We should be careful here with terminology: "Voids" or "porosity" refers to the fraction of the overall stone volume that is empty space, and is often expressed as a percentage such as 25%. "Void ratio" is the ratio of voids to solids, so 25% porosity would be a void ratio of 25:75 or 1:3. Peter Smart HydroCAD Software
