The invention discloses a soil stabilization grouting material, belongs to the field of building construction materials, particularly relates to the technical field of grouting materials, aims to overcome the defects of poor concrete fluidity and poor shield soil stabilization effect in the prior art, and comprises the following components in parts by weight: 160-240 parts of cement, 42-58 parts of superfine powder, 700-780 parts of calcium carbonate and 7-13 parts of a core material. The preparation method of the soil stabilization grouting material comprises the following steps: step 1, mixing bentonite, a water reducing agent, a porous carrier and a suspending agent in parts by weight to prepare the core material; and step 2, mixing the cement, the superfine powder, the calcium carbonate and the core material according to the parts by weight to obtain the product. The grouting material is good in liquidity, small in expansion rate, good in shield soil stabilization effect and capable of replacing concrete, and subsequent component construction and installation are efficient and convenient.
本发明公开了一种稳土注浆料，属于建筑施工材料领域，具体涉及注浆料技术领域，按重量份数计，以解决现有的混凝土流动性差，盾构稳土效果差的缺陷，按重量份数计，包括如下组分，水泥160‑240份，超微粉42‑58份，碳酸钙700‑780份，核心料7‑13份。上述稳土注浆料的制备方法包括如下步骤：步骤1、按上述重量份，将膨润土、减水剂、多孔载体及悬浮剂混合制成核心料；步骤2、按上述重量份，将水泥、超微粉、碳酸钙及核心料的混合物一起混合，即得。本申请的注浆料流动性好，膨胀率小，盾构稳土效果好，可替代混凝土，后续构件施工安装高效方便。
