Permeability Appartus (Three Cell Model)
Specification:
The concrete permeability apparatus comprises of a mild steel cell of
Square/Round cross-section mounted on a stand and a pressure chamber is
connected to the cell through copper tubing and T-connector mounted on the
stand with sleeve packed valve and rubber hose pipe with end connections.
The cell assembly consists of one base plate and one top plate connected to
nozzles.
The pressure chamber is fitted with a pressure regulator which helps in
regulating the pressure from 0-15kg/cm sq. Gauge is for indicating the
pressure in the cell. A foot pump and a pressure tube is supplied to develop
pressure in the chamber. The apparatus is supplied with a measuring cylinder
500cc to measure percolated quantity to water
Hydraulic Jacks
Specification:
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-stressed 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 load gauge
and high pressure flexible hose pipe. All the jacks have a piston travel of 50 mm
and jacks upto 1000 kN capacity are provided with retraction springs.
Rapid Chloride Permeability Tester
Specification:
Complete rapid chloride ion permeability tester includes the following items:
RCPT test apparatus with 4 port (230~250 V AC power supply)
Plexiglass chambers - 4 pairs
300mm vacuum desiccator
Vacuum pump with gauge
Moisture trap
Temperature probe
Tests sealant + gun acrylic sealer + brush
Air Entrainment Meter
Specification:
The apparatus consists of a pressure tight flanged cylindrical measuring
bowl. The bowl is fitted with a removable flanged conical cover assembly
with the help of a seal. The conical cover has an air valve and a petcock for
bleeding off the water. A transparent cylindrical stand pipe which is
graduated in air content is fixed to the conical cover assembly. Pressure is
applied to the specimen with the help of a pressure bulb and the pressure is
recorded on the pressure gauge which is mounted on the stand pipe. The
whole assembly is mounted on a flat base. The instrument is supplied
complete with one each following accessories.
Calibration cylinder with spring clamp, trowel, tamping rod, straight edge.
Rubber mallet and measure.
Concrete Test Hammer (Schmidt Hammer) N Type
Specification:
The quality of concrete is mainly judged by its
compressive strength directly affecting the loadbearing capacity and durability of concrete structures.
ZI 2068 concrete test hammer (Schmidt Hammer N
type) is used to measure the compressive strength
characteristics of hardened concrete non-destructively,
control uniform concrete quality and detect weak spots
in the concrete. The test object should have a minimum
thickness of 100 mm.
Crack Width Ruler
Specification:
This simple gauge has been designed to provide
inspectors with a low cost alternative to a graduated
microscope for determining the width of a crack in a
concrete or other building materials.
Similar in size to a standard credit card, this transparent
gauge is marked with a range of graded lines. Each line is
a specified width. To use, position the gauge over the
crack and identify which line is a similar width to the crack.
Read off the width value
Electronic Concrete Test Hammer (Schmidt Hammer)
Specification:
Power Electronic
Usage Compression strength
Test Range 10~60MPA
Standard Impact Energy 2.207j (0.225kgf.m)
Stroke of Rebound Hammer 75 mm
Friction of Pointer Slider 0.5n~0.8N
Shell High Polymer Material
B Type Air Entrainment Meter
Specification:
High-quality type B pressure meters measure concrete air
content and include many value-added improvements. Our
standard model now features the exclusive Gorilla gauge, and
a new, more affordable model offers an American-made
stainless steel gauge. Other features of the two units are
identical. Long-lasting stainless steel clamps adjust quickly and
are less expensive to replace. Pump with large, easy-grip
handle builds pressure quickly and is shielded to keep dirt and
water out of the piston area. Brass petcocks have stainless steel
ball valves for accuracy and durability. Petcock handles are
vinyl coated for more comfortable operation.dimensions and
accuracy of the meters exceed ASTM requirements. Calibration
vessel, calibration tubes, 24in (610mm) tamping rod,
aluminum straightedge, syringe for water, carrying case and
operating instructions are all included. Cast aluminum
chamber volume is 1/4ft³ and can also be used for unit weight
and yield determinations. Sturdy plastic carrying case holds
meter with all accessories securely in die-cut foam padding.
Case Dimensions: 686 x 356 x 356 mm (W x D x H)
Testing Anvil For Mechanical& Electronic Hammer
Specification:
Accessory for calibration check in situ the mechanical and
electronic hammer
ULTRASONIC PULSE VELOCITY TESTER
Specification:
The velocity of ultrasonic wave in concrete is affected by elastic
property or strength. Ultrasonic applies high voltage and sends
it to transit transducer to generate ultrasonic wave. This
ultrasonic wave reaches to the receive transducer through
concrete. When elastic property or strength of concrete is high,
the transit time is short. On the other hand, when the materials
are contrary, the velocity is low. Ultrasonic measures the
ultrasonic transit time accurately so it makes possible to
evaluate a material or find an elastic properties nondestructively to investigate uniformity, cavities, cracks,
fire/frost damage, delaminating, deterioration and strength.
We use 52 khz concrete transducers which was designed to
send and receive ultrasonic signal effectively in highly
extenuative materials, including concrete, wood, stone and
plastic. This instrument was developed by cooperative research
with research institute of standard & science, subsidized from
the national coffers of ministry of science & technology. This is
the 4th generation.
