ABSTRACT:
The solids content of aqueous coal sludge slurries such as coal washings are stabilized in a hardened state by concentrating the solids content thereof, adding to the concentrated coal sludge 2-50% by weight of the solids of granulated blast furnace slag, with intimate mixing, and maintaining the mixture in a quiescent state and in the presence of excess water to produce a sedentary mass having load supportive properties suitable as landfill.
