Properties of artificial lightweight aggregates(ALAs) made of dredged soil mixed with waste catalyst slag Sinae Jo1, a, Yootack Kim1,b, Seunggu Kang1,c and Changsam Kim2,d 1Department of Advanced Materials Engineering, Kyonggi University, Suwon, Korea 2Energy Storage Research Center, KIST, Seoul, KOREA atlso1535@naver.com, bytkim@kgu.ac.kr, csgkang@kgu.ac.kr, dcskim@kist.re.kr Keywords: artificial light-weight aggregates, dredged soil, waste catalyst slag, bloating, black core Abstract.
The ALAs fabricated in this study showed the specific gravity of 0.8~2.0 and water absorption of 2~16% so it could be applied to various fields such as the lightweight concrete for civil Structures or the field of the porous carriers for purification of a contaminated soil or water.
