### In Situ Density Test- Part 1 (Core Cutter Method)

In soil mechanics, No matter what you are calculating whether it's bearing capacity of soil or stresses in soil, you encounter with a term '

In simple language, we can defined Density of soil as ratio of Mass of soil to Volume of that soil (Mass per unit volume of soil).

Density,

γ= mass density of soil

W= weight of soil

V= volume of soil

For dry density we know,

where w= water content

For calculating the density of soil, there are number of field test. From which, we are going to discuss Core Cutter method.

**Density of soil**'. The density of soil is used in calculating the stresses in soil, Earth pressure beyond the Retaining wall, Dam, Embankment and Estimation of soil settlement under structural loads. It is also used in Field Compaction of soil and in many other method.In simple language, we can defined Density of soil as ratio of Mass of soil to Volume of that soil (Mass per unit volume of soil).

Density,

**γ= W/V**γ= mass density of soil
