclosed by the invention, the content of the flexible waterproof putty is increased, so that the concrete has the characteristics of light weight, flexibility and great hole; the modified light calcium powder is added, so that the concrete has the characteristics of light weight and corrosion and moisture resistance, and moreover, the concrete disclosed by the invention is simple in production process and good in processing property and can be recycled.
