Non-sintered roofing slate tailing brick and preparation method thereof
The invention relates to the technical field of building materials, and discloses a non-sintered roofing slate tailing brick and a preparation method thereof. The tailing brick comprises the followingraw material components in parts by mass: 50-60 parts of roofing slate tailings, 30-50 parts of fly ash, 5-10 parts of metakaolin and 12-16 parts of an alkaline activator. The preparation method of the tailing brick comprises the following steps: carrying out dry mixing on roofing slate tailings, fly ash and metakaolin, adding the alkaline activator and water, carrying out uniform stirring and mixing to obtain a mixture, carrying out compression molding on the mixture, and carrying out natural curing to obtain the tailing brick. According to the invention, the roofing slate tailings are usedas a matrix, and a large amount of industrial waste residues, namely fly ash is digested at the same time, so the prepared tailing brick has a stable immobilization effect, a new way is provided for reasonable secondary utilization of tailings and solid waste, energy loss is reduced, and environmental pollution caused by brick sintering is also effectively reduced.
本发明涉及建筑材料技术领域，公开了一种非烧结瓦板岩尾矿砖及其制备方法。该尾矿砖包括以下原料组分，以质量份计为：瓦板岩尾矿50‑60份、粉煤灰30‑50份、偏高岭土5‑10份、碱性激发剂12‑16份。该尾矿砖的制备方法包括以下步骤：将瓦板岩尾矿、粉煤灰和偏高岭土进行干混，然后加入碱性激发剂和水搅拌混匀，得到混合料，将所述混合料压制成型后，自然养护，得到所述尾矿砖。本发明中尾矿砖以瓦板岩尾矿作为基体，同时大量消化工业废渣粉煤灰，制得的尾矿砖具有稳定的固化效果，为尾矿和固体废弃物的合理二次利用提供新的途径，减少了能源损耗，也有效减少烧结砖形成的环境污染。
