  • How to Conduct Consolidation Test of Soil? | Soil Engineering

    Consolidation test consists of applying the pressure on a thin soil specimen in increments and keeping each pres­sure increment for sufficient time until the consolidation of the soil specimen and measurement of the vertical deformation of the soil specimen due to expulsion of pore water. All consolidation parameters including a v, m v, C c, c v etc. can be determined from the consolidation test under each pressure increment.
