Fly ash-based high-freezing-resistance geopolymer concrete and preparation process thereof
The invention discloses fly ash-based high-freezing-resistance geopolymer concrete and a preparation process thereof, and belongs to the technical field of concrete.The fly ash, furnace slag and desulfurized gypsum serve as raw materials, sodium silicate and cement are adopted to excite the raw materials at the same time, C30-C60 concrete is prepared, and the freezing resistance of the geopolymer concrete is improved. A proper cement mixing amount is adopted, high-activity materials such as fly ash and slag react with sodium hydroxide and water glass under the alkaline condition to form a compact C (A) SH gel structure, the freeze-thaw cycle durability of the concrete can be effectively enhanced, and particularly in an extreme salt freezing environment, crack generation and expansion are effectively delayed, and the concrete has the advantages of being high in strength, good in durability and good in durability. And the long-term service performance of the material is further improved.
本发明公开了一种粉煤灰基高抗冻性地聚合物混凝土及其制备工艺，属于混凝土技术领域，本发明通过粉煤灰、炉渣、脱硫石膏作为原材料，采用水玻璃和水泥对这些原材料进行同时激发，进行C30‑C60混凝土的制备，提高地聚合物混凝土抗冻性能。本发明采用适当的水泥掺量，使高活性材料如粉煤灰、矿渣，在碱性条件下与氢氧化钠和水玻璃反应，形成密实的C(A)SH凝胶结构，能有效增强混凝土的冻融循环耐久性，特别是在极端的盐冻环境中，有效延缓裂缝生成和扩展，进而提高了材料的长期服务性能。
