Abstract
A series of studies aims to develop superabsorbent polymer based soil conditioner as new soil conditioner in classification sorting treatment of decontamination soil. In this study, the soil improvement mechanism by superabsorbent polymer based soil improvement material is verified through physical analysis. As a result, the following contents were revealed. (1) Improvement effect by superabsorbent polymer-based soil improving material is remarkable for any target soil, and in case of homogeneous soil, improving effect can be expected more in high water content condition. (2) Superabsorbent polymer based soil conditioner is an improvement based only on moisture absorption of interstitial water. (3) One of the reasons why the classification test results differ between sandy soil and viscous soil is that moisture having a high holding power remains in the viscous soil which can not be absorbed by the superabsorbent polymer type soil improving material, and the aggregate structure is dispersed. It could be thought that it did not reach to.
