Soil Properties & Resistivity

Soil properties to determine soil thermal resistivity testing by Tempsand

All soils are different so what makes up soil and how are they affecting soil thermal resistivity testing properties

Soil usually consists of three basic constituents.

1. Solids in Soil

  • In soil, solids can be anything from a clay particle to a gravel piece. Every solid can be made up of any element however the majority of soil particles are silicon or derivatives of silicon. Thermal resistivity or conductivity is usually dependent on the solids in the soil.

2. Voids in Soil

Usually voids in soil are air but can be made up of any gas.

3. Liquid in Soil

Most common of all liquids found in soil is water. Liquids can be any element that is in a liquid state at room temperature.

Now you probably noted I said above “usually consists of three basic constituents”. Soil can consist of just solids and water or solids and gas however theses states are rarely found naturally.  As discussed in an earlier blog; air is the enemy when it comes to soil thermal resistivity testing, so always try to remove the air with water where possible by forcing the particles closer together with compaction.
