Determining the density according to DIN EN ISO 17892-2

Status: 10.12.2024

The density of the soil is the mass of the moist soil relative to the total volume of the soil, including the pores filled with liquid and gas. Derived quantities are:

  • Dry density: ratio between the mass of solid components and the total volume of the soil
  • Porosity n: pore volume relative to the total volume
  • Void ratio e: pore volume relative to the solid volume
  • Degree of saturation Sr: pore water volume relative to the void volume

These quantities are needed, for example, to determine soil weight, bulk density, in the Proctor test, when checking compaction work and when calculating other soil parameters.

The mass of the soil sample is determined by weighing. The volume is determined as follows, depending on the nature of the soil sample:

  • Measuring geometrically regular test specimens
  • Immersion weighing
