Fly ash geopolymer grouting material suitable for reinforcing weak surrounding rock
The invention discloses a fly ash geopolymer grouting material suitable for weak surrounding rock reinforcement, and relates to the technical field of grouting materials, the grouting material comprises, by weight, 70-100 parts of fly ash, 30-60 parts of slag powder, 70-100 parts of water, and 10-20 parts of modified microspheres, the modified microspheres comprise shells and core materials coated by the shells, and the core materials are coated by the shells. The core material comprises rubber powder, anhydrous sodium sulphate, sodium carbonate and slaked lime. The exciting agent is wrapped in the microspheres and used for exciting the high-dosage fly ash geopolymer grouting material, and the exciting agent is not in contact with components outside the microspheres when the grouting material is prepared, so that the slurry flowability and stability of the fly ash geopolymer grouting material cannot be influenced. The modified microsphere excited high-volume fly ash geopolymer grouting material provided by the invention has the advantages of controllable setting time and good consolidation effect, and can solve the problems of inconvenient construction, unstable use effect and the like of the existing fly ash grouting material.
本发明公开了一种适用于软弱围岩加固的粉煤灰地聚物注浆材料，涉及注浆材料技术领域，按照重量份计，所述注浆材料包括粉煤灰70～100份，矿渣粉30～60份，水70～100份，改性微球10～20份，所述改性微球包括壳体及被壳体包覆的核材，所述核材包括胶粉、元明粉、碳酸钠和熟石灰。本发明将激发剂包裹在微球内部，用于激发高掺量粉煤灰地聚物注浆材料，在制备注浆材料时激发剂不与微球外部的组分接触，因而不会影响粉煤灰地聚物注浆材料的浆液流动性与稳定性。本发明提供的改性微球激发高掺量粉煤灰地聚物注浆材料具有凝结时间可控、固结效果好的优势，可解决现有的粉煤灰注浆材料施工不便、使用效果不稳定等问题。
