Abstract

Abstract

In order to study the influencing factors of moisture content and permeability of the consolidated body in the process of chemical consolidation treatment of waste slurry, super absorbent polymer (SAP) and cement were selected as the consolidation materials, and indoor consolidation tests were carried out on the waste mud to study different consolidations. The effects of materials, material ratios, and consolidation time on moisture content of the consolidated body were tested on a permeation instrument modified from a medium pressure filter loss instrument, to study the effects of the above factors on permeability. The results showed that SAP over 5% in 24 hours was better in reducing moisture content than cement, and after 168 h, cement with the same ratio was better than SAP. The permeability of the SAP group was better than that of the cement group, and the ratio was increased to 7%. After the consolidation time reached 72 h, the permeability of the SAP group didn’t continue to decrease but increased. When the cement ratio was below 7%, when increasing the ratio to permeability, the effect of sexual blocking became more significant. After analysis, there was a positive correlation between the permeability of the consolidated body and the moisture content, and the moisture content affected the permeability by changing the number of seepage channels. 5% SAP and 7% cement made the waste slurry achieve a better consolidation effect.
