• We offer a complete line of Rebound Hammers for
  the occasional user as well as the engineering
  professional. All hammers are spring activated
  and conform to ASTM C-805 as well as other
  European and Asian Standards. All are made to the
  most exacting machine tolerances to provide the
  end user with a consistent test every time.
• A Schmidt Hammer or a rebound hammer is a device
  to measure the elastic properties or strength of
  concrete or rock, mainly surface hardness and
  penetration resistance. Hammer test is done as
  per IS 13311 (part 2) -1992 or ASTM C805/C805 M
  or ACI 228.

  innovative and exceptional analytical process and
  methodologies that help industries
  organizations of all sizes to achieve
  predictable, improved product quality level,
  turnaround time cost associated with testing
  integrity requirements.
• Imagination is threaded into the very fabric of
  science and technology. It is the inspiration
  behind new thoughts and ideas for doing and
  creating things that once seemed impossible.

Testing Services

• REBOUND HAMMER
• Rebound hammer test is done to find out the
  compressive strength of concrete by using rebound
  hammer as per IS 13311 (Part 2) - 1992. The
  underlying principle of the rebound hammer test
  is The rebound of an elastic mass depends on
  the hardness of the surface against which its
  mass strikes. When the plunger of the rebound
  hammer is pressed against the surface of the
  concrete, the Spring-controlled mass rebounds and
  the extent of such a rebound depends upon the
  surface hardness of the concrete.
• The surface hardness and therefore the
  rebound is taken to be related to the compressive
  strength of the concrete. The rebound value is
  read from a graduated scale and is designated as
  the rebound number or rebound index. The
  compressive strength can be read directly from
  the graph provided on the body of the hammer.

  Test Calibration laboratory. Our calibration
  services are spread all over the India and
  overseas also.
• It include
• Calibration Of Rebound Hammer

Rebound Hammer Test Equipment

• A simple equipment known as Rebound Hammer or
  Schmidt Hammer is used for this purpose. Surface
  hardness measured during the test give an idea
  about the soundness and quality of cover
  concrete.
• Locations having very low rebound numbers
  indicate weak surface concrete and may be
  affected by corrosion. The quality of concrete
  may be interpreted as shown in the above table.

• SGM lab solutions was established with an aim to
  serve a wide variety of laboratory and NDT
  equipments. We believe in serving products of
  quality. we offer a complete range of Rebound
  hammer and RCPT including its testing
  calibration service. We provided accuracy and
  assurance for significant experiments.

Concrete Rebound Hammer

• Concrete Test Hammer, ideally suited for on-site
  tests of concrete and is widely used instrument
  for analyzing the uniformity and compressive
  strength characteristics of concrete structures
  and Detection of weak spots in the concrete.
  Rebound values are read from a scale for
  subsequent calculation of the mean. Compressive
  strength values can be read from a conversion
  diagram.

Digital rebound hammer

• Digital test hammers are an advanced, completely
  automated system for estimating concrete
  compressive strength. Its calculation, memory and
  recording functions allow for quick, easy and
  accurate test results.
• Discard values for multiple test results can be
  set the mean, median and compressive strength
  can also be calculated. The addition of modern
  microprocessor technology allows the data to be
  stored, printed and transferred to a personal
  computer for further analysis, or inclusion in
  your reports.

Schmidt Rebound Hammer

• The Schmidt rebound hammer is principally a
  surface hardness tester. The Original Schmidt is
  available in models with different impact
  energies, each test hammer designed for a
  specific test application.
• The Romans were aware of the fact that good
  mortar (opus caementicium) is hard and of a high
  compressive strength. They tested its quality
  subjectively by scratching the surface with an
  iron nail.
• But only in the mid-20th century was this
  know-how utilized. A device was invented which
  made non-destructive compressive strength testing
  feasible.
• It was and is the Original SCHIMIDT concrete test
  hammer

Digital Schmidt rebound hammer

• Digital Schmidt rebound hammer is the most
  advanced instrument in its category with follows
• The instruments body lies very comfortably in the
  hand. The display is highly readable under any
  conditions.
• A two-layer seal prevents dust and dirt from
  penetrating to the interior of the instrument.
• The forward and the rebound velocity of the
  hammer mass are both measured in close proximity
  to the point of impact. The rebound value
  requires no angular correction.
• A larger number of measurement points can be
  easily collected by the instrument and
  automatically evaluated according to statistical
  criteria.
• The application "Hammer link" allows all data to
  be uploaded via USB. Firmware upgrades are also
  possible over this connection

RCPT-Rapid chloride permeability test apparatus

• The PROOVE it system is used to evaluate the
  resistance of concrete to the ingress of chloride
  ions in two ways By determining how easy it is
  to force chloride ions into saturated concrete by
  applying an electrical potential across a test
  specimen in accordance with AASHTO T 277 or ASTM
  C1202. This is known as the "Coulomb Test" or the
  "Rapid Chloride Permeability Test (RCPT)." By
  measuring the penetration depth of chloride ions,
  after an electric potential has been applied to
  the specimen in accordance with NORDTEST BUILD
  492 (Chloride Migration Coefficient from
  Non-Steady State Migration Experiments) to
  determine the "Chloride Migration Coefficient,"
  which can be used to estimate the chloride
  diffusion coefficient for service life
  calculations.

• A water-saturated concrete specimen, 100 mm
  diameter and 50 mm thick, is positioned in a cell
  (right and page 104) containing fluid reservoirs
  on both sides. For the RCPT or Coulomb Test, one
  reservoir is filled with a 3 NaCl solution and
  the other with a 0.3N NaOH solution. A potential
  of 60 VDC is applied across the cell. The
  negative terminal is connected to the electrode
  in the reservoir with the NaCl solution and the
  positive terminal is connected to the electrode
  in the NaOH solution. The negatively charged
  chloride ions will migrate towards the positive
  terminal.
• The more permeable is the concrete, the more
  chloride ions will migrate through the specimen,
  and a higher current will be measured. The
  current is measured for 6 hours. The area under
  the curve of current versus time is determined,
  which represents the total charge or Coulombs
  passed across the specimen.
• Make Germann Instruments A/S, Denmark
• Model PROOVE'it
• Computer controlled microprocessor based system
  to measure the durability aspect of concrete
  structures The resistance to chloride ions.
  Testing of up to 8 cells simultaneously. Voltage
  setting at 10, 20, 30, 40, 50 and 60 VDC. Window
  based software for testing and reporting.
