Classification tests

Classification tests to determine the properties of soils such as

  • Grain size distribution
  • Water content w
  • Atterberg limits for fine-grained soils including shrinkage limit, plastic limit, and liquid limit
  • Density, void ratio e, degree of saturation Sr
  • Bulk density
  • Loosest and densest state of non-cohesive soils (emin, emax)
  • Lime content
  • Loss on ignition
  • Water absorption capacity according to Enslin/Neff
  • Falling cone test
  • Permeability test
  • Proctor density and optimal water content
  • Friction angle for critical states (angle of repose test)

Furthermore, special tests can be carried out, amongst others

  • Abrasimeter
  • Suspension testing
  • Viscosimeter and rheometer
