Corundum composition heat insulating materials are used successfully for high-temperature insulation and are mainly produced by casting that has a number of disadvantages. The authors of the present article propose a vibration-compaction method for producing such materials that makes it possible to intensify the production process. Results are provided for a study of the compositions for preparing corundum heat-insulation materials based on hydraulic binders. The main features are established for the effect of charge component content on specimen physicomechanical properties. Optimum compositions are revealed satisfying the specifications of GOST 5040–2015.
