Iron ore tailing porous energy-saving environment-friendly brick and preparation method thereof
The invention relates to the field of building materials, in particular to an iron ore tailing porous energy-saving environment-friendly brick which comprises the following components in parts by weight: 65-80 parts of iron ore tailings, 15-20 parts of a cementing material, 25-30 parts of lead powder, 18-22 parts of aggregate, 5-8 parts of an adhesive and 8-12 parts of water. The iron ore tailingsare waste obtained after iron ore separation, the lead powder is particles with the particle size being 0.2-0.5 mm, the adhesive is epoxy resin, the aggregate is natural sand with the particle diameter being 0.2-2 mm, and the cementing material is Portland cement with the mark number being 425 #. The iron ore tailings are effectively used as a main raw material for manufacturing the porous brick,so that mineral resources can be fully utilized, the utilization range of the mineral resources is expanded, and effective unification of resource benefits, economic benefits and environmental benefits is achieved. The lead powder is added into the raw materials, so that the radiation in the iron ore tailings can be effectively reduced by utilizing the lead element characteristics.
本发明涉及建筑材料领域，特别是指铁矿尾矿多孔节能环保砖，其包括有如下重量份的组分：铁矿尾矿65～80份，胶凝材料15～20份，铅粉25～30份，骨料18～22份，粘合剂5～8份；水8～12份。其中，所述铁矿尾矿为铁矿矿选后的废弃物，所述铅粉粒径为0.2～0.5mm的颗粒，所述粘合剂为环氧树脂，所述骨料为颗粒直径在0.2～2mm之间的天然砂，所述胶凝材料为标号425#的硅酸盐水泥。本发明有效的利用铁矿尾矿作为主要原料制作多孔砖，可以充分利用矿产资源，扩大矿产资源利用范围，实现资源效益、经济效益和环境效益的有效统一。并且在原料中通过添加的铅粉，利用铅元素特性可有效的降低铁矿尾矿中辐射。
