Activation method of shield muck graded fine silt and preparation method of grouting material
The invention provides an activation method of graded fine silt of shield muck and a preparation method of a grouting material, and the activation method comprises the following steps: drying the graded fine silt and then carrying out ball milling to obtain mechanically activated graded fine silt; taking graded fine silt after mechanical activation, adding alkaline residues and carbide slag into the graded fine silt, mixing, mixing NaOH with the mixture, and calcining in a muffle furnace to obtain a graded fine silt activation product; mixing NaOH with the graded fine silt subjected to mechanical activation, and roasting in a muffle furnace to prepare an alkali activator; mixing the alkali activator with slag, steel slag and fly ash to obtain a cementing material; and mixing the graded fine silt activated product with a cementing material, and then adding water for mixing to obtain the graded fine silt grouting material. The prepared grouting material is high in mechanical strength, in the process of preparing the grouting material, the physical and chemical properties of multiple solid wastes are utilized at the same time to achieve the synergistic effect, the multiple solid wastes are consumed, and the sustainable development concept of waste recycling is embodied.
本发明提出了一种盾构渣土分级细泥的活化方法及注浆材料的制备方法，包括以下步骤：将分级细泥烘干后进行球磨，得到机械活化后的分级细泥；取机械活化后的分级细泥，在其中加入碱渣、电石渣并混合，再将NaOH与上述混合物混合后置于马弗炉中煅烧，得到分级细泥活化产物；取NaOH与机械活化后的分级细泥混合后置于马弗炉中焙烧，制备出碱活化剂；将碱活化剂与矿渣、钢渣、粉煤灰混合后作为胶凝材料；将分级细泥活化产物与胶凝材料混合，再加入水混合，得到分级细泥注浆材料。本发明制得的注浆材料力学强度高，且在制备注浆材料过程中，同时利用多种固体废物理化性质协同作用，消纳了多种固体废物，体现了废物再利用的可持续发展理念。
