Abstract
This paper examined the utilization of bamboo that has been cut down in order to solve the standing problem of bamboo forest. Focusing on water absorptivity of bamboo chips and flakes, we consider improving the high water content soft clay such as dredged bottom mad. As a result, we found that there is sufficient improvement effect on bamboo chips and flakes. Improving effect would be affected by the differences in the absorption properties of bamboo chip and flake. In addition, the combination with solidification material, it is effective to reduce the solidification material addition rate. And, the addition of solidifying material is found also affects the decay of bamboo in improved soil.
