Abstract
The handling and disposal strategies of coal combustion residuals (CCRs) such as fly ash, bottom ash, and gypsum in the US are undergoing a paradigm shift from wet sloughing in a basin to dry disposal in an engineered landfill. This shift is motivated in part due to recently implemented regulations by the U.S. Environmental Protection Agency. As part of these new approaches of handling and disposal it will be important to investigate compaction characteristics as well as water infiltration behavior of CCRs. This paper presents results of an ongoing study where 7 different CCRs materials from different utilities in the US have been characterized. Specifically, the paper presents geotechnical index properties, compaction curves, X-ray fluorescence, X- ray diffraction, and water retention characteristics of compacted CCRs samples. Also discussed is the relevance of these results towards alternative capping systems that would involve compacted CCRs materials treated with organosilane chemicals to render the cap essentially hydrophobic.
