The greater the void space in a rock or soil, the lower the overall density of the material. Finding the void calculation for soils uses basic tools and a little math. Measuring the specific gravity and the dry density lets the total volume, void ratio and porosity be calculated
2018-12-19where e g100 is the global void ratio at an effective stress of 100 kPa and e L is the void ratio at the liquid limit.

Soil porosity n is the ratio of the volume of voids to the total volume of the soil n Vv V. Where Vv is the volume of the voids empty or filled with fluid, and V is the total volume of the soil. Porosity is usually used in parallel with soil void ratio e, which is defined as the ratio
2020-5-21and reduce the void ratio. 3.1 Purpose of Compaction The principal reason for compacting soil is to reduce subsequent settlement under working loads. Compaction increases the shear strength of the soil. Compaction reduces the voids ratio making it more difficult for water to flow through soil
The void ratio and dry unit weight can then be derived from equations 3 and 5, respectively. The porosity n can subsequently be estimated with the following relationship 8 The method is summarised in three steps in Figure 1. Figure 1 Summary of proposed methodology for sands estimating w, e, d and n. 2.2 Advantages of the proposed method

2015-9-13Minimum void ratio or maximum packing density is an important soil property in geotechnical engineering. It correlates to the volumechange tendency, the pore uid conductivity,and the shearstrength of thesoil. In geo-technical engineering, it often requires to estimate the minimum void ratio for a sandsilt mixture with any
2014-5-27It is found that intergranular void ratio can predict stress-strain response of sand with low fines content say 10 only. To extend the applicability of intergranular void ratio to higher fines content, an additional parameter b has been in-troduced by some researchers in the calculation of intergranular void ratio
Void Ratio of Noncohesive Soils and Similar Materials B. berg. Download ... Results of numerous laboratory compaction tests on uniform to broadly graded sand, gravel, and crushedrock materials confirm the general forms of the derived equations and are the basis for evaluation of certain parameters. In a companion paper, the theory is
Soil void ratio. 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 interrelated as follows e n 1n and n e 1e The value of void ratio depends on the consistence and packing of the soil.

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
The void ratio measured by conventional methods invariably includes some of the internal void space, and is therefore, not a true measure of void ratio in terms of the normal definition or understanding of the term. This paper examines different ways of measuring the specific gravity, and the influence of particle sie on the results
