| Outline of Final Research Achievements |
In this study, we experimentally examined how to efficiently collect the sludge generated in the disaster area, reduce the water content, increase the strength, and utilize it as ground materials for restoration. In the suppression of fluidity using waste polymer, it was found that the amount of added polymer that suppresses fluidity can be calculated if the consistency of the sludge is obtained. As a result of improving the collected sludge with waste gypsum board paper and cement, it was found that the improved soils have high strength and durability, and they can be used as excellent ground materials.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は災害現場で発生する厄介物の軟弱泥土を単に除去するのではなく，軟弱泥土を地盤材料に改良し，被災地の復旧・復興に貢献しようとするものである．研究の結果，おむつ工場から発生する廃ポリマーを用いて軟弱泥土を速やかに除去でき，さらに泥土を地盤材料に再資源化できたことは，災害現場での速やかな復旧に貢献できるものであり，社会的意義は大きいと考えている．
