Aerated concrete block and production process thereof
The invention relates to the technical field of autoclaved aerated concrete, in particular to an aerated concrete block and a production process thereof, and the production process comprises the following steps: (1) slurry preparation: mixing ceramic polishing powder, tailings, sand, fly ash, high-silicon mud and gypsum, performing wet ball milling to required particle size, and adding water to prepare slurry; (2) ingredient stirring: adding quick lime and cement into the slurry, stirring and mixing, then adding aluminum powder, and continuously stirring uniformly to obtain a concrete material; (3) pouring; (4) standing and maintaining; (5) demolding and cutting; and (6) steam curing. The production process disclosed by the invention is simple in steps, short in flow, short in production period, high in production efficiency and suitable for continuous large-scale production. The aerated concrete block prepared by the invention is excellent in comprehensive performance, light in weight, excellent in compressive strength and drying shrinkage performance, good in impermeability, freezing resistance, crack resistance, fire resistance, sound insulation and thermal insulation performance, and more economical and environment-friendly in use.
本发明涉及蒸压加气混凝土技术领域，具体涉及一种加气混凝土砌块及其生产工艺，包括如下步骤：(1)料浆制备：将陶瓷抛光粉、尾矿、砂、粉煤灰、高硅泥和石膏混合后采用湿法球磨成所需的粒径，加水配成料浆；(2)配料搅拌：在料浆中加入生石灰和水泥，搅拌混合后再加入铝粉，继续搅拌均匀，得到混凝土料；(3)浇注；(4)静停养护；(5)脱模切割；(6)蒸汽养护。本发明的生产工艺步骤简单，流程短，生产周期短，生产效率高，适合连续规模化生产。本发明制得的加气混凝土砌块综合性能优异，质量轻，抗压强度和干燥收缩性能优异，抗渗性能、抗冻性、抗裂性、防火性、隔音性和保温性能好，使用更加经济环保。
