Methodology of cement concrete core test|concrete core test procedure as per ASTM C42

What to do with calculated and noted steel ?? What if reinforcement there in core ? Please explain..

[@HIGHWAYENGINEERING]

It is reported that the presence of transverse steel causes a 5 to 15% reduction in compressive strength of core. The effect of embedded steel is higher on stronger concrete and as its location moves away from ends, i.e. towards the middle. However presence of steel parallel to the axis of the core is not desirable.also we should test rebound hammer test.

Correction factore…..amazing video…superrr

[@HIGHWAYENGINEERING]

Thank you 🙂

[@ijazarif245]

ap ki video bht achi lgi thanks

[@success555]

Nice presentation.

[@rgrrsgggf]

very nice video thanks

[@ImranKhan-mn1bs]

Very useful video.

[@HIGHWAYENGINEERING]

Kindly share with your friends

[@ImranKhan-mn1bs]

@@HIGHWAYENGINEERING why not. I'm already share every video with all friends.

For testing in CTM, is it compulsory for core to be level/smooth in both face i.e top and bottom?? Usually cores are levelled at top not at bottom..

[@HIGHWAYENGINEERING]

yes its compulsory

[@BERNARDGLENNESPINOZA]

Can we still use 50mm dia. core for column with closed ties where 100mm dia. is not feasible?

[@HIGHWAYENGINEERING]

Yes

[@prabeshmanandhar6095]

What about the twmperature correction factor on cylindrical sample obtained from core cutting??

[@khaledeajal7651]

Tanks for lessons

[@prabeshmanandhar6095]

B) calculation point no. 2: Can you please provide supporting document which mentions the strength should be 75% for single core??

Agar concrete mai PSC POST Tensioning Girder hai aur wo 15 mtr Height se falling huva hai to core result kitna trustabel hoga?

[@rahulpatil-hx1pu]

Sir Please Upload the vedio of complete calculations and result for better understanding

[@HIGHWAYENGINEERING]

already uploaded brother

Very Nice

Does L is before capping or after capping for L/D ratio

[@HIGHWAYENGINEERING]

After capping

[@michoudhary6450]

why this method is not applicable to cores from Shotcrete?

[@ahad6096]

Can you tell me which standard apply for shortcrete cores plz

[@tilottamasahoo9790]

Sir F ka formula kaha se lai? Please bataiye

[@itsankit27]

What will do if L/D ration is between 1.75 to 1.90?

[@qureshiatif6042]

No need to apply correction factor, note the comp. strength as it is.

[@MrTeacher-9000]

Hi

[@hy89794gmailcom]

Pehle aap ne kha ratio 1.75 se kam h to koi correction nhi karna Fir kha 1.75 h to correction factor lagega
