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
