Hi John, this is a tension load test, also known as a pull out test. The product being tested here is a internally threaded anchor fastnerer designed to be used in precast hollow core slabs. A hydraulic jack is used to apply the load onto the anchor. The purpose of this test is to check the ultimate failure load of the anchor. In the case of the anchor being tested for this particular video the substrate, hollow core slab, failed at a load of 25kN
Hi Tommy, the failure load is 25kN, about 2500 kgs in a hollow core slab. Anchor tested was a internally threaded sleeve anchor with a trade name of MUNGO MHDA size M12.
@@acbautocustoms4587 hello, thank you for watching. In this video we aren't testing the strength of the concrete but actually testing a Mechanical anchor which is used in hanging MEP services. Its an expansion anchor which is specifically designed to be used in Hollow core slabs like the one you see in the video.
@@zaheerh is it only for anchor bolt break test? how about knowing the porosity or mix of concrete that will receive embedded anchor bolts to tell if its a good concrete or not capable to receive mechanical fasteners?
Hello, unfortunately we are only based in Dubai. But I am sure there will be several agencies who can provide this test in the Philippines. Best bet is to contact the anchor manufacturers representative for your area.

Concrete has almost no tensile strength. It's designed to have all of its strength dedicated to compressive loads. That's why concrete is always reinforced with rebar and/or mesh, to add to it's tensile strength.

Basically the anchor is as as good as the substrate?
@@jimdiet8534 In this case, Yes. However, there are times when the anchor fails too
Thank you for sharing this video. I can use this video to show to the contractor what is pull-out test.
Please do, glad to have been of help.
thanks for the video!! about to go do this to a metal roof and wanted to make sure i knew what i was doing
Very good video.Thanks
This is not a representative test. The cone is being pressed back by the test. This is a semi-confined testing situation.
That’s is correct, but only to a certain extent. I will try and put out an explainer video soon
Nice, thank you very much!
Thabks for the video, but I have a doubt, which norm did you follow to run this test?
Donde puedo sacar la licencia en new york ? Gracias
how to calculate compressive strength of concrete
Where did you purchase the pull testing device?
How much is the price?
Thank u for the video
is there any standard that specify which max load to apply for epoxy anchor bolts on foundations?
Jk
Hjn
What is the compressive strength of the specimen then?

Professional scaffolder.. whats the load at failure also what size anchor. sorry gauge isnt visible enough

@@zaheerh Hi Zaheer, so what is the required load you need to go thru in order to conclude that a concrete is strong enough and pass the test.

Load at failure was about 25 kN or 2500 kgs approximately.

@Zaheer Hussain What's the reading at the failure? What's your target force?
Hello @gnid, we were trying to reach the ultimate load that the anchor can carry which in this case was about 23kN
@@zaheerh Thanks.
do we perform this test on Philippines?

@@zaheerh May I know the brand or model of the tester used?
Can this equipment do a shear load test on 12mm chemical anchor bolt at 12kn without damaging the strength of the bolt.
Shear load tests are not possible with this kind of testers. They can apply only a tensile load or pull out load.
How do you do a tensile load test
