The invention discloses marine concrete with high corrosion resistance and a preparation method thereof, and belongs to the technical field of marine concrete. The maritime work concrete is prepared from the following raw materials in parts by weight: 300 to 400 parts of cement, 500 to 600 parts of fine aggregate, 400 to 500 parts of coarse aggregate, 50 to 100 parts of fly ash, 100 to 150 parts of water, 10 to 20 parts of filler, 20 to 30 parts of mixed modified fiber, 1 to 3 parts of water reducing agent, 1 to 3 parts of urea and 1 to 3 parts of calcium sulphoaluminate. The gradient low-concentration silica sol is used for preparing the modified fibers, the modified fibers are compounded and then added into the marine concrete, the erosion resistance and the strength performance of the concrete are greatly improved, the preparation process is simple, and the obtained concrete is good in comprehensive performance and suitable for being used in the complex marine environment. 本发明公开高耐侵蚀的海工混凝土及其制备方法，属于海工混凝土技术领域
