Sand Replacement Method
Sand Pouring Cylinder Apparatus, IS: 2720 (Part 28)
This Apparatus is used for determination of the dry
density of compact, fine, medium grained soils and for layers not exceeding
50 cm thickness. A circular hole is dug into the ground, all the soil from
within it collected, weighed and dried, and the hole back-filled with a
standard uniform sand or fine gravel, poured from a calibrated container for
calculating the volume of hole. The apparatus consists of the following:

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.

The Shrinkage Limit of a soil is defined as the
moisture content at which any further reduction of moisture will not cause
volume reduction. The shrinkage of clayey soil can be very significant. A
fully saturated soil specimen is allowed to dry in free air and its volume
is measured repeatedly by immersing in a mercury bath. From the data
obtained from this test, Shrinkage Limit, Shrinkage Ratio, Shrinkage Index
and Volumetric Shrinkage can be calculated. The choice of puddle clay
materials is often governed by the results obtained from this test.

Particle Size Analysis
The analysis of soils by particle size provides a
useful engineering classification system from which a considerable amount of
empirical data can be obtained. This helps in ascertaining possible frost
action, determining graded filters, selection of grouting materials,
designing of cement and asphaltic concrete mixes, etc. Two different
procedures are used for coarse and fine soils. Sieving is used for gravel as
well as sand size particles and sedimentation procedures are used for finer
soils. For soils containing coarse and fine soil particles, it is usual to
employ both sieving and sedimentation procedures. SHIVAM provides the
following range of equipment for performing particle size analysis.

To make the process of sieving easier and quicker,
electrically operated mechanical Sieve Shakers are offered for dry sieving.
These Sieve Shakers are popularly used not only in soil laboratories but
also in a number of industries where sieving is required; such as for ores,
refractory materials, minor aggregates, pigments, powdered coal, soap,
cement, roofing materials, plastic moulding powders and pharmaceuticals. The
Sieve Shaker can carry up to 7 sieves.

It is driven by a ¼ HP motor. The Sieve Table is inclined from the
vertical axis and the direction of Inclination changes progressively in the
clockwise direction. In addition to the gyratory motion of the table, there
is a tapping motion as well.

is given by hammer from the top. The shaker takes 8" Or 6" sieves.
The shaker is recommended for I.S.S tests.
IS: 2720 (Part 2); BS: 1377, 1924 and ASTM D2216
Moisture content of soil is generally measured as a
ratio of the weight of water to the weight of solids, expressed as a
percentage. As soil behaviour depends on its moisture content, it is one of
the basic parameters defining the soil condition. To a control engineer,
even a rapid moisture content check is extremely useful, as it gives an
indication of the existing characteristics of the soil, which enables him
some extent to decide on the pattern of test programme. A number of
procedures have been suggested for carrying out water content tests in IS :
2720 (Part 2); BS : 1377, 1924 and ASTM D2216. The equipment listed below
gives a range of suitable apparatus for this purpose..
Infra-Red Moisture Meter
IS: 2720 (Part 2) - 1973
This moisture meter has been designed for rapid and accurate determination
of the moisture content of a wide variety of materials. It is a torsion wire
instrument, the torque being applied to one end of the wire by means of a
calibrated drum to balance the loss of weight as the test sample dries under
infrared radiation. The speed of drying (about 30 min) thus obtained
combined with the frictionless balancing system gives the results as
accurate as those obtained by standard oven drying method. Since drying and
weighing are simultaneous, it is specially useful for determination of
moisture in substance, that quickly reabsorbs moisture after drying. The
infrared radiation is controlled by a voltage regulator and thereby provides
excellent heat control. The instrument is provided with an indicator lamp.
The torsion balance has a built-in magnetic damper to reduce pan vibrations
enabling quicker weighing. The balance scale (drum) is divided in terms of
moisture percentages on wet weight basis, which are read directly from it.
Graduations are from 0 to 100% in 0.2 % divisions, but readings may be
estimated to 0.1 % moisture content. It is a portable unit, supplied
complete with one Infra-Red Lamp and Thermometer. Suitable for operation on
230 V, 50 Hz, Single phase, AC Supply.

Speedy Moisture Meter
IS: 2720 (Part 2) - 1973 IS: 12175-1987
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.

Standard Penetration Test Set
Standard Penetration Test is a powerful tool for measuring the penetration
resistance of the ground and relating it to the degree of compactness of
cohesion less soil and consistency of cohesive soil. The results can be used
for design of foundations. SPT is widely used for measuring the undisturbed
strength of the soil and for assessing its resistance to liquefaction due to
ground vibrations caused by earthquakes or other dynamic forces. The
Standard Penetration Resistance is measured as the number of blows 'N'
required to drive a split spoon sampler to a depth of 300 mm using a 65 kg
weight falling freely through a height of 750 mm.
