Premixed mortar based on undisturbed shield muck as well as preparation method and application thereof
The invention relates to ready-mixed mortar based on undisturbed shield muck as well as a preparation method and application of the ready-mixed mortar. The ready-mixed mortar comprises the following raw materials in percentage by mass: 60-85% of undisturbed shield muck, 10-40% of an alkali-activated cementing material, 0.5-3% of an acrylate gel material, 1-10% of cement and 3-15% of water, the ready-mixed mortar provided by the invention can be instantly blended, solves the problem of time connection between the shield muck tapping material and on-site use, is convenient in on-site construction and good in operability, has relatively high compressive strength, excellent impermeability and water retention performance, small apparent density and low preparation cost, and realizes the purpose of turning waste into wealth. The invention provides a new method for large-scale treatment and resource utilization of the shield muck, and has important economic benefits, environmental benefits and social benefits.
本发明涉及一种基于原状盾构渣土的预拌砂浆及其制备方法和应用，该预拌砂浆包括如下质量百分比的原料：原状盾构渣土60％‑85％、碱激发胶凝材料10％‑40％、丙烯酸盐凝胶材料0.5％‑3％、水泥1％‑10％和水3％‑15％；本发明提供的预拌砂浆可即时调配，解决了盾构渣土出渣料与现场使用之间的时间衔接问题，现场施工方便、可操作性好，且预拌砂浆具有较高的抗压强度、抗渗性与保水性能优异、表观密度小，制备成本低，实现“变废为宝”。本发明为大规模处置与资源化利用盾构渣土提供了一种新方法，具有重要的经济效益、环境效益和社会效益。
