Non-sintered basalt tailing brick and preparation method thereof
The invention provides a non-sintered basalt tailing brick and a preparation method thereof. The non-sintered basalt tailing brick is prepared from, by mass, 50-60 parts of basalt tailings, 40-50 parts of fly ash and 13-18 parts of alkaline excitant. According to the invention, the basalt tailings are excited by adopting the alkaline excitant, and the non-sintered tailing bricks with different strengths can be prepared through different proportions so that reasonable and large-scale utilization of tailing resources and solid waste resources is realized. The unconfined compressive strength of the basalt tailing brick prepared by the preparation method can reach 20.63 MPa at most; the basalt tailing brick prepared by the method meets the requirements of national standards of non-sintered garbage tailing bricks in the aspects of water absorption and the like, provides an appropriate thought for effective utilization of basalt tailings, brings reference for reasonable secondary utilizationof tailings and solid wastes, reduces energy loss and greenhouse effect, and can generate good social benefits, economic benefits and environmental benefits.
本发明提供一种非烧结玄武岩尾矿砖及其制备方法，该非烧结玄武岩尾矿砖按质量份计，由以下组分制得：玄武岩尾矿50‑60份、粉煤灰40‑50份、碱性激发剂13‑18份。本发明采用碱性激发剂对玄武岩尾矿进行激发，通过不同的配比可以制成不同强度的非烧结尾矿砖，实现了尾矿资源以及固体废弃物资源的合理大量利用。本发明制备成的玄武岩尾矿砖无侧限抗压强度最高可达20.63MPa，且在吸水率等等方面均满足《非烧结垃圾尾矿砖》国家标准的要求，为有效利用玄武岩尾矿提供一种合适的思路，为尾矿和固体废弃物的合理二次利用带来借鉴，减少了能源损耗和温室效应，能够产生很好的社会效益、经济效益和环境效益。
