Coarse aggregate HUPC150 high-performance concrete and preparation method thereof

The invention discloses coarse aggregate HUPC150 high-performance concrete and a preparation method thereof, and belongs to the technical field of high-performance concrete materials. Comprising the following raw materials in parts by weight: 200 to 360 parts of cement, 210 to 380 parts of a fine agent material, 260 to 400 parts of coarse aggregate, 60 to 120 parts of water, 5 to 15 parts of an external additive, 50 to 80 parts of silica fume, 100 to 160 parts of microbeads, 70 to 100 parts of steel fibers, 10 to 12 parts of a water reducing agent, 10 to 20 parts of magnesium sulfate and 10 to 15 parts of modified calcium oxide. The high-performance concrete has the advantages that the compressive strength and breaking strength of the high-performance concrete can be improved, the mixing amount of the defoaming agent can be increased, the internal compactness of the material can be effectively increased, the mechanical property, durability and working performance of the concrete can be improved by adding mate
