Abstract
The invention relates to a process for the conditioning of radioactive or toxic waste in epoxy resins and a polymerizable mixture with two liquid constituents usable in this process. This process consists of incorporating the waste into a polymerizable mixture incorporating at least one epoxy resin, pitch and at least one epoxy resin hardener and allowing the thus obtained mixture to harden. Generally the mixture comprises at least 50% by pitch weight and can be used for treating radioactive waste constituted by large objects and organic liquids.
