REUSE OF POND SEDIMENT BY MIXING WITH STABILIZERS AND SHREDDED PAPER
Hyogo Prefecture has many irrigation ponds. Sediment in the ponds is removed during agricultural offseason. Because pond sediment has high water content, it is usually stabilized with stabilizers such as cement and lime. Stabilized soil has brittle shear behavior therefore it is quite different from natural soils. The fiber reinforced soil was able to improve the mechanical properties of soft soil. To improve brittle shear behavior of stabilized soils, the authors carried out a series of mixing test of soft clays with cement and shredded paper as a fiber. And unconfined compression tests of cement stabilized clays mixed with shredded paper were performed. As the result, by mixing with shredded paper, the unconfined compression strength of cement stabilized clays increases and the shear deformation behavior is improved.
