| 摘 要： | 采用燃煤电厂通过脱硫工序产生的脱硫灰、脱硫石膏及水泥对白马湖淤泥进行固化试验。抗压强度结果表明,淤泥中单掺水泥时,固化土强度随水泥掺量的增加而增加;水泥、脱硫灰和脱硫石膏三者复掺时,总掺量一定时,三者的最优比例为6:3:1,此时强度最佳且高于水泥单掺的强度。此外,还借助SEM对水泥-脱硫灰-脱硫石膏固化淤泥质土的机理进行了探讨。

| Abstract: | Using desulphurization ash generated by desulphurization process of thermal power plant, des.ulphurized gypsum and ce- ment to solidify the sullage of Baima Lake in experiment. The compressive strength results showed that when cement was added only, with the cement content climbing, the compressive strength increased; and when the three of them were added together and the total content was fixed, the best proportion of them was 6：3：1, and at the ratio the strength of solidified sullage was higher than that of the ce- ment-enhancing sullage; additionally, the solidifying mechanism of desulphurization ash-desulfurized-eement sullage was discussed. |
