The fall cone apparatus, first introduced in 1915, provides a rapid simple and accurate method for determining empirically the undrained shear strength, the shear strength of remoulded samples and thus the sensitivity of clays. the equipment is also used for determination of liquid limit (LL). Four cones of different weight and apex angle are provided.
