The set of 25 inorganic porous building materials was put through the cumulative water inflow and drying tests in laboratory conditions. Besides these experiments the parameters, including pore structure parameters of the tested materials have been determined. The characteristics of the capillary suction induced water absorption – the water absorption coefficient, and drying – the initial constant drying rate, were compared with their analytical expressions. The results of this analysis show the measure of particular material parameters and boundary conditions significance for the coincidence of experimental and calculation results. At the drying an important correlation between experimentally obtained initial water content and drying rate was observed.
