The invention belongs to a method for utilizing resources. The method utilizes the matter characteristics of solid wastes (six kinds of waste residues) such as red mud(the sintered method and the Bayer method), boiler slag, ore dressing tailings, ash and gas generation slag, which are generated during the manufacturing process in aluminum industry, and converts the solid wastes into a novel road material and construction walling material by the processes such as drying, crushing, reasonable proportioning, machine shaping(grinding and extrusion) and consolidation or sintering. The method is characterized in that the utilization ratio of the waste residues is 100 percent. The waste residues comprise the following compositions: (1) the produced road material-curing agent, which can be used to reinforce a highway subgrade and bases of road surface substrates(substrate and subbase) and buildings and completely replace cement, lime and sandstone materials, and the road material can meet prior national(industrial) standards and environmental protection standards in performance; and (2) the produced construction walling materials-non supporting brick, supporting brick, air brick, hollow building block, common tile, glazed roof tile and andorful tile, which are superior to the prior national standards in performance. The material obtained by the invention has the characteristics of energy conservation, thermal insulation, high strength, corrosion resistance, efflorescence resistance and no pollution.
