Abstract
It is established that between the characteristic temperatures Tt and Tb the temperature-time dependence of the adhesive bond strength of adhesives and compounds with granite, concrete and steels is described by the Zhurkov equation. At T<Tt the strength does not depend on temperature, the time dependence of the strength is described by the quantum analog of the Zhurkov equation. An empirical expression describing the temperature-time dependence of strength at T>Tb is found. These results allowed us to propose a method for predicting the durability of adhesive bonds at any temperature based on the results of strength measurements in the interval Tt<T<Table.
