diameter ratio. This minimum occurs at approximately 20 to 30% of the smaller particle diameter. In real rocks we have a continuous spectrum of grain sizes, and these can give rise to a complex scenario, where fractal concepts become useful. Figure 2.4 Apparent volume for assemblages of spheres of different diameter ratios.

spheres. (Adapted from Hillel, 1980, Fundamentals of soil physics, Academic Press, p. 97.) Porosity is often conceptually partitioned into two components, most commonly called textural and structural porosity. The textural component is the value the porosity would have if the arrangement of the particles were

Porosity - Wikipedia

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and . Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell ).. There are many …
