[III-506] Study on ground improvement with paper sludge ash
Keywords:Paper sludge ash, heavy metal, insolubilization, ettringite, ground improvemet
The paper sludge ash generated from pulp and paper factory contains 40-50% of CaO, it was expected as ground improvement materials superior in economy.
In this research, authors investigated ettringite formed is extremely effective for insolubilization of heavy metal (fluorine) in paper sludge. Secondly we decide mixture of ground improvement by the results of ettringite formed, and investigated the effect in laboratory test.
