The main aim of this paper is determined of properties, especially granulometry, of recycled silicon carbide waste and its possibility of using in new cementitious recipes. Paper is focused on importance of creation of grain curves and on relationship between silicon carbide and compounds in concrete matrix. Purpose of this research is using waste material and therefore minimalizes of its production and reduces ecological effect on environment by its recycling. Set of granulometry measurements of each recycled materials were done as well as its grain characteristic. The End of work includes the evaluation of the possible use of SiC waste for cement mixtures.
