Lightweight high-ductility geopolymer material and preparation method thereof
The invention discloses a lightweight high-ductility geopolymer material and a preparation method thereof. The lightweight high-ductility geopolymer material provided by the invention comprises the following preparation raw materials in parts by weight: 40 to 50 parts of fly ash, 10 to 15 parts of granulated blast furnace slag, 3 to 5 parts of metakaolin, 3 to 5 parts of silica fume, 5 to 15 parts of fly ash floating beads, 1 to 1.5 parts of PVA fibers, 0.1 to 0.15 part of multi-walled carbon nanotubes, 10 to 15 parts of deionized water, 15 to 20 parts of water glass, 2 to 4 parts of sodium hydroxide, and 0.2 to 0.4 part of a dispersing agent. Compared with a common geopolymer, the prepared lightweight high-ductility geopolymer material has the characteristics of high strength, high toughness, light weight and the like. The 28 d compressive strength of the prepared lightweight high-ductility geopolymer material reaches 30 MPa or above, the tensile strain reaches 6%, the volume weight is about 1500 kg/m<3>, and the lightweight high-ductility geopolymer material can be applied to the fields of engineering structure reinforcement technologies and the like.
本发明公开了一种轻质高延性地聚物材料及其制备方法。本发明提供的轻质高延性地聚物材料包括以下重量份的制备原料：粉煤灰40‑50份；粒化高炉矿渣10‑15份；偏高领土3‑5份；硅灰3‑5份；粉煤灰漂珠5‑15份；PVA纤维1‑1.5份；多壁碳纳米管0.1‑0.15份；去离子水10‑15份；水玻璃15‑20份；氢氧化钠2‑4份；分散剂0.2‑0.4份。本发明制备的轻质高延性地聚物材料相比与普通地聚物，具有高强度，高韧性，且更加轻质等特点。本发明制备的轻质高延性地聚物材料28d抗压强度达到30Mpa以上，拉伸应变达到6％，容重1500kg/m3左右，可运用于工程结构加固技术等领域。
