The results of the development work on cementing hydrate-sludge pulp extracted from storage containers at the radiochemical plant of the Mining-Chemical Combine are presented. The work was performed on dummy wastes and real pulp under laboratory conditions as well as on an experimental cementing facility with a pulsation-type mixer developed at the Bochvar All-Russia Research Institute for Inorganic Materials. The properties determining the quality of the cement compound – mechanical strength under compression, water- and frost-resistance, leaching of 137Cs – as well as important technological characteristics, such as cement spreadability and heat release during hydration of the binder were determined for different matrix mixes differing by composition, water/binder ratio, degree of pulp inclusion and form of the binder and sorption additive.
