ANALYSIS OF PHYSICAL PROPERTIES OF AIR AND WATER VAPOR FROM THE VIEWPOINT OF MATHEMATICAL MODELLING OF HEAT-HUMIDITY TREATMENT PROCESSES OF CONCRETE PRODUCTS

<p><em>The problem of mathematical modeling of heat exchange during the stage of heat-humidity treatment of concrete products is discussed. It is shown, the full set of equations for calculation of air and water vapor parameters, including their humidity and temperature dependencies must be taken into account in order to sinthesize the sufficient mathematical model. It is established that in practical calculations it is important to take into account the heat transfer as a convection, and a radiation from the vapor environment to the product surface. </em>
