Summary

The real density of a porous matter is determined by means of the equationV=a − b · s, whereV is the volume of imbibition, related to the surface tension (s) of the liquid, while “a” and “b” are experimental coefficients. The examination of this equation led to the conclusion that “a” represents the total porous volume, while “b” is a function of the mean porous radius. The knowledge of the equation related to a given substance, allows to calculate immediately the real density.

Furthermore the ratiob/a defines a characteristics porosity index.
