| 摘 要： | 以水泥、石灰和粉煤灰为固化材料,按照正交方法设计配合比,进行了淤泥的固化试验,通过测试固化淤泥的颗粒级配及含水率,研究了淤泥固化后其颗粒粒径分布及含水率的变化,探讨了固化材料中的各组分对淤泥固化效果的影响。结果发现,粉煤灰最有利于淤泥内部自由水和吸附水的减少,而石灰对于增大粒径效果最明显。淤泥经化学固化后,粘粒含量从34%降低到1%以下,强度稳定性和耐水性大大提高。

| Abstract: | According to orthogonal experimental design, the experiments of chemical solidification of dredged sediment are carried out using cement, lime and fly ash as solidification additives in this paper. The size distribution and the water content of the solidified sediment are tested, and the influence of each solidification additive on the solidification is analyzed. It shows that fly ash is most helpful to reduce the water in the sediment. However the slim is most useful to increase the size of the particles of the sediment. It is found that after chemical solidification, the content of the clay decreases from 34% to 1%, the strength stability and water resistance are enhanced. |
