Sintered water permeable brick prepared from iron tailings and preparation method of sintered water permeable brick
The invention discloses a sintered water permeable brick prepared from iron tailings and a preparation method of the sintered water permeable brick, and relates to the field of green building materials. A sintered water permeable brick material comprises the raw materials in parts by weight: 60-75 parts of fine iron tailings with a particle size range of 150-400 mesh, 5-20 parts of a pore-forming agent with a particle size range of 20-40 mesh, 1-5 parts of a fluxing agent with a particle size range of 15-30 mesh, and 10-15 parts of a binder. Expanded perlite, bamboo charcoal powder, starch and the like are used as the pore-forming agent, so that communicated pores are formed in the water permeable brick in the sintering process. Easily-decomposed inorganic salt and low-melting-point mineral powder are used as the fluxing agent, so that the sintering temperature of the water permeable brick is reduced, and the mechanical property of the sintered water permeable brick is improved. The raw materials for preparing the sintered water permeable brick product are easy to obtain, the preparation cost is low, the method for preparing the high-performance sintered water permeable brick from the fine iron tailings is provided, and the problem of resource comprehensive utilization of the fine iron tailings can be solved.
本发明公开一种铁尾矿制备的烧结透水砖及其制备方法。涉及绿色建筑材料领域，该烧结透水砖材料，其原料组成按重量份计：60‑75份粒径范围为150‑400目细铁尾矿，5‑20份粒度范围为20‑40目的造孔剂，1‑5份粒度范围为15‑30目的助熔剂,10‑15份粘结剂。本发明以膨胀珍珠岩、竹炭粉和淀粉等作为造孔剂，使透水砖内部在烧结过程中形成连通气孔。采用易分解无机盐和低熔点矿物粉体为助熔剂，降低透水砖烧结温度，提高烧结透水砖力学性能。本发明制备烧结透水砖制品原料易得、制备成本低，提供了细铁尾矿制备高性能烧结透水砖的方法，可解决细铁尾矿资源化综合利用问题。
