Relationship of void ration to rock size/shap - Soil ...

05-01-2009  On the subject of void ratio, if you have one size spheres, the maximum void ratio you can get is 0.92 with them stacked one on top of the other, as loose as possible. When they are nested as close together as possible, the void ratio is 0.35.

Void Ratio for Common Gravel Sand Sciencing

In soil mechanics, the void ratio describes the relationship between the volume of voids, or spaces, in the soil or aggregate to the volume of solid constituents, or grains. Algebraically, e = Vv /Vs, where e represents the void ratio, Vv represents the volume of voids and Vs represent the volume of solid grains.

Determination of Minimum Void Ratio of Crushed

This experimental investigation aims at developing a reliable method for the determination of the minimum void ratio (e min) of crushed rock sand using a vibrating table test. The minimum void ratios of one natural sand (Toyoura sand) and five commercially available crushed sands were measured using both vibrating table and pluviation tests.

Void Ratio of Noncohesive Soils and Similar

A new approach to the topic of numerical description of void characteristics of noncohesive soils and similar granular materials is presented. Based upon a simple stochastic model of the void structure and void sizes, theoretical equations are derived by means of which the void ratio of a soil can be calculated from its grain‐size distribution.

How to Calculate Void Ratio - ProjectEngineer

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.

As we already discussed, crushed stone is simply natural rock that is crushed by machinery and then sorted and screened into different groups depending on size and components. This crushing and screening process is typically done at quarries. Depending on the rock available at a construction site, crushers are hauled directly to the site for use.

Void ratio - Wikipedia

The void ratio of a mixture is the ratio of the volume of voids to volume of solids. It is a dimensionless quantity in materials science , and is closely related to porosity as follows: e = V V V S = V V V T − V V = ϕ 1 − ϕ {\displaystyle e={\frac {V_{V}}{V_{S}}}={\frac {V_{V}}{V_{T}-V_{V}}}={\frac {\phi }{1-\phi }}}

Void ratio - geotechdatafo

Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.
