Inclusion of Radioactive Ion-Exchange Resins in Inorganic Binders

Abstract

This article is devoted to the inclusion of ion exchange resins in portland, portland blast-furnace, and alumina cements. The degree to which the solidified products are filled with respect to dry resin reaches 7–10, 12, and 18.9–19.7%, respectively, with adequate strength being maintained (at least 5 MPa); the cesium diffusion coefficients are 9.3·10−4, 1.2·10−4, and 7.2·10−5 cm2/day with the normative value 6.7·10−4 cm2/day. When 10 mass% clay is added to alumina cement, the diffusion coefficient of cesium decreases to 5.1·10−6 cm2/day, and the volume of the wastes increases by not more than a factor of 1.5 on solidification.
