Solid waste-based sintered brick and preparation method thereof
The invention relates to the technical field of solid waste recovery, in particular to a solid waste-based sintered brick and a preparation method thereof. The solid waste-based sintered brick is prepared from the following raw materials: 100 parts of solid waste, 0.5-1 part of a sintering aid, 5-10 parts of nano silica fume, 10-20 parts of liquid water glass and 10-20 parts of water, the solid wastes comprise 0-50 parts of red mud and 50-100 parts of mineral powder; the preparation method comprises the following steps: uniformly mixing the solid waste with the sintering aid to obtain a premixed dry material; mixing nanometer silica fume, liquid water glass and water to obtain an alkali-activated reinforcing agent; adding an alkali-activated reinforcing agent into the premixed dry material, and stirring and mixing to obtain a cementing material; carrying out vibration molding on the cementing material to obtain a brick green body; drying the brick green body to obtain a dried green body; and roasting the dried green body to obtain the solid waste-based sintered brick. The solid waste-based sintered brick prepared by the invention has the advantages of high strength, strong durability, no obvious saltpetering phenomenon, and realization of resource utilization of solid wastes.
本发明涉及固体废物回收技术领域，具体涉及一种固废基烧结砖及其制备方法。固废基烧结砖的原料包括固体废弃物100份，烧结助剂0.5‑1份，纳米微硅粉5‑10份，液体水玻璃10‑20份，水10‑20份；固体废弃物包括赤泥0‑50份，矿粉50‑100份；制备步骤包括将固体废弃物与烧结助剂混匀得到预混干料；将纳米微硅粉、液体水玻璃与水混合得到碱激发增强剂；将碱激发增强剂加入至预混干料中搅拌混合得到胶凝材料；将胶凝材料振动成型，得到砖生坯；将砖生坯烘干，得到干燥坯体；将干燥坯体进行焙烧，得到固废基烧结砖。本发明制得的固废基烧结砖强度高、耐久性强，不产生明显泛碱现象，可实现固体废弃物的资源化利用。
