The cation-exchange and cesium-sorption properties of hydrated cements with and without pozzolans were determined. Compositionally adjusted (silica fume added) hydrated cements exhibit substantial cation-exchange capacity. For example, portland cement type II/I with 30% silica fume (hydrated at 60 degree C for 6 weeks) has an exchange capacity of 44 meq/100 g. These hydrated cements have Cs sorption capability, but this sorption is not specific. The cation-exchange and cesium-sorption properties of hydrated cements may be important in nuclear and hazardous waste disposal.
