Unfired ultralight aggregate
The invention relates to the field of building materials, in particular to an unfired ultralight aggregate. The unfired ultralight aggregate is prepared from the following raw materials in parts by mass: 100 parts of fly ash, 50-100 parts of expanded perlite, 150-200 parts of water glass (solid content of 30%), 1-2 parts of a water glass curing agent and 3-10 parts of a water repellent emulsion (solid content of 1-5%). According to the unfired ultra-light aggregate, the water glass and the fly ash are utilized to form a geopolymer, and a spatial network structure is formed; meanwhile, the water glass curing agent is added to be combined with the water glass to form a consolidated body, so that the high mechanical strength of the unfired ultra-light aggregate is improved. The unfired ultralight aggregate is high in compressive strength, low in water absorption and small in volume weight.
本发明涉及建筑材料领域，具体涉及一种免烧超轻骨料。一种免烧超轻骨料，由如下质量份的原料制备而成：粉煤灰100份，膨胀珍珠岩50‑100份，水玻璃(30％固含量)150‑200份，水玻璃固化剂1‑2份，憎水剂乳液(1‑5％固含量)3‑10份。本发明的免烧超轻骨料利用水玻璃与粉煤灰形成地质聚合物，形成空间网络结构；同时添加水玻璃固化剂与水玻璃结合，形成固结体，提高了免烧超轻骨料较高的机械强度。本发明的免烧超轻骨料抗压强度高、吸水率低、容重小。
