CONCRETE AND REINFORCED CONCRETE IN THE CONDITSONS OF HIGH TEMPERATURES AND FIRE

Abstract

The methodology of complex investigations of behaviour of concrete under the influense of high temperatures in the conditions of “standart fire” with the active protection by the inflating coverings of the base composition and the improvement applying to the fire protection of the concrete and reinforced concrete constructions is researched in the article.

The investigations are conducted on the examples of the concrete of two kinds: on the heavy and light keramzit concrete, protected and unprotected by the inflating coverings.
