Composite cementitious material taking silicon-aluminum solid waste as raw material and preparation method of composite cementitious material
The invention relates to a composite cementing material taking silicon-aluminum solid waste as a raw material and a preparation method of the composite cementing material, and belongs to the technical field of solid waste recycling and composite cementing materials. The composite cementing material taking the silicon-aluminum solid waste as the raw material comprises the following raw materials in parts by weight: 55-35 parts of bauxite powder, 30-35 parts of slag, 15-30 parts of spontaneous combustion coal gangue powder and 3-6 parts of an activating agent, and the water-binder ratio is 0.3-0.34. According to the present invention, the low-activity bauxite powder can be utilized to prepare the high-performance composite cementing material, such that the raw material source of the cementing material preparation is expanded, the large amount of the industrial bulk solid waste can be consumed, and the environmental pollution is reduced. Meanwhile, a feasible basic scheme is provided for large-scale consumption of tailings rich in silicon and aluminum components.
一种以硅铝质固废为原料的复合胶凝材料及其制备方法，属于固废资源化及复合胶凝材料技术领域。所述硅铝质固废为原材料的复合胶凝材料，包含一下重量份的原料：铝土矿粉55～35份、矿渣30～35份、自燃煤矸石粉15～30份、活化剂3～6份，水胶比0.3～0.34。本发明能够利用低活性的铝土矿粉制备出具有高性能的复合胶凝材料，不仅拓展了胶凝材料的制备原料来源，而且能够大量消耗工业大宗固废，减少了环境污染。同时为大规模消纳富含硅铝组分尾矿提供具有可行性的基础方案。
