Publikováno v: Workshop on waste cement hydration
Workshop on waste cement hydration, 2008, Nantes, France
Cementation is a widely applied technique for the conditioning of low- and intermediate-level radioactive wastes. In particular, the use of cement is an attractive procedure to immobilize evaporator concentrates from aqueous effluents treatment. This
