Shield muck lightweight treatment solidified soil as well as preparation method and application thereof
The invention relates to the technical field of building engineering materials, and provides shield muck lightweight treatment solidified soil as well as a preparation method and application thereof. Shield muck, a cementing material, aggregate, an exciting agent and an additive are mixed according to a specific proportion to prepare solidified soil, and efficient and rapid solidification of the solidified soil is guaranteed through the coordination effect of all the components. A cementing material is used as a curing agent, fine sand is used as aggregate, and the strength of the solidified soil material is comprehensively improved; the strength and durability of the material are remarkably improved by utilizing the muck activator; the foaming agent is used for generating bubbles in the material as a main means for light weight. The cementing material is mixed and foamed with foams prepared by the foaming agent, water and soil particles in mud are fully coagulated and hardened through physical and chemical actions to form a firm and compact structure, the porosity, the water content and the compressibility of the treated shield muck solidified soil are reduced, the strength and the stability of the shield muck solidified soil are remarkably improved, and the shield muck solidified soil has the advantages of being high in strength and good in stability. Therefore, the purposes of light weight and high strength are achieved.
本发明涉及建筑工程材料技术领域，提供了一种盾构渣土轻质化处理固化土及其制备方法和应用。将盾构渣土、胶凝材料、骨料、激发剂和外加剂按照特定的比例混合制成固化土，通过各组分间的协调作用，保证其高效快速固化。利用胶凝材料作为固化剂，细砂作为骨料，综合提升固化土材料的强度；利用渣土活性剂显著提升材料的强度和耐久性；利用发泡剂在材料内部生成气泡，作为轻量化的主要手段。胶凝材料通过与发泡剂制备的泡沫一起混合发泡，经物理、化学作用，泥状物中的水、土颗粒充分凝结硬化进而形成坚固且紧密的结构，处理后的盾构渣土固化土孔隙率下降，含水率降低，压缩性减小，其强度和稳定性都得到了显著的增加，从而实现轻质、高强的目标。
