Dec 16 2013 the void ratio is the ratio of the volume of voids open spaces ie air and water in a soil to volume of solids where e void ratio v v volume of voids m 3 or ft 3 v s volume of solids m 3 or ft 3 v g volume of air m 3 or ft 3 v w volume of water m 3 or ft 3 the void ratio is thus a ratio which can be greater than 1 it can also be expressed as a
Jan 05 2009 i suspect you mean 40 voids which is the maximum value that can generally be obtained by using clean uniform angular stone the void ratio is the ratio of voids to solids so 40 voids would correspond to a ratio of 4060 23 peter smart hydrocad software
Jul 01 2008 bear in mind coarser soils have a lower void ratio than finer soils so just because you can see the voids of a large aggregate material does not mean the void ratio is greater than a fine grained soil given a void ratio of 03 and a specific gravity of 27 the dry density would be gammad0762427118
