Tunnel grouting material and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to a tunnel grouting material and a preparation method thereof.The tunnel grouting material is prepared by adopting cement as a cementing material, adding a large amount of industrial solid waste as an admixture, modifying steel slag to prepare semi-carbonized steel slag powder, and matching with phosphorus slag powder, carbide slag and desulfurized fly ash as the admixture. According to the preparation method, the water reducing agent and the SAP particles are added as additives, all the raw materials cooperate with one another, the grouting material which is good in flowability, compactness and mechanical property, has a long-term expansion effect in a humid environment and is good in sealing and anti-seepage effect is prepared, and efficient utilization of industrial solid waste is achieved at the same time.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种隧道注浆材料及其制备方法，本发明采用水泥作为胶凝材料，添加大量工业固废作为掺合料，其中，通过对钢渣进行改性制备半碳化钢渣粉，并配合磷渣粉和电石渣、脱硫灰作为掺合料，添加减水剂和SAP颗粒作为外加剂，各原料相互协同，制备得到具有良好流动性、密实性、力学性能，同时具备潮湿环境长期膨胀效果、密封抗渗效果良好的注浆材料，同时实现工业固废的高效利用。
