Shield grouting material and preparation method thereof
The invention relates to a grouting material, and discloses a shield grouting material which comprises cement, high-calcium fly ash, fine sand, bentonite, metakaolin, iron tailings, an alkaline activator and a water reducing agent. On the basis that the weight part number of the cement is 1, the shield grouting material contains the following components in parts by weight: 3 to 7 parts of high-calcium fly ash, 1 to 2.5 parts of fine sand, 0.1 to 0.8 part of bentonite, 0.2 to 1 part of metakaolin, 1 to 1.5 parts of iron tailings, 0.1 to 0.4 part of alkaline activator and 0.003 to 0.05 part of water reducing agent. In addition, the invention also discloses a preparation method of the shield grouting material. The shield grouting material disclosed by the invention is high in consolidation rate, high in squaring rate and good in construction effect.
本发明涉及注浆材料，公开了一种盾构注浆材料，包括水泥、高钙粉煤灰、细沙、膨润土、偏高岭土、铁尾矿、碱性激发剂和减水剂，以所述水泥的重量份为单位1计，所述盾构注浆材料含有3‑7重量份的高钙粉煤灰、1‑2.5重量份的细沙、0.1‑0.8重量份的膨润土、0.2‑1重量份的偏高岭土、1‑1.5重量份的铁尾矿、0.1‑0.4重量份的碱性激发剂和0.003‑0.05重量份的减水剂。另外本发明还公开了一种盾构注浆材料的制备方法。本发明的盾构注浆材料固结率高，出方率高，施工效果好。
