Abstract

The paper sluge (PS) ash of Nippon Paper Industries co.,ltd. Yoshinaga Mill had been re-used only for cement, but we started the development of soil improvement material as other application of PS ash with Fujita co.,ltd.. The results are followings.<BR>1. The PS ash of Yoshinaga Mill is suitable for soil improvement material as it has excellent absorption capacity comparing with another product.<BR>2. The PS ash of Yoshinaga Mill doesn’t include harmful components except the elution of fluorine.<BR>3. The manufacturing of soil improvement materials could be realized by establishing the appropriate treatment to control the elution of fluorine.<BR>4. It is possible to control the elution of heavy metal and bad smell of mud.<BR>In this paper, we show the treatment method, fundamental properties of the improvement materials and report the results of application to some actual construction fields (dredging harbors and rivers and improving the illegal dumping spot). At present we examine the application for debris classification of the 2011 Off the Great East Japan Earthquake.
