Evaluation of the mechanical behavior of the matrix of the radioactive waste containment according to the physical and chemical state of organic and inorganic macromolecular binders

New formulations of the containment matrix of Ion Exchange Resin (IER) were studied depending on the physical and chemical state of the inorganic and organic macromolecular binder. The prepared formulations containing a macromolecular organic binder polyepoxide in its powder state (grain size = 0, 40 µm) and the inorganic solid macromolecular binder (zeolite 4A) is characterized by the improvement of the compressive strength as mechanical properties. The obtained improvement is synonymous with the good dispersion of fine particles of both the inorganic and organic macromolecular binder in the IER containment matrix.
