Measurement of thermal, hygric and physical properties of bricks and mortar common for the Polish market
Abstract
Hygric, thermal and physical properties were determined for building materials typical for the Polish market. One type of mortar and two types of masonry bricks were studied. Thermal diffusivity and specific heat of dry materials were found using the flash and differential scanning calorimetry methods, respectively. Water vapour permeability was tested using the cup method for a single temperature of 23°C and for two ranges of the air relative humidity (from 0 to 50% and from 50 to 94%). The permeability tests were performed according to ISO 12572:2016. Measurements of the sorption isotherms were carried out using the environmental chamber method, according to ISO 12571:2013. The results of measurements of the apparent and true density of the considered materials were used to determine their porosity. The presented measurements concerned materials involved in physical and numerical experiments aimed at quantitative and qualitative analyses of heat and moisture transfer during drying of building materials and walls.
