Method for preparing aerated concrete block by using foundry sand
The invention provides a method for preparing an aerated concrete block by using foundry sand, and belongs to the field of building materials. The method comprises the following steps: a premix preparation step, a green body preparation step, a microwave treatment step and an autoclaved curing step. The aerated concrete block has the beneficial effects that the compressive strength of the prepared aerated concrete block can reach 5.6 to 5.7 MPa, the dry density can reach 584 to 592 kg/m < 3 >, the drying shrinkage value can reach 0.19 to 0.25 mm/m, the strength after freezing can reach 5.1 to 5.4 MPa, and the heat conductivity coefficient can reach 0.10 to 0.11 W/m.K.
本发明提供一种利用铸造型砂制备加气混凝土砌块的方法，属于建筑材料领域。所述方法由以下步骤组成：制备预混料步骤、制备坯体步骤、微波处理步骤、蒸压养护步骤。本发明的有益效果为：制得的加气混凝土砌块，抗压强度可达5.6‑5.7MPa，干密度可达584‑592kg/m3，干燥收缩值可达0.19‑0.25mm/m，冻后强度可达5.1‑5.4MPa，导热系数可达0.10‑0.11W/m·K。
