The invention relates to the technical field of aerated brick preparation, and discloses a mineral powder aerated brick and a preparation method thereof. The raw materials of the mineral powder aerated block brick comprise dry materials and water, wherein the raw materials of the mineral powder aerated block brick comprise a first dry material, a second dry material and water, the first dry material comprises fly ash, desulfurized gypsum, carbide slag and mirabilite, the second dry material comprises quick lime, aluminum powder and blast furnace mineral powder, the weight ratio of the water to the first dry material is 2.1-5.5:2, the weight ratio of the fly ash to the desulfurized gypsum to the carbide slag to the mirabilite to the quick lime to the aluminum powder to the blast furnace mineral powder is (386-396):(120-130):(8-12):(15-21):(200-280):(1-2):130. The aerated brick has no defects on the surface, and the out-of-kettle strength is greater than or equal to 3.7 MPa and meets the national standard; the maintenance strength in 7 days is greater than or equal to 4.5 MPa; the curing strength in 10 days is greater than or equal to 5.0 MPa and can reach a 5.0 MPa superior product grade; and in addition, cost is saved, and large economic benefits are created.
本发明涉及加气块砖制备技术领域，公开了一种矿粉加气块砖及其制备方法。所述矿粉加气块砖的原料包括干料和水，其中，所述矿粉加气块砖的原料包括第一干料、第二干料和水，其中，所述第一干料包括粉煤灰、脱硫石膏、电石渣和芒硝，所述第二干料包括生石灰、铝粉和高炉矿粉，所述水与所述第一干料的重量比为2.1‑5.5:2，所述粉煤灰、所述脱硫石膏、所述电石渣、所述芒硝、所述生石灰、所述铝粉和所述高炉矿粉的重量比为386‑396:120‑130:8‑12:15‑21:200‑280:1‑2:130。该加气块砖表面无缺陷，且出釜强度≥3.7MPa，符合国家标准；7天养护强度≥4.5MPa；10天养护强度≥5.0MPa，可达5.0MPa优等品级别；而且，节约成本，创造了较大的经济效益。
