The application discloses a sulfate-resistant high-performance concrete and a preparation method thereof, comprising: the following mass ratios of main ingredients: 150-210 parts of cement, 10-30 parts of silica fume, 5-10 parts of gypsum preparation powder, 15-30 parts of dolomite powder, 20-40 parts of magnesite, 130-160 parts of fly ash; including 0.12-0.18% of iron ore tailings, 15-20% of fine sand, 39-45% of total mass of main materials 60°C water and 0.2±0.03% of admixtures; also include 6-10% of the total mass of the main material, anti-corrosion and rust inhibitor. The high-performance concrete solves the problems in the prior art that the high-performance concrete is eroded by sulfate, and the engineering quality is reduced, and even safety accidents are caused. |
