Abstract
The main aim of this work was to investigate the effect of temperature on the capillary water absorption coefficient. Different categories of building materials such as stones, bricks and mortars of various compositions, for three different levels of air temperature (20, 25 and 30 °C) were studied. A linear dependence of the capillary water absorption coefficient with temperature was found for all examined materials, however with different slope values for each material. In order to assess the validity of the linear dependence of the capillary water absorption coefficient on the temperature, capillary rise experiments were performed at the temperature of 15 °C and a very good agreement between experimental and predicted values of the Aw was obtained. Finally, other models correlating the capillary water absorption coefficient Aw with temperature suggested by other researchers were evaluated.
