Heat-Insulating Properties of Refractory Materials Made with the Use of Artificial Ceramic Binders

Resumo

It is shown that it possible to produce heat-insulating and heat-insulating/structural refractories based on artificial ceramic binders made from thermally activated refractory clays of different compositions. The slag-alkali binder used in the new materials undergoes strengthening by a unique mechanism. An analysis is made of the granulometric composition of the slag after comminution for different lengths of time and its main granulometric characteristics are determined. The main properties and microstructure of the new heat-insulating materials are studied.
