Novel environment-friendly magnesite tailing brick and preparation method thereof
The invention provides a novel environment-friendly magnesite tailing brick and a preparation method thereof, and belongs to the technical field of building materials, the novel environment-friendly magnesite tailing brick comprises the following components by weight: 80-100 parts of magnesite tailings, 30-50 parts of ordinary Portland cement, 10-20 parts of silica fume, 5-15 parts of fly ash, 5-10 parts of reinforced fibers, 0.4-1 part of a water reducer, and 20-30 parts of water. By adding the modified silica fume, the rigid core-shell structure of the modified silica fume is favorable for improving the mechanical property of the brick, and the tailing brick obtained by the invention has better mechanical property and lower heat conductivity coefficient, and can be used in the field of wall bricks with higher mechanical strength and sound insulation performance.
本发明提供了一种新型环保菱镁尾矿砖及其制备方法，属于建筑材料技术领域，所述新型环保菱镁尾矿砖包括如下重量份组分：80‑100份菱镁尾矿、30‑50份普通硅酸盐水泥、10‑20份硅灰、5‑15份粉煤灰、5‑10份增强纤维、0.4‑1份减水剂、20‑30份水。通过添加改性硅灰，其刚性的核壳结构有利于提高砖块的力学性能，本发明得到的尾矿砖具有较好的力学性能及较低的导热系数，可以用于对力学强度和隔音性能较高的墙体砖领域。
