Preparation method of high-strength foamed concrete
The invention belongs to the technical field of concrete, and particularly relates to a preparation method of high-strength foamed concrete. The preparation method of the high-strength foamed concrete provided by the invention comprises the following steps: mixing steel slag, fly ash, carbide slag, desulfurized gypsum, water and aluminum powder to obtain foamed slurry; pressurizing and foaming the foamed slurry to obtain primary foamed concrete; sequentially subjecting the primary foamed concrete to autoclaved curing and carbonization curing so as to prepare the high-strength foamed concrete. According to the invention, industrial solid wastes are used as raw materials, and the foamed concrete with relatively high strength is prepared under the process condition of combining pressurized foaming, autoclaved curing and carbonization curing; the slurry can be uniformly and stably foamed through pressurized foaming, so that independent spherical closed holes can be formed and can be uniformly distributed; and calcium carbonate particles generated in carbonization curing are filled in pores of the concrete, so that the compressive strength of the high-strength foamed concrete is improved.
本发明属于混凝土技术领域，具体涉及一种高强度发泡混凝土的制备方法。本发明提供的高强度发泡混凝土的制备方法，包括以下步骤：将钢渣、粉煤灰、电石渣、脱硫石膏、水和铝粉混合，得到发泡浆料；将所述发泡浆料进行加压发泡，得到初级发泡混凝土；将所述初级发泡混凝土依次进行蒸压养护和碳化养护，得到所述高强度发泡混凝土。本发明以工业固体废弃物为原料，在加压发泡、蒸压养护和碳化养护相结合的工艺条件下制备得到具有较高强度的发泡混凝土。所述加压发泡能够使浆料均匀稳定的发泡，利于形成独立球型封闭孔，使得泡孔均匀分布；碳化养护中生成的碳酸钙颗粒填充在混凝土的孔道中，提高了高强度发泡混凝土的抗压强度。
