Concrete Core Test | Concrete Core Cutting | Concrete Core Capping | Concrete Core Test Machine :
In Concrete core test concrete cores are usually cut using the rotary cutting tool with diamond bits known as concrete core test machine. The cores are visually inspected for giving specific attention towards compaction of concrete that means air void visualisation, distribution of aggregate and presence of steel, etc.
The concrete core should then be soaked in water, capped with molten sulphur to make its ends plane, parallel and at the right angle. It is then tested in compression testing machine in a moist condition.

Very helpful

[@abdullahsulaiman1909]

Thank for this helpful vedio.
I have one question if you allow me.
What is the type of used epoxy for capping.

[@shivamshukla9256]

sir is it possible that my 70mm core test fails bt passes in all several ndt test ?

[@MohitSharma-ok3gp]

Sir plz tell me how to use sulphur for capping and which type of sulphure to be sued and if we can use cement then what is the procedure to make a paste of cement

[@mikejb2009a]

Good video but too many safety violations. No fall restraint, no safety glasses, I also think they should have been wearing cut-resistant gloves. Improper electrical connection to power supply notice he inserts wires from the drill into a socket. The drill should have had a proper plug.

[@hexontamang9594]

why curing not done before compression test, is code clearly suggest to cure before test

[@raviiee271183]

hello Dr. Chirag, how much of trimming of the core length which has been brought from the site is allowed to prepare a core for test. Eg if i bought a core of 230mm length, can i trim it to 100mm while making core specimen for crushing.

[@DrChiragNPatel]

Requirements of Concrete Core Height is 2 times its Dia. atleast.

[@raviiee271183]

@@DrChiragNPatel thank you. Is it okay if length and diameter are kept same to test the core sample..

[@RSRATHI2008]

For capping of core material use sulfar or other capping material ,not required capping tool ? please suggest , we use blue colour plastic instead of vertical capping tool , can we use bar ldetector

[@DrChiragNPatel]

No tool required.

[@DrChiragNPatel]

You can use if you have but we concern with performance only.

[@alijavaid8724]

Will result vary if capping material changed?

[@buddygmail]

What will happen to main structure from where the core was extracted, it will have cut reinforcemnt too. So longitudal reinforcement cut at that location. which will damge the life of structure and reduce the strength........ so core cutting is damaging

[@DrChiragNPatel]

You are right. But care is required to take that the core has been taken from the place where main bars are not cut. Also if possible no bar will be distracted.

[@RSRATHI2008]

what is the material use for capping ?

[@DrChiragNPatel]

Sulfer or epoxy but with strength higher than parent concerete

सर जी नमस्कार
कोर कैपीग में सल्फर के आलाव कोई और मिलाना है जो ये लिकिवट हो जाए
कृपया बताईये ये लिक्वेट कैसे तैयार करे
आपकी अति कृपा होगी

[@vimleshranjan9769]

Very useful information, but unsafe practice by operative, using loader as working platform and not wearing any fall protection. Hope you understand

[@DrChiragNPatel]

Yes. I understand it. But it's the time-bound solution of unavailability of stuff. Like your reply. Thanks for watching. Keep Watching.

[@hendryfermadi868]

@@DrChiragNPatel please have more concern on safety. its a high risk work you know.

[@chakradhar432]

Why liquid poured core concrete with explaination

[@DrChiragNPatel]

I think you talk about water supply provided while cutting the core. It is required to reduce the heating between concrete and drill bit. Water will lubricate the friction surface properly which make ease for the cutting without failure of drill bit.

[@Blogcompany_New]

Sir, what is the material used for capping

[@bpani14]

sulphur
