Autoclaved sand aerated concrete composition, building block and preparation method
The invention relates to the technical field of building materials, in particular to an autoclaved sand aerated concrete composition, a building block and a preparation method. The autoclaved sand aerated concrete composition comprises iron tailing sand, quick lime, a geopolymer material and desulfurized gypsum, the content of SiO2 in the iron tailing sand is greater than or equal to 80wt%; the ratio of calcium to silicon in the autoclaved aerated concrete composition is 0.19 to 0.61; the proportion of the iron tailing sand is 50-79wt%; the proportion of the quick lime is 11-27wt%; the ratio of the geopolymer material is 8-26 wt%; the desulfurized gypsum accounts for 1-4wt%; the geopolymer material comprises 15-25 wt% of gypsum, 35-50 wt% of mineral powder, 10-20 wt% of red mud, 15-25 wt% of fly ash and 0.5-2 wt% of an exciting agent, and the exciting agent comprises one or more of carbide slag, alkaline residues and lime. According to the invention, the emission of CO2 is reduced.
本发明涉及建筑材料技术领域，具体涉及一种蒸压砂加气混凝土组合物、砌块及制备方法。该蒸压砂加气混凝土组合物包括铁尾矿砂、生石灰、地质聚合物材料和脱硫石膏；铁尾矿砂中SiO2的含量≥80wt%；蒸压砂加气混凝土组合物中钙硅比为0.19‑0.61；铁尾矿砂占比50‑79wt%；生石灰的占比为11‑27wt%；地质聚合物材料的占比为8‑26wt%；脱硫石膏占比1‑4wt%；地质聚合物材料包括15‑25wt％的石膏、35‑50wt％的矿粉、10‑20wt％的赤泥、15‑25wt％的粉煤灰和0.5‑2wt％的激发剂，其中，激发剂包括电石渣、碱渣和石灰中的一种或多种。本发明减少了CO2的排放。
