摘要
为高效处理高含水率疏浚淤泥,提出将高含水率疏浚淤泥进行流动固化处理,并对"固化土拌合物"的流动性和固化土强度进行了试验研究。结果表明,疏浚淤泥初始含水率、固化剂掺量、放置时间对"固化土拌合物"的流动性均有很大影响;同时试验亦表明疏浚淤泥固化土具有较高的抗压强度,添加磷石膏对水泥固化土具有明显的增强作用。
In order to deal with the dredged clays with high water content efficiently, a new idea as solidifying in flowing state is put forward. Some experiments are clone to study the fluidity of the mixture and the strength of solidified soil. The results show that the initial water content,the addition quantity of solidification agent and the time are the three important influential factors. The results of strength tests indicate that the unconfined compression strength of solidified soil is relatively high and phosphogypsum is very useful for the improvement of the strength of solidified soil.
