Curing agent for original-state shield muck roadbed material, roadbed material and preparation method of roadbed material
The invention relates to a curing agent for an original-state shield muck roadbed material, the roadbed material and a preparation method of the roadbed material. The curing agent comprises the following raw materials in percentage by mass: 60-92% of an alkali-activated cementing material, 1-12% of stone powder, 5-18% of gypsum and 1-10% of an additive, the use amount of the curing agent accounts for 1%-15% of the mass of the roadbed material; the invention further discloses a preparation method of the shield muck solidified roadbed material. The preparation method comprises the following steps: uniformly mixing and stirring the curing agent and the shield muck, and then paving and backfilling; after the shield muck roadbed material is cured, the 3d strength exceeds 1.5 MPa, the 7d strength exceeds 3.0 MPa, and the curing strength of the shield muck roadbed material is more than three times that of cement with the same mixing amount. The curing agent is low in mixing amount, high in curing strength, low in curing cost and wide in application scene, and shield muck can be treated and recycled on a large scale.
本发明涉及一种原状盾构渣土路基材料的固化剂、路基材料及其制备方法，所述固化剂包括如下质量百分比的原料：碱激发胶凝材料60％‑92％、石粉1％‑12％、石膏5％‑18％和外加剂1％‑10％；所述固化剂用量占所述路基材料质量的1％‑15％；本发明还包括该盾构渣土固化路基材料的制备方法，通过将固化剂与盾构渣土混合搅拌均匀后摊铺、回填；本发明的盾构渣土路基材料，经固化后3d强度超过1.5MPa，7d强度超过3.0MPa，是同等掺量水泥固化强度的3倍以上。本发明固化剂掺量低、固化强度高、固化成本低、应用场景广泛，可大规模处置与资源化利用盾构渣土。
