## How is void ratio calculated?

Void Ratio and Porosity Difference The void ratio (e) is the ratio of the volume of voids (Vv) to the volume of solids (Vs). The void content formula or void ratio formula would be written as e=Vv÷Vs while the porosity formula would be written as n=Vv÷V.

## How do you calculate the void aggregate ratio?

To calculate the void ratio we must first calculate the volume of solids. Then we can find the volume of voids by subtracting the volume of solids from the total volume.

## What is meant by void ratio?

The void ratio of a mixture is the ratio of the volume of voids to volume of solids.

## Can you have a void ratio greater than 1?

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. The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction. Void ratio and porosity differ only in the denominator.

## Which soil has maximum void ratio?

The void ratio of a dense sandy gravel soil is about 0.3, that of a loose sand is about 0.6, while the void ratio of clays (in natural conditions) varies between 0.5 and 1.0 and decreases with depth of the soil layers.

## What is Voidage and how is it calculated?

The term voidage is normally used to refer to the tiny spaces between particles in a powder or granulated material like sand. The actual calculation of voidage is simple: it is the amount of empty space divided by the total volume. Multiply length by width by height to find the volume in cubic centimeters.

## What is bulk density formula?

Bulk density (g/cm3) = Dry soil weight (g) / Soil volume (cm3) Bulk density is usually expressed in megagrams per cubic metre (Mg/m3) but the numerically equivalent units of g/cm3 and t/m3 are also used (1 Mg/m3 = 1 g/cm3 = 1 t/m3) (Cresswell and Hamilton, 2002).

## How do you calculate volume of water?

Calculating water volume depends on the shape of the vessel containing the water. Volume calculations for a square or rectangular vessel require you know its length, width and depth for entry into the volume equation, V=L_W_D, where L stands for length, W is the width and D represents depth.

## What is the density of 20mm aggregate?

(1) Bulk density of combined coarse aggregate 20mm and 12.5mm in the proportion 70:30. 1.6840 gm / cm³ (2) Bulk density of three aggregates i.e., CA 20mm : CA 12.5mm : FA is 42 : 18 : 40. (coarse aggregate 20 mm : 12.5 mm i.e., 70 : 30 as fixed earlier).

## What is soil void?

The voids in the soil mass represent the pores between the solid particles including the volume of water and the volume of air. Both volume of water and volume of air add up together and is said to be volume of void in the soil.

## Who is the father of soil mechanics?

Karl Terzaghi

## What does void mean?

having no legal force or effect; not legally binding or enforceable. useless; ineffectual; vain. devoid; destitute (usually followed by of): a life void of meaning. without contents; empty. without an incumbent, as an office.

## Can degree of saturation be greater than 100?

The degree of saturation (S) is defined as the ratio of volume of water to the volume of void. For dry soil, S will be 0%, and for fully saturated soil, S will be 100%. In fully saturated state, the complete volume of voids are filled with water. Hence, S>100% is not possible.

## Can water content be more than 100?

In soil Mechanics Water Content (w) = Weight of water/weight of Soil. Water Contains shows us in what percentage water is present in whole soil sample. soils moisture content can range from 0 to 300 percent. Water contain can’t be greater than 100% cause it’s impossible to get obtain marks greater than the total marks.
