Please give your comments below.
Nice scientific explanation. Thank you sir.
I never attend this kind of lecture very very deep and good lecture thankyou sir
Just Amazing 🤩😍 Sir, Very Good Explanation Sir.
Good morning! I could not attend the live session yesterday. Just now listened to it. It was an Excellent Session. I appreciate the same.

Very nice explainatory lecture Sir.Thanks Sir...
Very nicely explained Sir.
Amazing sir, thanks!🙏
Sir
Your class is excellent.Thank you so much.
I have one doubt..
I have 3 samples of cube and i got the compressive strength of each specimen greater than 15 % of the avg value of each sample
Is the test result is acceptable or not?
I think the word 'Fail' should not be used, rather use 'Fall"
Namaste sir
21 mpa strength of 3 individuals is pass as avg. Is 25 and 25 *15%=3.75 and 25-3.75=21.25 which is higher then 21 so it is pass
But 25 *15%=3.75
25+3.75=28.75 and 29 is higher then 28.75 so it is fail
Please correct if I'm wrong
Sir please take more lecture. 🙏
Well explained sir hatsoff
Thanks - which topics would you like me to cover in the next episodes
Sir 1.durability and tests for durability
2.optimization of concrete mix
3. Importance of particle packing on concrete strength
Sir I am your old student and a big fan of you the way you explain it will remain in our memory for long time 🙌
Yes of course Mr Mohammad
We will take up these topics
Join me in our 3 days masterclass
Sir registered but didn’t receive confirmation email from u r side
Dear sir please make a video on cube strength acceptance criteria..
It should be Fck+0.825 for below m20 grade Concrete and above m20 is Fck+0.825*SD
As per is 456:2000
In a video with example it would be better to understand
Sir what is 1.65 for SD??
Can you please explain in English
