Abstract
New cement compositions for solidifying mixtures of spent ion-exchange resins in sodium, nitrate, and tetraboric-acid form were developed. Depending on the composition of the cement and the ionic form of the anionite, the proposed cements make it possible to incorporate into the matrix 22–83 wt.% more ionexchange resins compared with using conventional portland cement. The matrices with heightened content of ion-exchange resins meet the requirements of cemented radioactive waste in terms of strength, water resistance, and leaching of 137Cs.
