Abstract
Recently, sludge purification of organic matter enriched sediments using granulated coal ash(GCA) have been used in Hiroshima delta areas. It has been proved that GCA can absorb the compounds of phosphorus, nitrogen and sulfur. However, the material properties of GCA for soil reactivity and sediment stabilization have not been clarified. The purpose of this study is to evaluate the sediment stabilization mechanism and the performance of sediments improvement by GCA utilized as covering material. Laboratory experiments were carried out to evaluate the soil reactivity (e.g. chemical properties, CEC, phosphate absorption coefficient) and sediments stabilization mechanism by GCA covering method. And, field investigations were also carried out to estimate the stabilization ability by GCA. From our findings, it is concluded that GCA can be used as a covering material to improve sediments stabilization in organic matter enriched sediments.
