The invention discloses a preparation method of waterproof foamed concrete, and belongs to the technical field of concrete. The preparation method comprises the following steps: mixing cement, fly ash, active silicon powder, glass fibers, fine gravel powder and water, and putting the mixture into a stirrer for fully stirring; transferring the mixed material into a mixer for working for the first time, adding a water reducing agent, a reinforcing agent, an early strength agent, a toughening agent, a foam stabilizer, a rheological additive and a thickening agent into the mixed material, and stirring again; adding a foaming agent into the materials, and starting the mixer for stirring again; the mixed materials are poured into corresponding molds for forming work, demolding work is conducted after concrete forming, and the demolded foamed concrete is cut, the foamed concrete is low in water absorption rate, waterproof, free of powder falling and high in strength, and compared with traditional foamed concrete, the production cost is low, the generated energy consumption is low, and the production cost is low. And a traditional high-temperature autoclaving process is not needed, the use scene is large, and the applicability is high.
本发明公开了一种不透水的发泡混凝土的制备方法，属于混凝土技术领域将水泥、粉煤灰、活性硅粉、玻璃纤维、细砂石粉和水混合，放入搅拌机内部充分搅拌；将混合后的物料转移至混料机内部首次进行工作，并向混合完成后的物料中加入减水剂、增强剂、早强剂、增韧剂、稳泡剂、流变助剂和增稠剂再次搅拌；将发泡剂加入物料中，启动混料机再次进行搅拌工作；将混合处理完成的物料倒入对应模具中进行成型工作，在混凝土成型后进行脱模工作，并对脱模后的发泡混凝土进行切割，本发明中的发泡混凝土吸水率低，不透水，不脱粉、强度高，相对传统发泡混凝土生产成本低，产生能耗低，且不需传统的高温压蒸的工艺，使用场景大，适用性强。
