The present invention relates to the technical field of building materials, and in particular relates to mineral waste admixture hydraulic concrete, which is prepared by mixing and stirring medium sand, gravel, II fly ash, cement, mineral powder, an anti-permeability anti-alkali-reaction active agent and water, the mineral waste admixture hydraulic concrete per cubic meter comprises, by volume, 35%-37% of the medium sand, 22.5%-23% of the gravel, 7%-9% of the II fly ash, 17%-19% of the cement, 13%-13.5% of the mineral powder, 0%-0.2% of the anti-permeability anti-alkali-reaction active agent and 1%-3% of the water; the mineral waste admixture hydraulic concrete is prepared by stirring in the ratio and molding by high frequency vibrating and vertical extrusion, first, by addition of the fly ash and mineral powder in the formulation, waste slag needed to be processed by manufacturing companies is solved, waste is recycled, more importantly, compactness and overall strength of building blocks are improved, the overall strength exceeds the national standard by 10Mpa; secondly, by addition of the anti-permeability anti-alkali-reaction active agent, the case of inspection well water leakage is solved, sewage infiltration is prevented, and groundwater resources are effectively protected.
