Metal tailing cementing material and preparation method and application thereof
The invention discloses a metal tailing cementing material which is prepared from the following raw materials in parts by weight: 70-100 parts of metal tailings, 0.1-30 parts of cementing material. The preparation method comprises the following steps: (1) weighing the raw materials; and (2) mixing and grinding the metal tailings and a cementing material, and sieving to obtain the metal tailings. The content of clinker used by the cementing material does not exceed 50%, a large amount of metal tailings stacked into a mountain can be consumed, and the effect of turning waste into wealth is achieved; the preparation method disclosed by the invention is a low-cost grinding process and can be directly used without calcining, so that the production cost is reduced; and the special cementing material for foam concrete prepared by the technical scheme of the invention has low hydration heat, can be used for continuous construction, and avoids the problem of low efficiency of layered construction in traditional construction.
本发明公开了一种金属尾矿胶凝材料，包括以下重量份的原料：一种金属尾矿胶凝材料，包括以下重量份的原料：金属尾矿70‑100份、胶凝材料0.1‑30份；制备方法：(1)称取各原料；(2)将金属尾矿与胶凝材料混合研磨，过筛，即得。本发明胶凝材料所使用的熟料含量不超过50％，同时可消耗大量堆积成山的金属尾矿，起到了“变废为宝”的作用；本发明制备方法为低成本的研磨工艺，无需煅烧即可直接使用，降低了生产成本；由本发明技术方案制得的泡沫混凝土专用胶凝材料水化热低，可连续施工，避免了传统施工中需要分层施工的低效问题。
