Title: EXPERIMENTAL STUDY OF LEACHING OF FLY ASH
Accession Number: 00713581
Record Type: Component
Availability: Find a library where document is available Abstract: Leaching of Alaskan coal fly ash was investigated to characterize the leachate generated and identify any toxic elements released in large amounts. Pressure was used to increase the rate of leaching in the column apparatus. Effects of compaction, freezing and thawing, curing, and cement stabilization on leaching were also investigated. Results indicate that high levels of barium are released from ash when rapidly leached with distilled water, although the Environmental Protection Agency Toxicity Characteristic Leaching Procedure test method did not identify this potential hazard. Stabilization of fly ash with portland cement reduces to the maximum concentration of barium leached.
