Preparation method of graphite tailing-metakaolin-based geopolymer cementing material
The invention relates to the technical field of inorganic cementing materials, in particular to a preparation method of a graphite tailing-metakaolin-based geopolymer cementing material, which comprises the following steps: drying graphite tailings and metakaolin, and then screening; the preparation method comprises the following steps: mixing liquid sodium silicate, sodium hydroxide and water, uniformly stirring, and aging at room temperature to obtain an alkaline activator; pouring the graphite tailings and metakaolin into a stirrer, and stirring to obtain a mixture; pouring the obtained alkaline activator into the mixture of the stirrer, and stirring to obtain mixed slurry; the mixed slurry is poured into a mold, and then the mold is placed on a vibration table to be vibrated and exhausted; the treated mold is wrapped with a preservative film and then cured; after curing is completed, demolding is conducted to obtain a test block, the test block is cured in a curing chamber, and the graphite tailing-metakaolin-based geopolymer cementing material is prepared. The gelling material is prepared by matching the graphite tailings with the metakaolin, so that the environmental problem caused by massive accumulation of the graphite tailings is relieved.
本发明涉及无机胶凝材料技术领域，特别是涉及一种石墨尾矿‑偏高岭土基地质聚合物胶凝材料的制备方法，包括以下步骤，将石墨尾矿和偏高岭土烘干后筛分；将液体硅酸钠、氢氧化钠和水混合并搅拌均匀，在室温条件下陈化得到碱性激发剂；将石墨尾矿与偏高岭土倒入搅拌机中搅拌得到混合料；将得到的碱性激发剂倒入搅拌机的混合料中搅拌得到混合浆料；将的混合浆料倒入模具中，然后将模具放置于振动台上振动排气；将处理后的模具用保鲜膜包裹好后固化；固化完成后进行脱模得到试块，将试块在养护室内养护，制得石墨尾矿‑偏高岭土基地质聚合物胶凝材料。本发明使用石墨尾矿与偏高岭土相配合制备胶凝材料，缓解了石墨尾矿大量堆积带来的环境问题。
