Abstract
A process for solidifying radioactive wastes, which comprises adding, to pellet or dissolved radioactive wastes, an alkali metal silicate as a filler, silicic acid, carbonic acid or an alkaline earth metal or polyvalent metal salt thereof as a hardener, and cement as an absorbent for absorbing water to be released with the progress of the reaction and, if necessary, water and mixing and solidifying the resulting mixture to thereby prevent deterioration of water-proofness due to precipitation of readily soluble salts on the surface of a solidified substance.
