Abstract
The article presents various methods of heat-resistant materials synthesis on the basis of aluminosilicate wastes of expanded clay production. Researches have shown that the application of physical and chemical methods in the course of studying of expanded claydite dust composition, structure and properties makes it possible to define the reason of physical and thermal parameters increase of the heat-resistant binders prepared in its composition. The article investigates the influence of refractory mineral waste of petrochemistry - aluminochromium spent catalyst IM-2201 on the processes of increasing the strength and performance indicators of binders based on expanded clay dust. The possibility of the fire resistance increase of mixed binders synthesized on the basis of expanded claydite dust and aluminochromium waste has been established. Application of phosphate and liquid glass binders in the processes of heat-resistant binders synthesis on the basis of expanded claydite dust allowed to increase their performance.
