Geopolymer high-strength mortar for repairing concrete structure and preparation method thereof
The invention discloses geopolymer high-strength mortar for repairing a concrete structure and a preparation method thereof. The geopolymer high-strength mortar is prepared from a component A and a component B. The component A is prepared from industrial solid waste as a main raw material and is obtained by mixing mineral powder, metakaolin, fly ash, graded sand, steel fibers or high-elastic-modulus organic fibers, and the component B is a composite alkaline activator; the component B is prepared by mixing sodium silicate, sodium hydroxide and water, and the product is obtained by uniformly mixing and stirring the component A and the component B in parts by weight. Compared with the prior art, the structure repairing material provided by the invention has the advantages of high bonding strength, good volume stability, convenient material taking, simple preparation process, non-toxic raw materials, low material cost, good durability and the like. The production and preparation process is simple, construction is convenient, and cost performance is excellent. A considerable proportion of industrial solid wastes are used, so that the preparation cost is reduced, and the environment isprotected.
本发明公开了一种混凝土结构修补用地质聚合物高强砂浆及其制备方法，由A、B两种组份制成,所述A组份以工业固体废弃物作为主要原料，由矿粉、偏高岭土、粉煤灰、级配砂、钢纤维或高弹模有机纤维混合得到，所述B组份为复合碱性激发剂，由水玻璃、氢氧化钠和水混合制备得到，将A、B两种组份按重量份数均匀混合搅拌后即得产品。与现有技术相比，本发明比现有的结构修补材料，粘接强度高、体积稳定性好，还具有取材方便、制备工艺简单、原材料无毒性及材料成本低、耐久性良好等优点。生产制备工艺简单、施工方便、性价比优越。使用了相当比例的工业固体废弃物，不仅降低了制备成本还有利于保护环境。
