Concrete Test Hammer

Concrete Test Hammer

- (SICNCTH -01)
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

Salient Features Specifications
  • Consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar.
  • A plunger is attached to the guide bar which is pressed against the surface to be tested.
  • As the piston is pressed against the surface to be tested.
  • As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent (according to the strength of the surface) which is indicated by a rider on a calibrated scale.
  • A lock button fixed on the body of the hammer locks the rider in place and the rider can be recared to zero position by using the same button.
  • The equivalent compressive strength can be computed from the chart supplied.
  • Each hammer is calibrated against at standard test hammer, and is suitable for specimen of compressive strengths 100 - 700 kg/cm.
  • The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.

Concrete Resistivity Meter

- (SICNCRM - 02)
Concrete surface resistivity meter provides information about the state of concrete structure. It is directly linked to the likelihood of corrosion and the corrosion rate .A direct correlation between resistivity and chloride diffusion rate has been indicated.

The applications include
  • Estimation of the likelihood of corrosion
  • Indication of corrosion rate
  • Correlation to chloride permeability
  • On site assessment of curing efficiency
  • Determination of zonal requirements for cathodic protection systems
  • Identification of wet and dry areas in concrete structure
  • Indication of variations in the water/cement ratios within a concrete structure
  • Identification of area within a structure most susceptible to chloride penetration
  • Correlation to water permeability of rock

Cover Meter and Rebar Locator

- (SICNRL - 03)
Rebar detector are designed for locating and or scanning of rebar in concrete and measure depth, identify rebar size, rebar diameter & corrosion in concrete before drilling and before core test or to find out physical condition of building, structures, roads & highways etc.

Rebar locator & corrosion detectors provide fast, accurate information to detect reinforcement bars in concrete, identifying rebar’s location, direction and an indication of the depth of concrete over the rebar.

Rebar locators & cover meters are offered in varying degree of capabilities: from basic cover meters which locate rebar & measure rebar depth to comprehensive rebar scanners generate 2D & 3D maps of rebar in concrete.

Corrosion Analysing Instrument

- (SICNCAI - 04)
Rebar corrosion detector are high performance based on half-cell potential NDT instrument that is utilized to examine the active corrosion in rebar in buildings & structures and provides the capability to detect extent of corrosion in concrete structures.Accurate measurement of the rebar corrosion rate is necessary for estimating the remaining service life of concrete structures, scheduling repair or maintenance operation.

Concrete Maturity Meter

- (SICNCMT - 05)
4-Channel Concrete Maturity Meters are used for assessing the strength of in-place concrete based on its age and temperature history.

The Type T thermocouple wires have quick-connect jacks for direct embedding into a concrete structure to measure the temperature at specific intervals. Concrete maturity indicates how far curing has progressed. Maturity is the relationship between concrete temperature, time, and strength gain. It is represented by an index value that can be measured in real time in the field.

Concrete Thickness Gauge

- (SICNCTG - 06)
The Concrete thickness gauge measures concrete slab thickness without drilling. The CTG-2 is a nondestructive system for measuring the thickness & integrity of concrete slabs. The Concrete thickness gauge detects: voids, honeycomb areas, cracks and delamination.

D-TECT 150 - Rebar Locator

Detects ferrous and non-ferrous metals, wood, live wiring and plastic pipes - metal detection in concrete up to 6 In. deep - note that live wires may not be detected in certain conditions such as in metal conduit or behind metalized or conductive surface.

Half Cell Potentiometer

- (SICNHCP - 07)
The Half Cell Potentiometer is used to measure the half-cell potential of reinforcement steel in concrete (in accordance with ASTM C876) for assessment of corrosion in steel reinforcement.

Pull-Off Adhesion Tester

- (SICNPOAT - 08)
Portable pull-off adhesion testers measure the force required to pull a specified diameter of coating away from its substrate. This measured pull-off force provides a direct indication of the strength of adhesion between the coating and the substrate.Pull-Off Adhesion: are simple to use, quantitative range giving a definitive adhesion value, ideal for the laboratory or field on flat or curved substrate applications. Tensile Dollies (or stubs) are glued to the coating and, when the adhesive has cured, the force required to pull the coating off the surface is measured.

Pull-Out Tester

- (SICNPOT - 09)
A pullout test measures the force required to pull a. specially shaped steel rod or disc out of the hardened concrete into which it has been cast. Because of its shape the steel rod is pulled out with a cone of concrete.Pull out testing involves attaching a suitable test rig to the bolt, screw, anchor or fixing. This is then put under tension to the designed stress load level to determine how strong and secure the fixing is.
