The results of a study of the composition and thermochemistry of transformations occurring in a heat-resistant coating on steel building structures are presented. It is noted that high performance properties - adhesion, compressive strength ensure high quality of the developed composite material planned for release in the form of a dry building mixture.
The use of thermodynamic calculations and modern research methods of thermo-graviometric analysis, micro-X-ray spectral, X-ray phase analysis and others made it possible to reliably establish the nature of thermochemical transformations in the hardening composition. A conclusion is made about the prospects of its production and use in construction practice.
