THE MOISTURE REGIME OF ENCLOSING STRUCTURES IN DIFFERENT CONSTRUCTION AREAS

Abstract

Heat and mass transfer mathematical model is formulated. Solution of the moisture transfer equation was obtained by discrete-continuum approach, which gives an opportunity to obtain the new analytical solution. Algorithm for calculating the moisture regime according to the proposed mathematical model is given. Enclosing structure with aerated concrete base and expanded polystyrene insulation is chosen for moisture regime calculation. Moisture behaviour calculation is done in three construction areas (dry, normal, wet) for four different moisture regimes of building room (dry, normal, moist, wet). Calculation results were summarized in a table which engineers can use in their practical work
