Slag-based shield tunnel backfill grouting material and preparation method thereof
The invention discloses a slag-based shield tunnel backfill grouting material and a preparation method thereof, and belongs to the field of tunnel construction materials and the field of comprehensive utilization of solid wastes. The grouting material is prepared from the following raw material components in parts by mass: 30 to 50 parts of blast furnace slag, 20 to 50 parts of fly ash, 5 to 20 parts of a blender, 80 to 110 parts of an exciting agent solution, 100 to 150 parts of recycled fine aggregate and 0.5 to 1 part of an additive. The grouting material is prepared by using the slag, the fly ash, the boric sludge and the coal gangue as cementing materials instead of cement, so that the production cost can be reduced, the environmental pollution can be reduced, the resource utilization of solid wastes can be realized, the strength can be improved, the impermeability and the stone rate of the grouting material can be increased, and the particle separation and water separation characteristics in the grouting material can be reduced.
一种矿渣基盾构隧道壁后注浆材料及制备方法，属于隧道施工材料领域和固体废弃物综合利用领域。所述注浆材料按质量份数计，原料包括以下组分:高炉矿渣30～50份、粉煤灰20～50份、调和剂5～20份、激发剂溶液80～110份、再生细骨料100～150份、外加剂0.5～1份。本发明采用矿渣、粉煤灰、硼泥、煤矸石作为胶凝材料替代水泥制备注浆材料，不仅能够降低生产成本、减少环境污染，实现固废的资源化利用，而且能提高强度，增加注浆材料的抗渗性和结石率，降低注浆材料内的颗粒分离和析水特性。
