Moisture Content T

l
i
o
Moisture content of soil is generally measured as a ratio of the weight of water to the weight of solids, expressed as a
S
percentage. As soil behaviour depends on its moisture content, it is one of the basic parameters defining the soil
condition.
To a quality 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 to some extent to decide 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.
Speedy Moisture Meter
ELC 036-1 & 037-1
Ref. Standards: BS:1377
Using a speedy moisture meter, the moisture content of soil, 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.
A conversion formula gives the corresponding moisture content based on
ELC 036-1
dry weight.

ELC 03601 Calcium Carbide Reagent 1 No.

This moisture meter has been designed for rapid and accurate
i
t
s determination of the moisture content of a wide variety of materials.
e
T It is torsion wire instruments, the torque being applied to one end of the wire
l be means of a calibrated drum to balance the loss of weight as the test
i
o sample dries under infrared radiation. The speed of drying (about 30 min)
S
thus obtained, combined with the frictionless balancing system gives the
result as accurate as those obtained by standard oven drying method. Since
drying weighing are simultaneous, it is useful specially for determination of
moisture in substances that quickly reabsorbs moisture after drying. The
infrared radiation is controlled by a voltage regulator and thereby provided
excellent heat control. The instrument is provided with an indicator lamp,
which glows when the unit is switched on. ELC 038
The torsion balance has a built-in magnetic damper or reduce pan vibrations that enables quick weighing. The balance
scale (drum) is divided in terms of moisture percentage 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.

Index Properties of Soil
Liquid Limit
The liquid limit defined as the moisture content at which the soil passes from plastic state to liquid state, is very helpful
for 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. The liquid limit of soil can be determined by Casagrande Method or
Cone Penetrometer Method.
Casagrande Method
ELC 040 & 041
Ref. Standards: BS 1377, ASTM D4318
Mechanical method known as the Casagrande Method
has been a standardised test in Soil Mechanics for
many years.

• Satisfies International Standards
• Motorised model with integral blow counter is

The Liquid Limit Device consists of a hard rubber base carrying a sliding carriage assembly to which a brass cup
is hinged. The cup is raised and allowed to fall through a height of 1 cm on to the hard rubber base, with the help of a g
lead screw provided at the back of the sliding carriage n

Plastic Limit
The plastic limit test is done to determine plastic limit of soil, as per BS-1377. The plastic limit of soil is the water content
of the soil below which it ceases to be a plastic. It begins to crumble when rolled into threads of 3mm dia.
