Preparation method of aerated concrete block
The invention discloses a preparation method of an aerated concrete block, which belongs to the technical field of preparation of building materials. According to the invention, calcium carbide subjected to semi-dry oil surface modification is used as an air entraining agent; and a plurality of effective components are used as air inlet components. The porous rock wool fibers are coupled with themodified calcium carbide powder; the fiber strength is improved, the red mud contains aluminum oxide, calcium oxide and other metal oxides; the aluminum oxide exists in the red mud in the form of crystalline fibers; after pressing and sintering, the crystalline fibers are longitudinally oriented in the aerated concrete block and are crossed and wound with the porous rock cotton fibers in the aerated concrete block to form a woven mesh, so that the mechanical strength of the aerated concrete block is further enhanced, the heat preservation and insulation performance of the aerated concrete block is improved, and the application prospect is wide.
本发明公开了一种加气混凝土砌块的制备方法，属于建筑材料制备技术领域。本发明以经过半干性油表面改性的电石作为加气剂，多种有效组分作为进气组分本发明中多孔岩棉纤维与改性电石粉偶联后，使纤维强度提高，本发明中赤泥中含有氧化铝、氧化钙等金属氧化物，氧化铝在赤泥中以结晶纤维存在，经压制烧结后，结晶纤维在加气混凝土砌块中纵向取向，与加气混凝土砌块中多孔岩棉纤维交叉缠绕，形成编织网，不仅进一步增强加气混凝土砌块力学强度，提高加气混凝土砌块保温隔热性能，应用前景广阔。
