Determination of real density and apparent density, and of total and open porosity. The specimens have been dried at constant mass, weighted (m d ), cooled down in a desiccator, put under vacuum for 1 day, introduced water under vacuum and let them there for 1 day, stop the vacuum and let them under water at atmospheric pressure for 1 day. Then the specimens have been weighted in water (m h ) and in air (m s ). The apparent density has been calculated as: ρ rh *m d /(m s -m h ) in which ρ rh is the density of water at 20ºC =998 kg/m 3.
