Preparation method of novel composite cement-based grouting material
The invention belongs to the technical field of preparation of cement-based grouting materials, and particularly relates to a preparation method of a novel composite cement-based grouting material, which comprises the following steps: adding a proper amount of limestone into a mixture, adding a water reducing agent, uniformly stirring, finally adding carbon nanotubes, adding distilled water while stirring until the mixture has proper flowability, uniformly stirring, and cooling to room temperature to obtain the novel composite cement-based grouting material. Step 2, slowly adding a proper amount of a slurry reinforcing agent into the second mixture generated in the step 2, uniformly stirring, adding a stabilizer into the mixture obtained in the step 3, and synchronously stirring to form an adsorption hydration layer; the compressive strength and the tensile strength of the novel composite cement-based grouting material are both improved, in addition, a stabilizer is added into the composite grouting material, an adsorption hydration layer is formed, cement particles are bridged to form a net structure, and the stability of grout is further improved.
本发明公开的属于水泥基注浆材料制备技术领域，具体为一种新型复合水泥基注浆材料的制备方法，包括混合体内加入适量石灰石，并加入减水剂并搅拌均匀，最后加入纳米碳管，边搅拌边用蒸馏水加入至适宜的流动性，搅拌至均匀，生成第二混合体，向步骤二生成的第二混合体内缓慢加入适量浆液增强剂，搅拌均匀，向步骤三的混合体内部添加稳定剂，并同步搅拌，形成吸附水化层，通过添加适宜的碳纳米管及玻璃纤维含量下，使得新型复合水泥基注浆材料的抗压强度和抗拉强度均有所提升，并且，在复合注浆材料内加入稳定剂，形成吸附水化层，将水泥颗粒桥接形成网状结构，进一步提高浆液稳定性。
