Soil classification
Soil classification is the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. A classification for engineering purposes should be based mainly on mechanical properties, e.g. permeability, stiffness, strength.

Shear Viscosity of Clays in the Fall Cone Test
This paper investigates the use of a fall cone test to determine the viscosity of clay soils with a liquidity index of less than one. Eight soils, including kaolin and 6 natural clay soils, were thoroughly investigated using the fall cone test. The results of the study show that the fall cone test is suitable to determine the shear viscosity of
