Objective of Rebound Hammer Test
As per the Indian code IS: 13311(2)-1992, the rebound hammer test have the following objectives:
To determine the compressive strength of the concrete by relating the rebound index and the compressive strength
To assess the uniformity of the concrete
To assess the quality of the concrete based on the standard specifications
To relate one concrete element with other in terms of quality
Rebound hammer test method can be used to differentiate the acceptable and questionable parts of the structure or to compare two different structures based on strength.
Principle of Rebound Hammer Test
Rebound hammer test method is based on the principle that the rebound of an elastic mass depends on the hardness of the concrete surface against which the mass strikes. The operation of the rebound hammer is shown in figure-1. When the plunger of rebound hammer is pressed against the concrete surface, the spring controlled mass in the hammer rebounds. The amount of rebound of the mass depends on the hardness of concrete surface.

Thank you so much very helpful information
Very good sir...thank you so much...i am going for testing next week...
Explain method very good 👍
This was easy to understand sir thanks
amazing video and the way you explained is so easy to understand. thanks
Pls share if like
Very good information
Nice explain please add much more videos like digital rebound hammer test
Thank you very much 🙏
O its nice and so simple..Keep it up
In IS code mentioned that, we have to derive correlation curve between compressive strength and Rebound numbers. From that we will get compressive strength.
excellent videos
Sir i am understand rebound hammer test thanks sir
Very good sir 🎉🙏
Very good👍
Good sir 👌👍
Thank you so much sir
Good job
Super sir.....
Excellent
Thanks sir
Hello sir.. Thank you all of you. For this all important videos.
Thank ...welcome
Nice
Thankyou
Good
Super🙏
please share price detail and brand of this hammer
Horizental angle is center point than vertical is which point scale sir
How test old building strength
Column M20 1 month ke bad kitni aani chahiye??
can we hammer the concrete more than 56 days?
Graph thoda clear kijiaa......
What is the curve line indicate
Ye graph kaha se download kre soft copy
Iska kita reading aata h grad shelf ka
Rebound hammer test kab krte hai
retaining wall k slop m check krna ho to kon s angle lge gaa ...??
Hammer to perpendicular hi rahega bhai..
How this price
Hardness test hota h na ki compressive strength
I think your explanation of +ve and -ve scales are opposite?
Ok bro i will check
Where you from taken this specific data sir pls tell us
IS Code 13311.2.1992
@@HIGHWAYENGINEERING 0,delaminated
20 poor
20,30 fair
Where from you taken these data sir pls tell us with reference because if someone asked about this satisfy them
Thank you sir
Sir this gragh not given is 13311 part 2 , please guide where this gragh is shown reply soon
Graph is pasted by manufacturer on Hammer
@@HIGHWAYENGINEERING we have purchased rebound Hammer but there is no graph pasted on device as well as not in the suitcase carring device. Our device is digital having display also , Please guide waiting
Slab ki strength bhi is test se check ki jati hai kya sir??
Plz reply
Yes
@@HIGHWAYENGINEERING thank u sir
what is the purpose this test
To determine strength of concrete. With out any damage
Graph mey five lines hey .....to ap ne ku middle line mey touch ku kia ....??
Middle line 0° angle bali he isliye...Kuki hammer horizontal liya he
Diffrant Line are indicate different angle
@@HIGHWAYENGINEERING m
Is equipment ki cost kitni hogi?
~~~ ₹ 7000/- -- ₹ 15000/-
Thanks sir
Nice
Good
