Micro-nano solid waste based composite cementing material and preparation method thereof
The invention discloses a micro-nano solid waste-based composite cementing material and a preparation method thereof. The cementing material is prepared from the following raw materials in percentage by weight: 25-45% of an aluminum oxide hot material, 18-25% of a tailing sand material A, 15-22% of a tailing sand material B, 10-16% of a blast furnace mineral powder material, 8-12% of calcium silicate, 5-12% of a catalyst and 10-15% of an anti-freezing agent. The sum of all the components is 100%. The preparation method of the cementing material comprises the following steps: 1) screening, dehydrating and drying the aluminum oxide hot material, the tailing sand A material and the tailing sand B material, grinding the materials to 1200-1800 meshes by using an airflow mill, screening, respectively selecting fine materials with the particle size of DN50 +/-5, and putting the fine materials into a No.1 premixing bin to obtain a mixture A; (2) selecting blast furnace mineral powder, calcium silicate, a catalyst and an antifreeze agent according to the weight percentage, and putting the materials into a second premixing bin to obtain a mixture B; and (3) putting the mixture A and the mixture B into a total stirrer, fully stirring until the mixture is uniformly mixed to obtain a synthetic mixture, and packaging and warehousing after the synthetic mixture is detected to be qualified to obtain a finished product.
本发明公开了一种微纳米固废基复合胶凝材料及其制备方法，所述胶凝材料由以下重量百分比的原料组成：25‑45％的铝氧热料、18‑25％的尾矿砂A料、15‑22％尾矿砂B料、10‑16％的高炉矿粉料、8‑12％的硅酸钙、5‑12％的催化剂、10‑15％的抗冻剂；所有组分之和为100％；所述胶凝材料制备方法，包括以下步骤：1)将铝氧热料、尾矿砂A料、尾矿砂B料经分筛处理、脱水、烘干处理，利用气流磨磨细至1200‑1800目，筛分，分别选取粒径度为DN50±5细料，投入一号预混仓，得混合物A；2)按重量百分比选取高炉矿粉料、硅酸钙、催化剂、抗冻剂，投入到二号预混仓，得混合物B；3)将混合物A与混合物B投入至总搅拌器，充分搅拌至混合均匀，得合成混料，经检测合格后，包装入库，可得成品。
