Assessment of Stress-Deformed State of Armocement Two-Layer Elements

One of the main causes of death of people and damage from the fires is the collapse of building constructions. Efficiently increases in limit of fire resistance of building constructions drawing heat-protective coverings is. As expanded aggregates for such coverings, bellied vermiculite and perlite are used. Along with the main function of fire protection, they can improve acoustic, decorative, heatphysical characteristics of designs that increases efficiency of their application.
