Autoclaved aerated concrete slab and preparation method thereof
The invention discloses an autoclaved aerated concrete slab and a preparation method thereof. The invention relates to the technical field of autoclaved aerated concrete. The problems that the overallstructure of autoclaved aerated concrete is damaged due to the fact that external water easily permeates into the micropore structure of the autoclaved aerated concrete and is accumulated, and a long-time water erosion effect is easily generated on the autoclaved aerated concrete is solved. The autoclaved aerated concrete slab comprises the following components in parts by weight: 110-130 parts of lime, 140-160 parts of cement, 670-690 parts of mining and beneficiation waste residues, 50-60 parts of desulfurized gypsum, 8-14 parts of aluminum powder, 3-5 parts of an anti-settling agent, 1-2 parts of an expanding agent, 6-9 parts of brittle reinforced fibers, 1.5-2.5 parts of a water reducing agent, 3-6 parts of activated carbon fiber, 3-5 parts of diatomite, 1-3 parts of metakaolin, 280-320 parts of water. The autoclaved aerated concrete slab disclosed by the invention can keep the stability of the overall structure for a long time in a high-humidity environment, and is excellent in water erosion resistance and good in overall application effect.
本发明公开了一种蒸压加气混凝土板及其制备方法，涉及蒸压加气混凝土技术领域，解决了因外界水分容易渗入到蒸压加气混凝土的微孔结构中并蓄积起来，而容易对蒸压加气混凝土产生长时间的水蚀作用，进而导致蒸压加气混凝土整体结构被破坏的问题，其中，一种蒸压加气混凝土板包括如下重量份数的组分：石灰110‑130份；水泥140‑160份；采矿选矿废渣670‑690份；脱硫石膏50‑60份；铝粉8‑14份；防沉剂3‑5份；膨胀剂1‑2份；脆性增强纤维6‑9份；减水剂1.5‑2.5份；活性炭纤维3‑6份；硅藻土3‑5份；偏高岭土1‑3份；水280‑320份。本发明中的蒸压加气混凝土板在高湿环境中能较长时间保持整体结构的稳定，抗水蚀效果优异，整体应用效果好。
