The paper studies the basic physical, mechanical and thermal properties of concrete with three types of supplementary materials for use in waste repositories. The used supplementary materials were natural zeolite, brick dust and metashale. These have pozzolanic properties which modify the parameters of resulting matrix and the unreacted part of the material offers sites for sorption of hazardous species. Results showed rather negative influence of natural zeolite on compressive strength and porosity, as well as thermal properties when compared to brick dust and metashale.
