The compressive strength of the simulated waste form

The radioactive wastes after treatment must be kept in a suitable waste form for further storage and/or ultimate disposal. Cementation is one of the suitable methods for conditioning of such waste because of its simple, cheap and good quality of products. The basic properties of radioactive waste form particular significance regarding an evaluation of performance in the disposal environment include: leachability, radiation resistance, thermal properties and other mechanical properties, especially the compressive strength. In this study, the compressive strength of conditioned waste products of various simulated waste compositions are tested. As according to the recommendation for safe handling during transportation and disposal of cemented radioactive wastes, the minimum compressive strength requirement is 150 kg/cm3. The proper percentage compositions of the cemented wastes founded in this work are 12.18-15.25, 20.77 and 19.05-54.14 for the spent resin, sludge and inorganic absorbers respectively
