Controllable anti-seepage slurry and preparation method thereof
The invention discloses controllable anti-seepage slurry and a preparation method thereof. The controllable anti-seepage slurry is prepared from the following components in percentage by volume: 15-25% of cement, 3-6% of bentonite, 30-40% of clay, 15-25% of fly ash, a viscosity time-varying admixture accounting for 2-3.5% of the mass of the cement, and the balance of water, the viscosity time-varying admixture comprises a first admixture, a second admixture and a third admixture, and the mass percentages of the first admixture, the second admixture and the third admixture in the cement are respectively as follows: 0.3-0.5% of the first admixture, 0-2.5% of the second admixture and 0.5-1.5% of the third admixture. The viscosity time-varying admixture is used as an auxiliary material of the slurry, so that the flowability, viscosity, pumping period and setting time of the slurry are adjusted and controlled, various performance indexes of the anti-seepage slurry are optimal and can be controllably adjusted according to engineering conditions, and the prepared anti-seepage slurry is suitable for anti-seepage engineering of tailings ponds and refuse landfills.
本发明公开了一种可控的防渗浆液及其制备方法，由按照以下体积百分比配比的组分组成：水泥15～25％、膨润土3～6％、粘土30～40％、粉煤灰15～25％、占水泥质量百分比2～3.5％的粘度时变外掺剂、及余量的水；粘度时变外掺剂包括第一外掺剂、第二外掺剂和第三外掺剂，其质量占所述水泥的质量的百分比分别为：第一外掺剂0.3～0.5％、第二外掺剂0～2.5％、第三外掺剂0.5～1.5％。本发明使用粘度时变外掺剂作为浆液的辅料，实现对浆液流动性、粘度、可泵期、凝结时间的调节与控制，使防渗浆液的各项性能指标达到最优并根据工程条件进行可控调节，制得的防渗浆液适用于尾矿库和垃圾填埋场的防渗工程。
