Autoclaved aerated concrete prepared from furnace bottom slag and preparation method of autoclaved aerated concrete
The invention relates to the field of concrete, and particularly discloses autoclaved aerated concrete prepared from furnace bottom slag and a preparation method of the autoclaved aerated concrete. The autoclaved aerated concrete prepared from the furnace bottom slag comprises granulated blast furnace slag, carbon slag, quartz sand, Portland cement, lime, desulfurized gypsum, aluminum powder, reinforced fibers and a foam stabilizer. The preparation method comprises the following steps: mixing granulated blast-furnace slag, carbon slag, quartz sand and water to prepare slurry, stirring, adding lime and desulfurized gypsum, adding reinforced fibers into the slurry, uniformly stirring, adding Portland cement, adding a foam stabilizer, standing for thickening, adding aluminum powder, stirring, pouring into a mold, and carrying out heat preservation for 2-3 hours, thereby obtaining the high-strength concrete. Curing the concrete in the mold, demolding, cutting a green body, and performing high-temperature and high-pressure steam curing on the green body to obtain the autoclaved aerated concrete. The autoclaved aerated concrete prepared from the furnace bottom slag has the advantage that the problem of high water absorption of the autoclaved aerated concrete is solved.
本申请涉及混凝土领域，具体公开了一种利用炉底渣制备的蒸压加气混凝土及其制备方法。利用炉底渣制备的蒸压加气混凝土包括粒化高炉矿渣、碳渣、石英砂、硅酸盐水泥、石灰、脱硫石膏、铝粉、增强纤维、稳泡剂；其制备方法为：将粒化高炉矿渣、碳渣、石英砂和水混合制成浆液，搅拌并加入石灰和脱硫石膏，将增强纤维加入到浆液中，搅拌均匀后加入硅酸盐水泥，再加入稳泡剂，静置稠化后加入铝粉，搅拌后浇注到模具中，将模具中的混凝土养护后进行脱模、切割坯体，对坯体进行高温高压蒸汽养护，即可制得蒸压加气混凝土。本申请的利用炉底渣制备的蒸压加气混凝土具有解决蒸压加气混凝土吸水性强的问题的优点。
