Modified raw soil material formula using cement and iron tailings
The invention discloses a formula of a modified immature soil material by using cement and iron tailings, which belongs to the technical field of immature soil and comprises the following raw materials in percentage: 12.1-13.5% of iron tailing sand with reasonable blending amount, 16.1-19.1% of cement with reasonable blending amount and 68.2-69.9% of immature soil with reasonable blending amount. According to the formula of the modified raw soil material using the cement and the iron tailings, the cement is hydrated to generate a large amount of products such as hydrated calcium silicate gel, and the iron tailings and plain soil are well coagulated together by the gel, so that the loose state of a soil body and iron tailing sand is stabilized; meanwhile, excessive gaps among soil particles in the test piece and between the soil particles and the iron tailing sand are filled with the gel, so that the compactness of the test piece is increased, and the external force resistance of the test piece is improved.
本发明公开了一种利用水泥及铁尾矿的改性生土材料配方，属于生土技术领域，包括如下百分比的原料：铁尾矿砂合理掺和量为12.1‑13.5％，水泥合理掺和量为16.1‑19.1％与生土合理掺和量为68.2‑69.9％。该利用水泥及铁尾矿的改性生土材料的配方，水泥水化产生大量的水化硅酸钙凝胶等产物，凝胶将铁尾矿以及素土很好的凝结在一起，稳固了土体与铁尾矿砂松散状态，同时凝*胶填充了试件内部土颗粒间以及土颗粒与铁尾矿砂间多余空隙，增加了试件的密实度，提高了试件抵抗外力的能力。
