Shield grouting material and preparation method thereof
The invention relates to the technical field of building materials, in particular to a shield grouting material and a preparation method thereof. The shield grouting material is prepared from the following raw materials in parts by weight: 80 to 150 parts of ordinary cement, 1 to 5 parts of silica fume, 5 to 20 parts of bentonite, 50 to 150 parts of fly ash, 100 to 250 parts of machine-made sand, 500 to 750 parts of pretreated construction waste separated muck, 0 to 0.3 part of a water-retaining thickening agent, 0 to 3 parts of a water reducing agent and 500 to 650 parts of water. According to the shield grouting material, a large amount of pretreated construction waste separated muck is adopted as a raw material, use of natural fine sand and fly ash is reduced, the difficulty of resource utilization of the muck can be solved, consumption of the natural fine sand, the fly ash and the like is reduced, and the resource saving effect is remarkable.
本发明涉及建筑材料技术领域，尤其涉及一种盾构注浆料及其制备方法。盾构注浆料包括如下重量份数的原料：普通水泥80～150份、硅灰1～5份、膨润土5～20份、粉煤灰50～150份、机制砂100～250份、预处理后的建筑垃圾分离渣土500～750份、保水增稠剂0～0.3份、减水剂0～3份、水500‑650份。本发明的盾构注浆料中采用了大量的预处理后的建筑垃圾分离渣土作为原材料，减少了天然细砂和粉煤灰的使用，既可解决该渣土资源化利用困境，也减少了天然细砂、粉煤灰等的消耗，资源节约效果显著。
