INTERPRETATION OF RESULTS OF REBOUND HAMMER

INTERPRETATION OF RESULTS OF REBOUND HAMMER

The rebound reading on the indicator scale has been calibrated by the manufacturer of the rebound hammer for horizontal impact, that is, on a vertical surface, to indicate the compression strength. When used in any other position, appropriate correction as given by the manufacturer is to be taken into account. 

Hammer test can provide fairly accurate estimate of concrete compression strength, it performed with precautions and co- relations:

1.     Concrete Age: The concrete should be 14 to 56 days old.

2.     Surface Condition: The surface of the concrete at the point tested must be smooth dry and free of honey combing. Otherwise, rebound readings will be low indicating a weaker concrete than is actually the case .

3.     Location of Test Point: The concrete to be tested must be at least 100 mm thick. Care must be taken that the test points are no closer than 25 mm from the edge.

No. of Readings: Calculate the average of 10 readings and exclude extreme readings (if any) and recalculate average using the remaining readings

STRENGTH OF HARDENED CONCRETE BY REBOUND HAMMER

PROCEDURE TO DETERMINE STRENGTH OF HARDENED CONCRETE BY REBOUND HAMMER:

·         

       Before commencement of a test, the rebound hammer should be tested against the test anvil, to get reliable results, for which the manufacturer of the rebound hammer indicates the range of readings on the anvil suitable for different types of rebound hammer.

·         Apply light pressure on the plunger - it will release it from the locked position and allow it to extend to the ready position for the test.

·         Press the plunger against the surface of the concrete, keeping the instrument perpendicular to the test surface. Apply a gradual increase in pressure until the hammer impacts. (Do not touch the button while depressing the plunger. Press the button after impact, in case it is not convenient to note the rebound reading in that position.)iv) Take the average of about 5 readings.

Rapid Chloride Permeability Test (Rcpt)

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.

Digital Schmidt rebound 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 "Hammerlink" allows all data to be uploaded via USB. Firmware upgrades are also possible over this connection

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.

Digital rebound hammer

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.

Rebound Hammer Test

Rebound Hammer Test

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.
