Immobilization of ion-exchange resins in cement
The removal of radioactivity from spent decontaminating solutions, e.g. LOMI, can be achieved using organic ion-exchange resins. These resins can be immobilised successfully in cement-based matrices. The optimum cement system contains 10% ordinary Portland cement, 84% gg blast furnace slag, 6% microsilica with a water/cement ratio of 0.5 and a dry resin loading of 36% with respect to total weight. This formulation has been successfully scaled up to 200 litres, giving a product with acceptable compressive strength, dimensional stability and elastic modulus. Storage of samples under water appears to have no detrimental effects on the product's properties.
