Learm More### what is the void ratio of gravel? | Yahoo Answers

09.06.2010· It is the ratio of Void Volume / Total Volume of gravel. It can be calculated by taking the gravel in a known volume (a cubic box for example). After filling the box level with gravel, start adding water gradually using a graduated jar and stop when the box becomes full and the water starts just overflowing. The volume of the water added represents the voids in the gravel and that divided by ...

The void ratio (e) is the ratio of the volume of voids (V v) to the volume of solids (V s). Porosity (n), on the other hand, is the ratio of the volume of voids (V v) to the total volume (V) or volume of the voids plus the volume of the solids (V v +V s). The void content formula or void ratio formula would be written as e=V v ÷V s while the porosity formula would be written as n=V v ÷V. The ...
