Simulation of the process of local destruction of concrete by high temperature gas jet containing a particles of condensed phase

A phenomenological model of concrete destruction process action of high temperature heterogeneous gas jet with high concentration of condensed phase particles has been proposed. Model based on generalized experimental data on temperature dependence of concrete strength and takes into account an abrasive effect of high temperature heterogeneous gas jet on concrete surface, the strength of which is decreased at temperature increasing. The results of numerical calculations show a reasonable agreement with experimental data.
