Laboratory Vane Shear Test

The test, is performed as per IS : 2720 (Part XXX), is suitable for estimation of undrained shear strength of cohesive soils of low shear strength. The equipment listed below satisfies the requirements of IS : 2720 (Part XXX).

Laboratory Vane Shear Apparatus, Hand Operated

HS 22.95

The apparatus comprises of the following :-

  • A torque applicator having a base with a hole for holding the specimen mould in position, supporting frame carrying torque head adjustable in height and a graduated drum to measure the deformation of springs.
  • A set of four springs, one each of 2 kg cm, 4 kg cm, 6 kg cm and 8 kg cm.
  • A vane of size 12.0 x 24.0 mm long with a vane rod.
  • Specimen container to take a specimen of 50 mm dia x 75 mm high.
  • Wooden carrying case for the complete apparatus.

Laboratory Vane Shear Apparatus, Motorized

HS 22.100

Same as HS22.95 but torque head is electrically driven by a small reduction geared motor with a strain rate of 6o per minute approximately.
