The investigation of the composite ceramic system containing easily fusible hydro-micous clay, technogenic finely dispersed raw material, and burning out waste additive is presented in the article. The properties of the raw materials used are described in the paper. The obtained ceramic bodies were burned at 1000 °C and 1050 °C temperatures, keeping at the highest burning temperature for 4 h. The analysis of physical-mechanical properties of composite ceramics (density, compressive strength, water absorption), its structural parameters (effective and total open porosity, reserve of pore volume, relative wall thickness of the pores and capillaries), and X-ray diffraction analysis was performed. The interdependencies between some structural parameters are described by empirical equations.
