SPEEDY MOISTURE METER

MODEL: -GT-023
As Per IS 2720 (P-II), ASTM D 4944 AASHTO T 217
Specification :
Moisture content of soil is generally measured as a ratio of the weight of water
to the weight of solids, expressed in percentage. As soil behavior depends on its
moisture content, it is one of the basic parameters defining the soil condition.
The ‘Moisture’ content of soil, can be obtained quickly with reasonable accuracy
by using a Speedy Moisture Meter. The test technique is based on the fact that
water will react with calcium carbide to form acetylene gas. The quantity of
acetylene gas produced is indicated on a built- in pressure gauge. A conversation
formula gives the corresponding moisture content based on dry weight. Each soil
test equipment is supplied complete in a wooden carrying case consisting of
pressure vessel with clamp for sealing cap, rubber sealing gasket, pressure
gauge in percentage moisture content 0- 25% or 0-50% on the wet weight basis

the torque being applied to one end of the wire be 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 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. 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. Suitable for operation on 220
V, 50Hz, Single phase, AC Supply.

DYNAMIC CONE PENETRATION TEST

MODEL: -GT-079
The Dynamic Cone Penetrometer (DCP) is used for rapid in-situ measurement
of the structural properties of exsisting road pavement constructed with
unbound materials.The unit incorporates an 8 kg weight having a drop of 575
mm, fitted to the end of the shaft is a 20 mm diameter cone. With the standard
DCP measurements can be made down to a depth of approximately 850 mm.
Readings are usually taken after a set number of blows, changing the number
according to the strength of the layer being penetrated. For good granular
bases, readings every 5 – 10 blows are satisfactory, but for weaker sub-base
layers and subgrades, readings every 1 – 2 blows may be appropriate The DCP
requires three operators, one to hold the instrument in a vertical position, one
to raise the hammer and let it fall and one to record the results. A typical test
takes only a few minutes, providing a very efficient method of obtaining information which would otherwise require the
excavation of test pits. Where pavement layers have different strengths, boundaries can be identified and layer thickness
determined

light weight concrete, special roof deck mixes and concrete
additives.

Specification : Consists of a needle having face area 3/10 sq. cm.

and graduated at a distance of 25cm. The needles point is an integral
part of barrel which houses a calibrated spring. The spring is
confined in a sleeve. The resistance offered by the concrete mortar is
shown on the direct reading scale with a marker ring which holds its
2
position when released. 2 Scale range is 0-50kg/cm when the
2
penetration resistance reaches a 2 value of 35kg/cm the concrete is
assumed initially set. Supplied complete in carrying case.

Concrete Test Hammer (Small)

The concrete test hammer is an instrument which is easy to use, for
quick and approximate measurement of the resistance to pressure of
manufactured concrete products. The principles on which it works
are based on the rebound impact of a hammer on a piston which
rests against the surface of the concrete products. The Greater the
resistance of the concrete, greater is the rebounded impact. By
reading this rebound impact on a scale and relating it to curves on
graphs supplied with the instrument, the resistance to compression
in MPa or PSI can be found, with 20% of actual.
