摘要：

The results of investigations of the porosity of heat-efficient ceramic materials based on clays with different mineralogical composition with a porous glass component (PGC) and their impact on the frost resistance and thermal conductivity are reported. It was found that the content of the illite and montmorillonite subgroup of clay minerals in compositions with PGC determines the optimal quantitative ratio of meso-, macro-, and also 'dangerous', reserve, and 'safe' pores, which promotes high frost resistance and reduction of the thermal conductivity of the materials.
