AbstractA non limitative method is discussed to evaluate the open porosity of air-saturated porous materials. The proposed method deduces the open porosity through the experimental determination of the volume of the solid phase of a porous aggregate. The proposed missing mass method time efficient and does not assume isothermal conditions for the test. The results show that the last three meters can be eliminated if the ambient air density is measured using the missing mass as per the first test.
