Sized (classified) are the materials for which the ratio between the size of the largest lump/particle, a max and smallest lump, a min is less than or equal to 2.5. Unsized (non-classified) are the materials for which ratio a max / a min is greater than 2.5. Average lump size of a sized material = (maximum particle size + minimum particle size) / 2
