A study of leaching tests for cement stabilised waste
2002
Beard, Jason
A cement-stabilised waste was subjected to batch, column, and dynamic leaching tests, and the leaching behaviour of arsenic, copper, lead, selenium, and zinc was investigated. Batch tests included the Australian Bottle Leaching Procedure (ABLP, AS 4493.3-1997), Toxicity Characteristic Leaching Procedure (TCLP, USEPA Method 1310); column testing included small columns (internal diameter = 24mm) and a large column (internal diameter = 500mm); and dynamic leaching tests were run with both short (1 hour) and long (4 hour) leachant renewal frequencies. A maximum availability test was used to indicate maximum leaching potential for the metals under investigation.
