Concrete Testing Machines
Flexure Strength
IS: 516, IS: 9399, BS: 1881, and ASTM C78.
The Flexure Strength Testing Machines are designed to provide maximum
rigidity throughout their working range. The downward movement of Hydraulic
ram applies the load. The jack can be raised or lowered for testing
different size beams. The load is indicated on a calibrated Bourdon tube
type load gauge of range: 0-100KN X 0.5KN (0-10,000 kgf X 50 kgf). The load
gauge is calibrated against NPL/NCCBM certified proving ring.
Flexure Strength Testing Machine (concrete slabs)
IS:4969
This Flexural Strength Testing Machine is designed to suit the requirements
to test precast Cement Concrete slabs for Canal Lining. The machine consists
of a Bench Mounting type loading unit having a capacity of 25kN (2,500 kgf)
with a self retracting type jack and a hand operated hydraulic pump. A 25 kN
x 0.25 kN capacity pressure gauge, with maximum load indicating pointer, is
attached to the pump. The machine has a set of platens, the top platen has a
self aligning roller fixed at the centre and the lower one has two rollers
of 25 mm dia, equally spaced at a distance of 15 cm. These rollers are hard
chrome Plated to increase the abrasion resistance and hardness. Suitable for
operation with 230 volts, 50 Hz, and single phase, AC Supply
Available Models are :
- IL - 135 - Loading capacity 25 KN Manually operated
- IL - 136 - Loading capacity 100 KN Manually operated
- IL - 137 - Loading capacities 100 KN Motorised
Flow Test
IS: 1199, ASTM C124, AASHO T120, and T126
The Flow Table is designed for determining the workability of Portland
cement concrete. The Flow Table top is 76.2 cm dia, finely machined from a
solid brass casting. The integral cast ribs are designed for support and
strength. The stand is fabricated out of cast iron and is of sturdy
construction. Holes for mounting of foundations are drilled in the base
plate. The ground and hardened steel cam is designed to drop the table by
12.5 mm. The following model is offered :
IL - 138
IS: 712
Flow Table Manually Operated Having table top 30 cm made of M. Steel
IL - 139
IS: 5512
Flow Table, Motorised
Having tabletop 25 cm made of M. Steel with an electric motor suitable for
operation with 230 volts, 50 Hz, and single phase, AC Supply.
IL - 139.1
IS: 5512
Flow Table, Motorised
Having table top 76.2 cm made of M. Steel with an electric motor suitable
for operation with 230 volts, 50 Hz, single phase, AC Supply.
Hydraulic Jacks
Hydraulic Jacks have multipurpose utility, i.e.
application of loads while engaged in field investigation, determination of
load carrying capacity of piles in the field, tensioning of wires in
pre-cast structures, loading of members of any structure for deformation
characteristics, etc. The jacks are supplied complete with manually operated
pumping units fitted with Bourdon tube type pressure gauge and a
steel-connecting pipe. All the jacks have a piston travel of 75 mm and jacks
up to 500 KN capacity are provided with retraction springs. These are
available in the following ranges :

Note : For all the above-mentioned jacks,
the piston travel can be made 150 mm, if specified while ordering, at an
extra cost. High Pressure Flexible Hose Pipe is required for connecting the
pumping unit to the Hydraulic Jack. This is an essential extra to be ordered
with any of the above jacks. The hose pipe is available in varied lengths as
tabulated.
