How to Calculate and Solve for Specific Gravity of Soil Particle | Soil Mechanics and Foundation

The image above represents specific gravity of soil particle. To calculate specific gravity of soil particle, two essential parameters are needed and these parameters are Density of water (ρ_w) and Density of soil (ρ_s).

The formula for calculating specific gravity of soil particle:

G_s = ^ρ_s / _ρw

Where:

G_s = Specific Gravity of Soil Particle
ρ_w = Density of Water
ρ_s = Density of Soil

Let’s solve an example;
Find the specific gravity of soil particle when the density of water is 22 and the the density of soil is 11.

This implies that;

ρ_w = Density of Water = 22
ρ_s = Density of Soil = 11

G_s = ^ρ_s / _ρw
So, G_s = ¹¹ / ₂₂
G_s = 0.5

Therefore, the specific gravity of soil particle is 0.5.

Calculating the Density of Water when the Specific Gravity of Soil Particle and the Density of Soil are Given

ρ_w = ^ρ_s / _Gs

Where;

ρ_w = Density of Water
G_s = Specific Gravity of Soil Particle
ρ_s = Density of Soil

Let’s solve an example;
Given that the specific gravity of soil particle is 12 and the density of soil is 156. Find the density of water?

This implies that;

G_s = Specific Gravity of Soil Particle = 12
ρ_s = Density of Soil = 156

ρ_w = ^ρ_s / _Gs
Then, ρ_w = ¹⁵⁶ / ₁₂
ρ_w = 13

Therefore, the density of water is 13.

Calculating the Density of Soil when the Specific Gravity of Soil Particle and the Density of Water are Given

ρ_s = G_s x ρ_w

Where;

ρ_s = Density of Soil
G_s = Specific Gravity of Soil Particle
ρ_w = Density of Water

Let’s solve an example;
Find the density of soil when the specific gravity of soil particle is 12 and the density of water is 9.

This implies that;

G_s = Specific Gravity of Soil Particle = 12
ρ_w = Density of Water = 9

This means that ρ_s = G_s x ρ_w
ρ_s = 12 x 9
ρ_s = 108

Therefore, the density of soil is 108.
