The article presents three original methods to determine the pore volume distribution as a function of radius. The simplest method consists in the use of one - dimensional model of building material porosity structure. The method can be used if evidence is not available. The second method is based on the cylindrical model of porosity structure. The method can also be used if evidence is not available. The last, most complicated and most accurate method to determine a pore volume distribution as a function of radius consists in the use of kinetics evidence of capillary rise.
