High-strength and high-toughness geopolymer material and preparation method thereof
The invention discloses a high-strength and high-toughness geopolymer material. The high-strength and high-toughness geopolymer material comprises, by weight, 500-700 parts of silicon-aluminum mineralraw materials, 600-800 parts of an alkali activator, 70-150 parts of a nanoscale efficient modifier, 2-5 parts of super absorbent resin, 2-6 parts of a hybrid fiber, 4-10 parts of a surfactant, 700-1000 parts of fine aggregates and 100-150 parts of deionized water, the silicon-aluminum mineral raw materials comprise 200-300 parts of metakaolin, 150-200 parts of fly ash, 50-100 parts of red mud, 40-60 parts of mineral slag, 40-60 parts of silica fume and 20-40 parts of Portland cement, and the nanoscale efficient modifier comprises 20-50 parts of condensed phosphate, 20-40 parts of nano-silica, 20-40 parts of nano-alumina and 10-20 parts of zeolite. The invention further discloses a preparation method of the high-strength and high-toughness geopolymer material. The problems of large earlyself-shrinkage and easy cracking of the geopolymer are solved, and the obtained geopolymer has strong toughness and high strength.
本发明公开了一种高强高韧地聚合物材料，包括以下按重量计的组分：硅铝质矿物原料500‑700份，碱激发剂600‑800份，纳米级高效改性剂70‑150份，高吸水性树脂2‑5份，混杂纤维2‑6份，表面活性剂4‑10份，细骨料700‑1000份，去离子水100‑150份，硅铝质矿物原料包括偏高岭土200‑300份、粉煤灰150‑200份、赤泥50‑100份、矿渣40‑60份、硅灰40‑60份和硅酸盐水泥20‑40份，纳米级高效改性剂包括缩合磷酸盐20‑50份、纳米二氧化硅20‑40份、纳米氧化铝20‑40份、沸石10‑20份。本发明还公开了高强高韧地聚合物材料制备方法。本发明解决了地聚合物早期自收缩大、易开裂的问题，得到的地聚合物有较强的韧性和较高的强度。
