A Contribution to the Analysis of Water Vapor Transport in Porous Building Materials

Abstract

The suitability of a water vapor transport parameter determined by the cup method for the description of water vapor transport in porous building material is analyzed in the paper. The relative humidity profiles are measured by a transient method with different water vapor pressure gradients. Moisture profiles calculated using a mathematical model are compared with the measured profiles. The goodness-of-fit tests are calculated for different experimental setups. The possibility of application of the analyzed water vapor transport parameter is discussed.
