How to Calculate Void Ratio

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 …

Crushed Stone Calculator

Here's how you can use the crushed stone calculator: Select your surface shape, e.g., Rectangular.. In surface length, enter the length of your surface, e.g., 12 feet.. In surface width, enter the width of your surface, e.g., 8 feet.. Now, enter in depth, how deep do you want to fill the layout of your surface, e.g., 3 inches.. The waste factor tells how much …

Effects of particle size on compressive deformation …

The void ratio of different particle sizes decreases exponentially with the increase of load grade during the compression process. The rate of void ratio change increases with increasing particle size and reaches a similar value at 1.4 MPa load. The crushing ratio of the compressed crushed stones increases with increasing particle size.

Void Ratio and Shear Strength of Two Compacted …

At the minimum void ratio point, the rate of volume change within the sample is zero and no corrections are necessary due to this effect. ... crushed stone is a function of the void ratio, since as stated in the previous section, the shear stress-void ratio function is parallel to the consolidation pressure-void ratio function. Therefore, the ...

Examining Stone Void Space Part 1: Is 40% a Reliable Number?

Depending on the underground structure design and size, allocated storage within the stone voids can vary between 25-60% of the overall storage for the project. The generally accepted number has been 40% stone void space. However, there have been few national studies to prove the 40% void space is reliable.
