Summary:Cement matrices are being assessed for immobilization of radioactive wastes. Mineralogical aspects of cement chemistry and the uses of siliceous minerals as selective sorbants to enhance immobilization potential are discussed. Studies of sorption and leaching of cesium from pulverized fuel ash (PFA), blast furnace slag, tobermorite, xenolite, and clinoptilolite are reported. The role of incorporation of these additives in cement and the effect on the nature of the composite matrix on cesium behaviour has been investigated. Slags, PFA, and clinoptilolite undergo reaction at different rates. Tobermorite and xenolite appear to be stable in cement.—Modified jornal abstract. [R.A.H.]
