ABSTRACT:
A solidified waste is formed from a difficult-to-compact hydraulic cement slurry for use in the disposal of hazardous waste. The slurry contains inorganic non-compactible hydraulic cement particles, a concrete superplasticizer compound, water, and filler particles containing radionuclide and/or toxic contaminants. The slurry is then transferred to a storage vessel, such as a subterranean formation, to cast a stronger, denser solidified waste than a comparable solidified waste containing no superplasticizer.
