Iron tailing sludge baking-free brick and preparation method thereof
The invention discloses an iron tailing sludge baking-free brick and a preparation method thereof, and belongs to the technical field of building materials. The brick is prepared from the following main raw materials in parts by mass: 45-65 parts of iron tailing sludge, 15-22 parts of cement, 4-9 parts of aggregate iron ore waste stone nitrate, 5-8 parts of sand, 3-5 parts of a coagulator, 1-3 parts of an adhesive, 5-8 parts of coal gangue and 10-15 parts of water. Compared with a traditional baking-free brick, the cement consumption can be reduced, the compression resistance and the water permeability of the baking-free brick meet the national standard baking-free brick standard, and the preparation method is convenient to implement. The baking-free brick provided by the invention has a remarkable rapid hardening effect, the strength of the baking-free brick can reach 60%-70% of the required strength within 2-3 days at the initial stage of processing completion, the production period is greatly shortened, the iron tailing sludge waste can be reasonably recycled, the waste is turned into wealth on the basis of saving resources, and the environment is protected.
本发明公开了一种铁尾矿污泥免烧砖极其制备方法，属建材技术领域。由下述质量份的主要原料制成:铁尾矿污泥45—65份、水泥15—22份、骨料铁矿废石硝4‑9份、砂子5‑8份、凝固剂3‑5份、粘合剂1‑3份、煤矸石5‑8份，水10‑15份。本发明相较于传统的免烧砖能够节约水泥的用量，其抗压性能和透水性能均符合国标免烧砖标准，且本发明的制备方法方便实施。本发明的免烧砖速凝效果显著，在加工完成初期的2‑3天即可使免烧砖的强度达到要求强度的60％‑70％，大大缩短了生产周期，本发明能合理的再利用铁尾矿污泥废料，在节约资源的基础上，变废为宝，保护了环境。
