Shield grouting material dry powder composition, pneumatic shield grouting material dry powder, and preparation method and use method of pneumatic shield grouting material dry powder
The invention relates to the technical field of building materials, and discloses a shield grouting material dry powder composition, pneumatic shield grouting material dry powder, and a preparation method and a use method thereof. The composition contains cement clinker, fluorgypsum, mineral slag, steel slag, modified bentonite, a sand powder composition and an exciting agent which are stored independently or stored in a mixed mode of two or more of the cement clinker, the fluorgypsum, the mineral slag, the steel slag, the modified bentonite, the sand powder composition and the exciting agent. The shield grouting material provided by the invention has the advantages of good fluidity, strong layering bleeding resistance and high consolidation rate; the shield grouting material prepared by the method can consume a large amount of solid waste, reduces the use amount of cement, and has remarkable environmental benefits; in addition, in a construction site, a dry powder pneumatic conveying mode can be adopted to replace long-distance liquid material conveying, the risk of slurry pressure bleeding is remarkably reduced, the project quality is ensured, meanwhile, the length of a cleaning pipeline is reduced, and the water-saving effect is achieved.
本发明涉及建筑材料技术领域，公开了一种盾构注浆料干粉组合物、可气送盾构注浆料干粉及其制备方法和使用方法。该组合物中含有各自独立地保存或两者以上混合保存的以下组分：水泥熟料、氟石膏、矿渣、钢渣、改性膨润土、砂粉组合和激发剂。本发明提供的盾构注浆料具有流动性好、抗分层泌水能力强、固结率高；采用本发明方法制备盾构注浆料能够消纳大量固体废弃物，减少水泥的使用量，环境效益显著；另外，施工现场能够采用气送干粉方式替代长距离输运液料，显著降低浆体压力泌水的风险，确保工程质量，同时减少清洗管道长度，具有节水效果。
