Abstract
With the help of a previously developed technique based on the
solution of inverse and direct problems of heat conductivity, the fire
resistance of a hollow-core reinforced concrete floor with “Neosprei” fire-
retardant plaster coating was estimated. The thermal and physical
characteristics, as well as characteristics of the fire-proof ability of
“Neosprei” fire-retardant plaster coating, have been determined. The
conclusion has been made on the effectiveness of this coating and on the
boundaries of the fire-retardant coatings use to ensure the normed values of
the fire resistance degree of hollow-core reinforced concrete floors,
including in the mining industry.
