About us
  • SGM lab solutions an initiative of sigma test and
    research center which was established in 2009 by
    technocrat educationist who have over 30 years of
    experience in the area of education,
    administration, manufacturing and marketing.
  • SGM lab solutions came on floor with an objective
    to provide excellence in testing services,
    equipments, training, calibration, lab set up
    facility and aimed at providing its clients
    technology that is conducive to fast changing
    environment and backed by a group of
    professionals who have dedicated its formative
    years in quality control across various
    industries.

  • 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.

Mission
  • Our Mission at REBOUND HAMMER is to offer
    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.

Rebound Hammer Calibration
  • Rebound Hammer Calibration- Calibration of Anvil
    Rebound Hammer is what you will get here at Sigma
    Test Calibration laboratory. Our calibration
    services are spread all over the India and
    overseas also.
  • It include
  • Calibration Of Rebound Hammer
  • Rebound Hammer Calibration
  • Calibration Anvil Rebound Hammer
  • 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.
  • We constantly work harder to improve the over all
    quality within the industry. We are constantly
    bringing together the best technical expertise to
    provide viable and cost-effective solution to
    laboratories, while answering the need for
    affordable, outstanding and exceptional after
    sales services and support thus enabling our
    customer to attain the highest value for their
    purchases. We strive to advance people's
    knowledge and there ability to enhance their
    quality of life. Trust in a strong brand that
    stands for quality and innovation in the lab for
    decades.

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.

12
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.
