Soil Testing Equipment
The liquid limit, defined as the moisture content at which the soil passes from the plastic state to the liquid state, is very helpful in the classification of the potential properties of the soil material. The liquid limit gives a measure of the shearing resistance which a soil has when mixed with water. Casagrande Method or Cone Penetrometer Method can determine the liquid limit of soil.

Proctor Compaction Apparatus
Proctor Compaction Apparatus
Compaction : Soil compaction is a
fundamental requirement for the construction of earth fill for dams,
reservoirs, canal embankments, highways, railways and runways. The
relationship between soil moisture content and compacted dry density is very
useful for deciding construction specifications and quality control of
compacted earth fill. While designing an earth or earth retaining structure,
the strength and deformation behaviour of soil is evaluated by testing soil
specimen compacted to the density as would be achieved during construction.
The construction quality control is essentially to check the density of
compacted soil achieved in the field, thereby checking its strength.

Consolidation
Consolidation test is un-dimensional test considered
extremely important in soil mechanics. Sample taken from adjacent areas of a
single site show differential settlement even when tested using same
techniques. Soil of similar strength may show varying consolidation. Samples
are very carefully prepared and vertical settlement of the specimen in
saturated or drained conditions carefully recorded when known load is
applied.

Sensitive Volume Change Gauge
Sensitive Volume Change Gauge
The Volume Change Gauge illustrated works on the
principle of reversing the direction of flow when the limit of the volume
change scale is reached. The number of cycles with the volume of fluid
handled in each cycle provides the total volume change, whereas the
sensitivity is governed by the dia of the polythene tube used.
The sensitive volume change gauge has realized sensitivity of 0.003 ml/mm with the 6 ml volume of fluid per cycle. The apparatus consists of a volume measuring polythene tube running along both sides of a scale and connected at both ends to two mercury traps. These traps are connected to flow reversal valves through a manifold. The length of the polythene tube is enough to measure 6 ml volume of fluid per cycle. A small pallet of mercury is introduced in the circuit to be used as a cursor, and the movement of pallet is measured. The unit is tested to a pressure of 20bar (20 kg/cm2) and is designed for wall mounting.

Speedy Moisture Meter
Speedy Moisture Meter
Using a speedy moisture meter, the moisture content
of soils, sand and other fine-grained material can be obtained quickly with
reasonable accuracy. The test technique is based on the fact that water will
react with calcium carbide to form acetylene gas and the quantity of gas
formed is directly proportional to the water present, leaving a surplus of
the chemical used in the test. The quantity of acetylene gas produced is
indicated on a built-in pressure gauge, which is calibrated in percentage of
moisture on wet weight basis.

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.

Plate Bearing Capacity
Plate Bearing Capacity, with 30, 45, 60 cm sqr. 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
rapid rate.

Grain Size Analysis
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 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
volumetric shrinkage.
