Abstract
Solid, leach-resistant bodies are formed from aqueous heavy metal sludge and fly ash formed in the combustion of subbituminous coal from the Power River Basin by slurrying the sludge with an amount of fly ash equivalent to between about 20 wt. % and about 70 wt. % based on the weight of the slurry, wherein the initial liquid content of the slurry is such that the slurry will harden into a body having a 7-day compressive strength of at least about 250 psi, and allowing the slurry to harden.
