Outline of Final Research Achievements |
This study focuses on mechanical properties of recovered soil generated through disaster waste treatment after the East Japan earthquake and tsunami. The main achievements obtained in this study are as follows: 1) Combustible ratio of recovered soil can be largely quantified by heating at 330-350 celcius for 48 hours, 2) although strength decreased with increase in wood content, some degree of residual strength can be expected due to skeleton structure by wood matters, 3) although specimen is absolutely compressed by decay of mixed wood matters, change in void ratio become relatively smaller under higher pressure.
