ON THE EFFECTS OF PS ASHES STABILIZING MATERIAL ON THE DREDGED MUD

Abstract

 PS (Paper Sludge) ashes are discharged from paper mills and becomes popular in not only absorbing technology but also environmental purification. In this study, the strength of the dredged mud improved by PS ash stabilizing materials are investigated for the purpose of utilizing it for marine neighboring facilities. As PS ash improved materials have high φ' and c' and can secure predetermined degree of compaction within wide range of water contents. Utilization is enabled around ocean facilities even though the dredging mud was unsuitable for ground reclaimed and the backfill for marine facilities.
