The invention discloses an anti-corrosion concrete and application of the same to road construction or bridge construction in salt marsh areas. The anti-corrosion concrete is prepared by adding fly ash, silica fume and an expanding agent into common concrete, wheren the doping amounts of the fly ash, the silica fume and the expanding agent account for 21%, 5% and 1.2% of the total amount of a cementing material, respectively; and the total amount of the cementing material refers to the total mass of cement and fly ash. According to the invention, in virtue of a control variate method, the obtained expanding agent has favorable effect on the compactness of the concrete under the condition of different additives, and since ettringite produced by addition of the expanding agent is fused withthe concrete after expansion, holes in the concrete are filled up and the concrete is compacted; and through ratio debugging, the concrete of the invention has obvious corrosion resistant and can effectively alleviate damage of high-concentration salt marsh areas to pile foundation concrete in special environments.
