  • The Complete Guide to Crushed Stone and Gravel

    Nov 11, 2019· Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water. Unlike crushed stone, gravel is usually sold and used in its natural state.

  • How to Calculate Void Ratio - ProjectEngineer

    Dec 16, 2013· The void ratio is the ratio of the volume of voids (open spaces, i.e. 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 fraction.
