Sand aerated concrete block prepared from foundry waste sand and preparation method and preparation device
The invention relates to the technical field of aerated concrete blocks, in particular to a sand aerated concrete block prepared from foundry waste sand, a preparation method and a preparation device. The casting waste sand is prepared from the following raw materials in parts by mass: 75-90 parts of casting waste sand, 20-40 parts of quick lime, 55-70 parts of cement, 15-20 parts of gypsum, 0.3-0.5 part of aluminum paste and 1.5-2 parts of sodium carbonate. and 75-90 parts of clear water. The sand aerated concrete block is prepared from the foundry waste sand, so that the foundry waste sand is turned into wealth, resource regeneration is achieved, the resource utilization rate is increased, and the production cost of the sand aerated concrete block is reduced. The preparation method is reasonable, low in production energy consumption and high in product precision. When the device is used for demolding the mold, the demolding process is simple and rapid, operation is convenient, and the machining efficiency of the sand aerated concrete blocks is improved.
本发明涉及加气混凝土砌块技术领域，具体的说是一种利用铸造废砂制备的砂加气混凝土砌块及制备方法和装置，该利用铸造废砂制备的砂加气混凝土砌块，包括以下质量组分的原料：铸造废砂75‑90份、生石灰20‑40份、水泥55‑70份、石膏15‑20份、铝膏0.3‑0.5份、纯碱：1.5‑2份；和清水75‑90份。本发明的砂加气混凝土砌块利用铸造废砂进行制备，使得铸造废砂变废为宝，实现资源再生，提高资源利用率，降低砂加气混凝土砌块的生产成本。本发明的制备方法合理，生产能耗低，产品精度高。本发明的装置对模具进行脱模时，脱模过程简单快捷，便于进行操作，提高砂加气混凝土砌块的加工效率。
