Modified cement vertical barrier material and preparation method thereof
The invention discloses a modified cement vertical barrier material, which is prepared from the following raw materials in percentage by mass: 0.25 to 3.75 percent of modifier, 4.75 to 11.25 percent of cement, 5 to 15 percent of bentonite and 70 to 90 percent of in-situ soil. The invention discloses a preparation method of the modified cement vertical barrier material. The invention discloses a use method of the modified cement vertical barrier material. The obtained modified cement system vertical barrier material is excellent in sulfate corrosion resistance, can be applied to construction of an anti-seepage and anti-fouling barrier rich in sulfate leachate, guarantees the chemical stability of a barrier system, ensures the long-term service performance of a vertical barrier, and can be widely popularized and applied to anti-seepage and anti-fouling barrier projects rich in sulfate corrosion environments.
本发明公开了一种改性水泥系竖向阻隔材料，其原料按质量百分比包括：改性剂0.25‑3.75％，水泥4.75‑11.25％，膨润土5‑15％，原位土70‑90％。本发明公开了上述改性水泥系竖向阻隔材料的制备方法。本发明公开了上述改性水泥系竖向阻隔材料的使用方法。本发明所得改性水泥系竖向阻隔材料抗硫酸盐侵蚀性能优异，可应用于富含硫酸盐渗滤液的抗渗防污屏障建设，保障屏障体系化学稳定性，确保竖向屏障的长期服役性能，可大范围推广应用于富含硫酸盐侵蚀环境的抗渗防污屏障工程中。
