Introduction

With the utilization of the non-destructive "rebound hammer test," the impressive strength of the concrete can easily be determined.

Yes, do you want to know more about it? So, in today's article, we will discuss the rebound hammer test in detail.

Read the entire article to learn about this Non-destructive Testing Method. 

Rebound Hammer — What Is It? 

Rebound Hammers Test, also known as Concrete Test Hammers, Swiss Hammers, and Schmidt Hammers, which are multipurpose equipment utilized to examine the integrity and quality of hardened concrete.

Even if its primary purpose is to specify the compressive strength of the concrete, rebound hammers have many more things to offer. 

Nonetheless, when evaluating a concrete building or structure, strength is not the only point that must be focused on!

The hammers are simple to utilize worldwide; this says that their results and performances have been reviewed very well.

What is meant by the Rebound Hammer Test?

When it comes to the Rebound Hammer Test, it proves itself the best in the matter of quick & effective collection of information on the homogeneity & quality of concrete in freshly created buildings or those that have been there for years.

It is a direct NDT Testing process that tends to provide a straightforward picture of the condition of the concrete, catches attention towards the parts with less strength, and highlights the regions that have been harmed by fire or something else.

It becomes simple to grab hold of better compressive strength values utilizing correlation data from laboratory experiments. 

When the hardened concrete is struck with the help of a test hammer's piston, a spring mechanism is then loaded until & unless it trips, which results in releasing the hammer mass.

Moreover, an already determined energy quantity is transferred from the mass when it strikes the piston to the concrete.

The rebound number value, also known as the R-value, is recorded by a simple linear scale because the hammer mass slips along an indicator.

When compared to the results from laboratory experiments, Schmidt found that these surface hardness values may display relative strength.
