Manufacturing process of foamed cement aerated block for building
The invention discloses a manufacturing process of a foamed cement aerated block for buildings, which is characterized in that the foamed cement aerated block comprises the following materials: sand, silicon-containing tailings, a foaming agent (aluminum powder), a calcium material (lime and cement), fly ash and the balance of water. The fineness modulus of the sand ranges from 2.3 mm to 3.7 mm, and the silt content of the river channel sand or the mountain sand is controlled to be smaller than or equal to 5%; the silicon content of the silicon-containing tailings is 85% or above, the silt content is controlled to be smaller than or equal to 3%, and the particle size ranges from 0.001 mm to 1 mm; the materials are mixed and poured into a mold to form blocks. The method is simple to operate, convenient to construct, short in construction period and high in compressive strength, the building material with a good heat preservation effect can be prepared by adopting the method, mine waste and solid waste discharged by a coal-fired power plant are effectively utilized, energy conservation and environmental protection are achieved, the purpose of resource recycling is achieved, clay resources are saved, and environmental pollution and carbon emission caused by brick firing are reduced.
本发明公开了一种建筑用发泡水泥加气块的制做工艺，其特征在于：包括以下材料，砂，含硅尾矿，发气剂（铝粉），钙质材料（石灰、水泥），粉煤灰,其余为水；所述砂采用细度模数为2.3mm‑3.7mm之间，控制含泥量≤5%的河道砂或山砂的中粗砂；所述含硅尾矿采用含硅量85%或以上、控制含泥量≤3%、粒径为0.001mm‑1mm之间的含硅尾矿；以上材料混合浇筑模具成块。本发明操作简单，施工方便，施工周期短，抗压强度高，采用本发明可以制备出保温效果好的建筑材料，有效利用了矿山废料和燃煤电厂排出的固体废物，节能环保，达到了资源再生利用的目的，节约粘土资源，减少了砖烧制的环境污染和碳排放。
