Details

The present study is structured according to thematic point of views. Emphasis was laid on a precise description of the behaviour of cement used for the solidification of radioactive waste. By utilizing different additives, processing as well as properties like leaching mechanical strength etc. can be improved. In the same way these properties can be positively influenced by various solidification processes and hardening conditions. Chapter 4 discusses the most common kinds of wastes (ion exchange resins, concentrates, solutions etc.). Cement additives and mixtures as well as processing have to be adapted according to the kind of waste to be solidified. In the last chapter activities in different countries in the field of cementation of radioactive wastes are reviewed.
