Testing Service

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.

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.

Portable and flexible
Simple and convenient to use
Impact energy: 0.735 Nm
Measuring Range: 10-70 N/mm2
Conforms to BS-1881-202, ISO/DIS 8045, ASTM C-805

Rebound Hammer and their Types



A rebound hammer is an instrument to determine the durability of rock or concrete. Since this is an essential factor of architectural design and is specified for conformity reasons, it is vital to know the durability of the concrete. This hammer is also known as the Schmidt Hammer. The rebound hammer test is based on the most crucial that the rebound of an elastic mass relies on the solidity of the outer lining area against which the huge impinges. When testing the effect secure of the rebound hammer attacks the outer lining area of the concrete with a described power. After the effect, a steel body, the so-called hammer rebounds. 

Types of Rebound Hammer:

1.       Concrete Rebound Hammer

2.       Digital Rebound Hammer

3.       Schmidt Rebound Hammer

4.       Digital Schmidt Rebound Hammer

5.       RCPT (Rapid Chloride Permeability Test)

 
1.       Concrete Rebound Hammer:

Concrete Test Hammer, preferably suitable for on-site assessments of concrete and is widely used device for analyzing the consistency and compression strength characteristics of concrete structures and Recognition of poor areas 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.

2.       Digital Rebound Hammer

Digital test hammers are a high level, completely automated system for calculating 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.

3.       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.

4.       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 needs no angular modification.


5.       RCPT (Rapid Chloride Permeability Test)

The PROOVE´ it system is used to evaluate the resistance of concrete to the ingress of chloride ions in two ways:

By identifying how simple it is to force chloride ions into saturated concrete by implementing an electrical potential across a test sample according to AASHTO T 277 or ASTM C1202.  This is known as the "Coulomb Test" or the "Rapid Chloride Permeability Test (RCPT)."
