Method for producing high-performance autoclaved aerated concrete block from granite powder
The invention discloses a method for producing a high-performance autoclaved aerated concrete block from granite stone powder, which comprises the following steps: 1, uniformly stirring granite stone powder and tailing sand, and carrying out ball milling to prepare mortar with the specific gravity of 1.6 kg/L and the fineness of below 15%; 2, respectively adding lime, cement, aluminum powder, a fiber additive and water into the prepared mortar, and stirring for 150s; 3, pouring the uniformly stirred mixture, and controlling the temperature to be 45-50 DEG C; 4, the obtained molded product is subjected to constant-temperature curing at 60 DEG C for 3 hours; 5, demolding the blank which meets the hardness requirement after standing; sixthly, a finished product obtained after demolding is cut according to set requirements; and 7, the cut finished product is subjected to steam curing, it is guaranteed that steam curing is conducted for 12 hours, the pressure is smaller than or equal to 12.5 Mpa, and the temperature is smaller than or equal to 193 DEG C. Performance indexes such as strength and appearance quality of the product can be improved, and the product meeting technical index requirements can be manufactured.
本发明公开了一种花岗岩石粉生产高性能蒸压砂加气混凝土砌块的方法，包括如下步骤：步骤一：将花岗岩石粉和尾矿砂搅拌均匀后进行球磨，制备成比重为1.6kg/L，细度为15％以下的砂浆；步骤二：将石灰、水泥、铝粉、纤维外加剂和水分别加入到上述制备好的砂浆中进行搅拌150s；步骤三：将上述搅拌均匀的混合物进行浇注，温度控制在45‑50℃；步骤四：将上述得到的成型产品进行3小时的60度的恒温养护；步骤五：静养达到硬度要求的坯体进行脱模；步骤六：将脱模后的成品根据设置要求进行切割；步骤七：将切割后的成品进行蒸养，且保证12小时的蒸养，压力≤12.5Mpa，温度≤193度。本发明可以提高产品的强度，外观质量等性能指标，制作出符合技术指标要求的产品。
