Useful video

[@khanfahad93]

Thank you sir,🖐👍👍👍👍👍

[@lalitsharma2445]

Best wishes , sir , Nice

[@HIGHWAYENGINEERING]

Happy dussehra sir

[@prashantjha8395]

Slightly modified krne ke jarurat h aapko jb Aapka sample 4 ke ass pass hota h to aap fck+0.85standard deviations Or phir AVG cube strength ko check Kiya jata h es se agr AVG cube strength Jada h upper wale se to safe h or koi v individual cube strength Ka +- 15% variation se Jada nhi Hona chayia AVG strength se

[@HIGHWAYENGINEERING]

Ok sir i will do

[@taranjeetsingh3295]

Samajh Nahi pa Raha Hu kya kahna Chah rahe he. Pls clear kare

[@shivamvlogs1530]

Good 👍

[@gelpharma1pro]

sir, we did coring in concrete beam dia 68mm and length 136mm without capping for m30 grade what is the compression strength should be ?

[@kundanmodiya2]

Good yr rahul

[@ramswaroopmeena919]

Very nice sir DBM BC ke core minimum offset kya hai g

[@Akash-1238]

150 mq par 2 core katne hai morth ke konse kaha diye hai

[@SyedAli-uw8tw]

Kaisay 40 days ki cube strength nikalaygay

[@taranjeetsingh3295]

Sir cube strength me 28 days per cube ki Jo strength aayi he wo Lena he ya characteristic strength

[@prempande4574]

Agar core 2 saal baad liya jaye to bhi kya same acceptance criteria hoga ya different.. ?

[@dharamnishad7482]

Inice explained

[@SyedAli-uw8tw]

Sir I button ni mil raha h

[@taranjeetsingh3295]

DLC core Ka b same process he kya sir

[@HIGHWAYENGINEERING]

Yes, 100 mm dia cores

[@chitranjanthakur9301]

As per is 456:2000 clause 17.4.3 Concrete in the member represented by a core test shall be considered acceptable if the average equivalent cube strength of the cores is equal to at least 85percent of the cubestrength of the grade of concrete specified for the corresponding age and no individual core has a strengthless than 7S percent. That means required core strength is fck +(3*.85) not .85*fck

[@civiltechnicalslalitsharma54]

There is two criteria , One is depends upon acceptance criteria which is given in Is 456 And another one actual cube strength of that area from where core has been extracted

[@abhishekmahajan9409]

Sir jo corrrction factor me formula hai vo kaise aaya sir means 0.11 kaise aaya please reply sir please

[@user-ox8sf5eh3c]

As per IS 516 2018 code correction factor (F) = 0.11*(l/d)+0.78 ji.

[@NarendraPatel-nb1mq]

Excel sheet sir
