The article presents various methods of synthesizing heat-resistant binders based on large-tonnage wastes of the ceramic industry. The use of expanded clay dust in the compositions of heat-resistant concrete on portlandcement allowed to increase their residual strength in the zone of critical temperatures (800-1000 ° C). It was revealed and justifi ed that the use of phosphate binders for synthesizing a binder made it possible to increase the refractoriness of the heat-resistant composition based on expanded clay dust to 1300-1350 с. As the experiments show, claydite dust in its composition contains a clay component, which ensures the plasticity of the ramming mass. It was established that samples of ramming mass on orthophosphoric acid did not require heat treatment and can be immediately removed.
