Annotation: In this paper, the thermomechanical properties are studied, the compositions of slag-alkali binders based on ground coal slag of the Zuevskaya TPP are optimized in order to use them for heavy alkaline heat-resistant concretes. The influence of the silicate modulus, as well as the influence of the density of low-modulus liquid glass (Ms = 2,0) on the activity of slag-alkali binders, was revealed. The change in the physical and mechanical properties of the stone of slag-alkali binders at ordinary temperature, after drying and firing at a temperature of 1 000 °С was studied. It has been established that slag-alkaline binders based on ground coal slag from the Zuevskaya TPP have increased heat-resistant properties. Thus, the possibility and expediency of using ground coal slag in the manufacture of alkaline heat-resistant concretes has been proved. Also, alternative slag-alkali binders make it possible to increase the raw material base for the preparation of heat-resistant concretes and reduce the environmental damage caused by the production of cement.
Keywords: slag-alkali binder, heat-resistant concrete, linear shrinkage, strength, slag TPP, weight loss.
