Study on subjects and applicability for mud improvement due to mixing with paper sludge ash

Abstract

Paper sludge (PS) ash is cinder that is generated when paper sludge (waste of paper manufacturing) is incinerated. We have previously studied application of PS ash in the construction field(improvement of excavated mud etc.)and found that PS Ash had high swelling ability and can be used for environmental clarification of mud. We developed a new soil improvement method and design. However, in late years it comes to be recognized that the improving effect becomes bigger than early stage having curing function and the coverage of PS Ash product spreads out because the property of PS ash changes and some product is manufactured using different PS ash by different processing.In this paper, I examine the improvement function of the present PS ash materials and report the applicability of new PS ash improvement.
