High-toughness and high-durability geopolymer hydraulic anti-abrasion material and preparation method thereof
The invention discloses a high-toughness and high-durability geopolymer hydraulic anti-abrasion material which comprises the following raw materials in parts by weight: 36-42 parts of fly ash, 7-9 parts of calcined metakaolin, 4-5 parts of Portland cement, 2-3 parts of silica fume, 2-3 parts of nano silicon dioxide, 15-19 parts of fine aggregate (natural river sand, carborundum and rubber particles in a ratio of 4.5: 4.5: 1), 0.5-1 part of water and 26-29 parts of water glass. 2-3 parts of sodium hydroxide, 1.2-1.8 parts of polyvinyl alcohol fiber and 0.4-0.6 part of polyvinyl alcohol powder. The high-toughness and high-durability geopolymer hydraulic erosion and abrasion resistant material disclosed by the invention has better toughness, impact resistance and abrasion resistance, and compared with a traditional material, the material disclosed by the invention shows better durability in water flow impact, impact and abrasion environments, so that the sustainability of a project is improved; in addition, the geopolymer serving as a main cementing material is more energy-saving and environment-friendly, and construction, popularization and application are easy by adopting normal-temperature maintenance.
本发明公布了一种高韧性、高耐久性地聚合物水工抗冲磨材料，原料组成按重量份数计如下：粉煤灰36‑42份，煅烧偏高岭土7‑9份，硅酸盐水泥4‑5份，硅灰2‑3份，纳米二氧化硅2‑3份，细骨料(天然河砂:金刚砂:橡胶颗粒=4.5:4.5:1)15‑19份，水0.5‑1份，水玻璃26‑29份，氢氧化钠2‑3份，聚乙烯醇纤维1.2‑1.8份，聚乙烯醇粉末0.4‑0.6份。本发明的高韧性、高耐久性地聚合物水工抗冲磨材料具有较好的韧性、抗冲击和抗磨蚀性能，相较于传统材料，本发明的材料在水流冲击、撞击和磨蚀环境下表现出更佳的耐久性，提高了工程的可持续性；此外，以地聚合物作为主要胶凝材料更加节能环保，采用常温养护易于施工和推广应用。
