Swell Test Apparatus Manual
It is designed to determine the swelling pressure
developed by soil specimens moulded to desired densities at known moisture
contents, when soaked in water. The load applied to restrain the swelling is
transferred to a load measuring proving ring through a perforated swell
plate and a load transfer bar. The proving ring is attached to the lead
screw of hand operated load frame. A soaking tank is provided for saturating
the specimen and the base of the mould has channels and radial grooves with

Laboratory Vane Shear Apparatus
Consists of a torque head, adjustable in height by
means of a lead screw rotated by a drive wheel to enable the vane to be
lowered into the specimen. Rotation of the vane is by means of an electric
motor which operates a worm gear arrangement turning the upper end of a
calibrated torsion spring. The vane shaft is attached through the hollow
upper shaft to a reset table pointer which indicates the angle of torque on
a dial graduated in degrees. The dial reading multiplied by spring factor
gives the torque.

Chequered plates and accessories
The Plate Bearing Test is essentially a model test
of foundations and gives the load deformation characteristics for
determining the ultimate bearing capacity of foundations. This test is a
standard technique for determining bearing capacity of soils and the results
of other methods are compared and calibrated with the values obtained with
plate bearing test. In this method, a steel plate is subjected to a gradual
increment of load and the corresponding settlement is noted. The Ultimate
Bearing Capacity is taken as the load at which the settlement increases at a

Unconfined Compression Testing Machine
Meets: - IS: 2720 (Part 10),
- Unconfined Compression Testing Machine, Manual
Unconfined Compression Testing of soil is a quick and simple method to
study the behaviour of soil. This is generally done on cohesive soils.
In this test, specimen is subjected to uniaxial compression without any
lateral support. The equipment can be used for determining the
unconfined compression strength of cohesive soil specimens of 38mm,
50mm, 75mm and 100mm dia size.
The equipment comprises of the following
- One loading unit, 50 kN (5000 kgf) capacity with three rates of

Grain Size Analysis (Pipette Method)
Meets:- IS 2720 (PART IV) AND BS 1377:2.
This is for the determination of the sub sieve particle distribution in a
soil sample by mechanical analysis. An analysis of this kind expresses
quantity the proportions by weight of the various sizes of particles present
in the soil. It is recommended as a standard procedure to use dispersion
agent to avoid flocculation. The apparatus consists of a sliding panel which
moves up and down by means of a screw allowing Anderson pipette fixed to it
to be raised or lowered vertically. A sedimentation tube is held by a
laboratory clamp provided on the stand below the pipette. The depth of
immersion is measured by a scale graduated in mm at the side of the sliding
panel. Supplied complete with Anderson pipette 10ml. At the side capacity
made from glass, and a sedimentation tube also of glass of 500ml capacity
and 50nos. Test form pads.

Shrinkage Limit Apparatus
Shrinkage Limit is the maximum water content at
which a reduction in water content does not cause an appreciable reduction
in volume of the soil mass. At shrinkage limit, on further reduction in
water, air enters into the voids of soils and thus keeps the volume
constant. The apparatus can be used to determine shrinkage limit and to
calculate other shrinkage factors like shrinkage ratio, shrinkage index and
Set consists of one each
