The invention provides a concrete material for reinforcing a high-performance structure project, a preparation method and a use thereof, wherein, the components and the using amounts of the concrete material are as follows: cement, 400-900Kg/M<3>; coarse aggregate, 300-950Kg/M<3>; fine aggregate, 500-1050Kg/M<3>; shrinkage-compensating admixture, 0-100Kg/M<3>; polymeric additive, 1-15Kg/M<3>; silica fume, 0-65Kg/M<3>; and fiber, 0.5-2.5Kg/M<3>; the particle size of the coarse aggregate is 5-16mm, the particle size of the fine aggregate is less than 5mm, the water content of various raw materials is not less than 1.5 percent, and the adding amount of water is 7-11 percent of the dry materials during the use process. The preparation method of the concrete material comprises the following steps: the raw materials are selected and taken according to the components and the using amounts, stirred by a machine for more than 3 minutes, then packaged with water-and moisture-proof materials. The concrete material is applicable to the cross-section enlargement of a concrete member in the structure project, the replacement and the repair of the failure concrete, the increase of the concrete member, etc.
