A method of encapsulating hazardous waste materials including heavy metals such as arsenic, mercury, nickel and chromium residues, as well as radioactive materials. The method involves adding the hazardous waste material to a settable composition, forming a slurry, and allowing the slurry to set to encapsulate the waste material. The settable composition is a powdered flowable cement composition containing calcium carbonate and a caustic magnesium oxide. Tests conducted on the encapsulated material indicate that virtually none of the hazardous waste material is leached out of the set composition which has a concrete-like appearance.

L'invention concerne un procédé d'encapsulation de déchets dangereux renfermant des métaux lourds, tels que des résidus d'arsenic, de mercure, de nickel et de chrome, ainsi que des matières radioactives. Le procédé consiste à ajouter le déchet dangereux à une composition durcissable, à former une suspension, et à laisser durcir la suspension afin d'encapsuler le déchet. La composition durcissable est une composition de ciment fluide, en poudre contenant du carbonate de calcium et un oxyde caustique de magnésium. Des tests réalisés sur les déchets encapsulés indiquent que pratiquement aucun déchet dangereux n'est lixivié hors de la composition durcie présentant un aspect semblable au béton.
