This article discusses the fire resistance problems of building structures, their criteria for use, the temporal limits of the spread of fire in buildings and building structures, and their classification. A calculation method is proposed for determining the properties of heat-resistant concrete and building materials, the grouping of building materials by fire resistance, the level of fire resistance of buildings and structures, as well as the determination of the fire-resistant properties of buildings by a fire test. The question of the use of heat-resistant heavy concrete with their properties is considered.
