Abstract
Random packings of grains of arbitrary shape are built with an algorithm that is mostly applied to spheres, ellipsoids, cylinders, and parallelepipeds. A systematic account of the main geometrical properties such as the porosity, the reduced specific area, etc. is given. The conductivity, the permeability, and the dispersion are also systematically determined and they are shown not to depend upon their mode of construction.
