Stabilization of poor soil by paper sludge mixing

摘要

Paper sludge absorbs much water contained in poor soil and stabilizes the soil quickly. Also,even if paper sludge is mixed with soils, there is no problem with soil environment. In this study, in order toclarify the influence of the paper sludge on stabilization, the poor soils mixed with paper sludge are investigatedby a series of laboratory tests. The following conclusions are obtained from the present study: (1) The tendencyof strength reduction of the soil mixed with paper sludge due to adding water fluctuates with changes in theactivity of the poor soil. (2) The tendency of strength recovery of the soil by paper sludge mixing is fluctuant withchanges in the poor soil. (3) If paper sludge is mixed with different soil with different activity, the interactionbetween fibers and soil particles is different.
