Laboratory Vane Apparatus

 

The new Wykeham Farrance laboratory Vane Shear Apparatus measures the shear strength of cohesive soils and is particularly useful for soils with low shear strength. Vane shear testing is a fast and economical method of measuring the shear strength of clay compared with elaborate triaxial shear or direct shear tests.
This apparatus tests undrained strength of soils, both in undisturbed and remoulded conditions.
