Abstract
The purpose of the study is to examine the morophology, physical structure, and metal compositions of leached cement-based waste form by using various testing procedures. In the study, a series of leach tests were conducted in the laboratory. After the sample had been leached for a given period of time, the leached surface layer was physically separated from the remaining portion of the cement-based waste form. The metal contents of the surface layer and the remaining unleached waste form were examined individually. The data generated from this research will be useful to the understanding of the fate and transport of metal contaminants leaching out of solidification/stabilization waste forms. In addition, the metal distribution information could be useful in the determination of appropriate model(s) used to predict metal leaching behavior.
