Geopolymer material suitable for repairing road interlayer void disease and preparation method of geopolymer material
The invention discloses a geopolymer material suitable for repairing road interlayer void diseases and a preparation method of the geopolymer material, and belongs to the technical field of cementing materials. The geopolymer material disclosed by the invention is prepared by taking slag and fly ash as main raw materials, adding a proper amount of VAE rubber powder, an air entraining agent and a concrete expansive agent, and then performing geopolymerization reaction under excitation of modified water glass with modulus adjusted by NaOH. The geopolymer material has the advantages of good fluidity, high early strength and micro-expansion, and the breaking strength and toughness of the geopolymer material are remarkably improved compared with those of existing materials. In addition, the geopolymer material and the preparation method are simple and easy to operate, and the geopolymer material has high practicability and economical efficiency and can be widely applied to repair of road interlayer void diseases.
本发明公开了一种适用于道路层间脱空病害修复的地聚合物材料及其制备方法，属于胶凝材料的技术领域。本发明所公开的地聚合物材料是以矿渣、粉煤灰为主要原料，同时添加有适量VAE胶粉、引气剂、混凝土膨胀剂，再通过加入NaOH调节模数后的改性水玻璃的激发下进行地聚合反应产生的。该地聚合物材料具有流动性好、早期强度高、微膨胀的优点，抗折强度和韧性相比现有材料有显著提高。另外，该地聚合物材料，制备方法简单易操作，具有较强的实用性与经济性，可广泛应用于适用于道路层间脱空病害的修复。
