The invention discloses a method for preparing a new high-strength building material from tailings and waste residues, and belongs to the technical field of building material science and engineering. Wherein the special functional master batch comprises the following raw materials in parts by weight: 60-120 parts of modified tailing microspheres, 600-800 parts of aggregate, 40-80 parts of slag powder, 30-60 parts of fly ash, 5-15 parts of glass fibers, 2-8 parts of a crystallization regulating agent, 1-6 parts of an alkaline material, 2-4 parts of an active exciting agent, 1-3 parts of a water reducing agent, 12-25 parts of an adsorbent and 120-260 parts of water; the modified tailing microspheres are prepared from the following raw materials in parts by weight: 60 to 90 parts of modified tailing micro powder, 150 to 300 parts of eleostearic acid maleic anhydride modified benzoxazine resin, 100 to 200 parts of dimethylaminoethyl methacrylate, 3000 to 4000 parts of ethanol, 20 to 40 parts of slag powder and 0.1 to 2 parts of methyltriethoxysilane. The problems that in the prior art, tailings and waste residues are accumulated to occupy resources, concrete is lack of innovation, consequently, resources are wasted, and the requirement for high engineering materials cannot be met are solved. The method has the advantages of high performance and environmental protection.
