Ultrahigh-strength concrete prepared from superfine copper tailings

The invention discloses ultrahigh-strength concrete prepared from superfine copper tailings and a preparation method of the ultrahigh-strength concrete. The ultrahigh-strength concrete is prepared from the following raw materials: the superfine copper tailings, cement, silica fume and fly ash. The ultra-fine copper tailings are used for replacing part of cement to serve as the admixture to prepare the ultra-high-strength concrete, the pore structure of the prepared concrete is refined, and the mechanical property is enhanced. The superfine copper tailings have the following advantages that on one hand, the superfine copper tailings are small in particle size and have an excellent filling effect, and on the other hand, the superfine copper tailings are mineral substances containing silicate and aluminate and are rich in heavy metal ions, and the ions can effectively promote formation of hydration products in the ion chelation process. In the process of preparing the concrete from the superfine copper tailings,
