Use of ferro-concrete products as building materials at erection of buildings and construction is most demanded till present moment. It is caused by high degree of reliability and bearing ability of the given products which have been enough adjusted by the monitoring system behind manufacture. Thermomoist processing of concrete and ferro-concrete designs is an integral and responsible part of technological process of manufacture of a building complex of Russia. Power expenses for performance of this technological operation make more than 50 % from all power inputs of the enterprise. Application of infra-red radiation causes certain features in modeling of process of distribution of heat and, as consequence, warming up of concrete products in thickness. In the article modeling of process of distribution of heat and calculation of temperature and time of warming up in a concrete product with Ik-radiation use with reference to the chamber of infra-red heating is considered. It will allow to conduct scientifical works on optimization of constructive characteristics of Ik-installation, choice of Ik-radiators and their arrangements in the chamber. The physical model of experimental installation of a set of temperature of the investigated sample is presented at various ways of transfer of heat. During solvation of the problem of non-stationary heat conductivity the calcution of time of warming up of a concrete product in the chamber of thermomoist processings has been executed. On the basis of the received data the primary goals of experiments have been defined. They should include revealing of temperature field in the investigated sample with various sources of Ik-radiation, influence of length of a wave and duration of process of thermomoist processings on strength characteristics of received products.
