Cement clinker and preparation method thereof
The invention provides a cement clinker and a preparation method thereof. The cement clinker comprises the following components in parts by weight: 40-70 parts of phosphate tailings, 5-20 parts of steel slag, 5-20 parts of copper tailings, 5-10 parts of coal gangue and 10-30 parts of nickel-containing industrial solid waste. The high-magnesium high-iron-phase cement clinker is produced by completely utilizing industrial solid wastes, so the production cost is reduced, the industrial solid wastes are consumed, and sustainable development of the cement industry is promoted. The method has remarkable economic and social benefits. And the sintered high-magnesium high-iron-phase cement clinker is qualified in later-stage stability, and has excellent performances such as micro-expansion, wear resistance and scouring resistance.
本发明提供一种水泥熟料及其制备方法。所述水泥熟料包括以下组分：磷尾矿40‑70重量份，钢渣5‑20重量份，铜尾矿5‑20重量份，煤矸石5‑10重量份，含镍工业固废10‑30重量份。本发明全部利用工业固体废弃物生产高镁高铁相水泥熟料，生产成本降低且消纳工业固废，促进水泥工业可持续发。本发明具有显著的经济和社会效益。且烧成的高镁高铁相水泥熟料，后期安定性合格，且具有微膨胀、耐磨损和冲刷等优越性能。
