We classify three types of natural sand (i.e., DS, NS, and FS) into five particle groups: 0.1 to 0.25 mm, 0.25 to 0.5 mm, 0.5 to 1 mm, 1 to 2 mm, and 2 to 5 mm particle groups. Among them, the number of particles of 2 to 5 mm in FS is very small, which is difficult to obtain.

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 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are many ways to test porosity in a ...
