Incorporation of spent tributyl phosphate inTO cement matrix using thermally expanded graphite

Cement compounds containing up to 20% (volume) of tributyl phosphate in hydrocarbon are synthesized. Leaching of cesium-137 from them has been studied. It is shown that coating of the compounds with enamel based on chlorinated rubber prevents water penetrating into the cement matrix and delays the start of leaching. Satisfactory leaching rate is observed for the compounds containing not less than 6% (mass) of bentonite.
