Lightweight aggregate geopolymer foam concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to lightweight aggregate geopolymer foam concrete and a preparation method thereof, the lightweight aggregate geopolymer foam concrete comprises the following components by mass: 210-245 parts of fly ash, 105-140 parts of mineral powder, 120-130 parts of a sodium silicate solution, 120-130 parts of a sodium hydroxide solution, 16-22 parts of polystyrene foam particles, and 17-20 parts of prefabricated foam. The prefabricated foam is prepared by injecting compressed air into a foaming agent solution, and the foaming agent solution comprises an anionic surfactant, polyvinyl alcohol, sodium hydroxide particles, nanometer aluminum oxide particles and deionized water. The foam concrete has the advantages of being low in cost, free of cement, light in weight, good in heat preservation performance, good in durability and the like, and the problems that foam concrete is high in carbon emission, unstable in foaming agent and the like can be effectively solved.
本发明属于建筑材料技术领域，尤其涉及一种轻骨料地聚物泡沫混凝土及其制备方法，按质量份计包括以下组分：粉煤灰210‑245份，矿粉105‑140份，硅酸钠溶液120‑130份，氢氧化钠溶液120‑130份，聚苯乙烯泡沫颗粒16‑22份，预制泡沫17‑20份。预制泡沫通过将压缩空气注入到发泡剂溶液中制得，所述发泡剂溶液的组分包括阴离子表面活性剂、聚乙烯醇、氢氧化钠颗粒、纳米氧化铝颗粒和去离子水。本发明的有益效果是：该泡沫混凝土具有成本低、无水泥、重量轻、保温性能好、耐久性能好等特点，能有效解决泡沫混凝土碳排放高、发泡剂不稳定等问题。
