Regenerated micro-powder foam concrete and preparation method thereof
The invention belongs to the technical field of building material manufacturing, and particularly discloses regenerated micro-powder foam concrete and a preparation method thereof. The preparation method comprises the following steps: performing dry powder mixing on waste concrete micro powder, cement, fly ash, a foam stabilizer, a water reducing agent and an instant setting agent according to a specific ratio, and then adding water for mixing to obtain foam concrete slurry; and mixing with a foamed foaming agent and mineral fibers, and curing to obtain the regenerated micro-powder foam concrete. The regenerated micro-powder foam concrete prepared by the invention is used for protecting the frozen soil roadbed, so that the temperature field of the frozen soil roadbed is stable, heat transfer is effectively blocked, and the regenerated micro-powder foam concrete has a good heat preservation and insulation effect; compared with EPS (Expandable Polystyrene) and XPS (Expandable Polystyrene) plates, the regenerated micro-powder foam concrete has the advantages of low manufacturing cost, abundant raw materials, convenience in transportation and easiness in processing, and the use of the waste concrete micro-powder is beneficial to recycling of construction wastes, so that the pollution of the construction wastes to the environment is reduced.
本发明属于建筑材料制造技术领域，具体公开了一种再生微粉泡沫混凝土及其制备方法。本发明将特定配比的废弃混凝土微粉、水泥、粉煤灰、稳泡剂、减水剂、瞬凝剂进行干粉混合，然后添加水进行混合，得到泡沫混凝土料浆；然后与经过发泡的发泡剂、矿物纤维混合，养护，得到再生微粉泡沫混凝土。将本发明制备的再生微粉泡沫混凝土用于冻土路基的保护，能够使冻土路基温度场的稳定，有效阻隔热量传递，有着良好的保温隔热效果；再生微粉泡沫混凝土比EPS、XPS板材造价低、原材丰富、运输方便、易加工，废弃混凝土微粉的使用有利于建筑垃圾循环再利用，减少建筑垃圾对环的污染。
