Method for preparing lightweight concrete aerated building block from lithium slag
The invention provides a method for preparing a lightweight concrete aerated building block from lithium slag. The method for preparing the lightweight concrete aerated building block from the lithiumslag comprises the following steps: (1) drying the lithium slag at normal temperature to obtain dried lithium slag; (2) grinding the dry lithium slag to obtain ground lithium slag; (3) mixing the ground lithium slag with aluminum powder paste and quick lime, and adding an additive to obtain a concrete admixture; (4) introducing low-pressure saturated steam into the concrete admixture, and heatingand stirring the mixture to obtain a stirred condensed soil admixture; and (5) putting the stirred condensed soil admixture into a mold for molding to obtain the molded condensed soil admixture. According to the invention, the building block mainly comprises the lithium slag, the quick lime, the foaming agent and other materials, so that the product has the advantages of low dry density, high compressive strength, low heat conductivity coefficient, convenience in transportation and the like, and can be widely applied to building materials.
本发明提供了一种锂渣制备轻质混凝土加气砌块的方法。所述锂渣制备轻质混凝土加气砌块的方法包括（1）将锂渣常温干燥，得到干燥锂渣；（2）将所述干燥锂渣进行研磨，得到研磨锂渣；（3）将所述研磨锂渣与铝粉膏及生石灰混合后，加入添加剂，得到混凝土掺合料；（4）将低压饱和蒸汽通入所述混凝土掺合料加热并对其进行搅拌，得到搅拌的冷凝土掺合料；（5）将所述搅拌的冷凝土掺合料放入模具中成型，得到成型的冷凝土掺合料。本发明的锂渣制备轻质混凝土加气砌块的方法的砌块主要由锂渣、生石灰、发泡剂等材料组成，具有干密度低、抗压强度高、导热系数低、便于运输等优点，可广泛用于建筑材料。
