Large-span high-performance unreinforced autoclaved aerated concrete plate and preparation method thereof
The invention relates to a large-span high-performance unreinforced autoclaved aerated concrete plate and a preparation method thereof. The large-span high-performance unreinforced autoclaved aerated concrete plate comprises the following components in parts by mass: 450-600 parts of a siliceous material; 150 to 250 parts of a cementing material; 250 to 400 parts of a calcium material; 20 to 40 parts of desulfurized gypsum; 50 to 250 parts of a polymer monomer; 0.5 to 6 parts of an initiator; 0.3 to 3 parts of a cross-linking agent; 1-15 parts of a foaming agent; 1-10 parts of a foam stabilizer; and 500 to 700 parts of water. The preparation method comprises the following steps: stirring and mixing all the components, and then carrying out curing and high-temperature autoclaved reaction to obtain the large-span high-performance unreinforced autoclaved aerated concrete plate. Compared with the prior art, the in-situ polymerization method is innovatively adopted, and the prepared plate has the advantages of high breaking strength, high compressive strength, low maintenance energy consumption, simple and convenient production operation steps and easiness in construction.
本发明涉及一种大跨度高性能无筋蒸压加气混凝土板材及其制备方法，该大跨度高性能无筋蒸压加气混凝土板材如下质量份数的组分：硅质材料450‑600份；胶凝材料150‑250份；钙质材料250‑400份；脱硫石膏20‑40份；聚合物单体50‑250份；引发剂0.5‑6份；交联剂0.3‑3份；发泡剂1‑15份；稳泡剂1‑10份；水500‑700份。其制备方法为将各组分搅拌混合后进行养护和高温蒸压反应，即得到大跨度高性能无筋蒸压加气混凝土板材。与现有技术相比，本发明创新性地采用了原位聚合的方法，制备的板材兼具高抗折强度、抗压强度，养护能耗低，生产操作步骤简便，易于施工。
