Proposed investigate variety heat treatment of concrete and reinforced concrete products using only the heat released during cement hydration. The peculiarity of this variety consists in that the surface of products not hydro-insulated. Accordingly, in the thermal chamber than heat exchange processes the processes of mass transfer between the surface products and the air chamber. In the quantitative analysis of these processes is necessary to know number the initial factors, among them - the moisture content of the air chamber. The processes of heat and mass transfer between the surface of concrete and reinforced concrete products and air chambers begin already during loading them into the camera. During the loading of products is air combined with air workshop. Therefore for each case must quantify the impact of mass transfer processes on the initial moisture content of the air chamber. Considered dependence that characterizes the process of evaporation of moisture from the surface of concrete products. Results of calculating the amount of moisture that evaporates from the surface of concrete paving slabs during selected period of time. In further research is necessary to analyze the processes of heat and mass transfer in the chamber, where the heat treatment of concrete or reinforced concrete products (non-hydro-insulated) is using only the heat released during cement hydration.
