This is most needed and unique idea of podcast, make it continue with such real knowledge.

Thank you !

Nice explanation after 4 years of experience I don't know the things sir is talking about

India's first podcast on civil

Thanks for your valuable input. The short answer is the coefficient of variation (COV) we have to look at & not merely a standard deviations as the grades are different from each other. As we all know that SD is measured from the mean value and when we compare two SD, at that position the mean value should be equal to the same for those two cases. In that case higher SD means higher variations. When mean value differs from them as in case of M 15 & M65, in that case SD merely of that two gardes does not have any significance. In that case, we have to find out the percentage variation of two standard deviations wrt mean value as they are different from each other what we call coefficient of variation (COV) For an example, for M15 and M65 grade, targeted strength are considered as 20.8 & 75 respectively. And their SD as declared by you as 3 03 and 4.86 respectively. Now while calculating COV of these two grade, we find as 14.56% and 6.48% for M15 and M65 respectively. Therefore, though SD for M65 as 4.86 is higher than 3.03 of M15, still we will say the degree of QC in case of M65 is far better than M15. Concluding at the end higher SD does not always mean a lower degree of QC. We will have to see their mean value also. I did not get sufficient time to explain COV on that podcast as the event was limited specified time limit. That is why maybe if I am not wrong, this question has been raised.

Sir, you explained the design mix process very simple

Thanks Atul, my dear...❤

This KZread file is a good attempt to explain IS 10262 2019, by Shri Nirmalendu. As he had said, standard deviation depends upon quality control and lower SD means better control etc. Then the value of X in mix design calculation for target mean strength is given to increase with grade as X values for M15 and M65 are given to be 5 and 8 thereby standard deviations S work out to be 3.03 and 4.86 MPa respectively. If lower SD means more control and vice versa, then, this calculation shows or it means - higher grades of Concretes can have lower quality control!!! This is a fallacy. Then, how to explain or justify higher X for for higher fck ie., higher concrete strengths. Why higher grades of Concretes are expected to have higher SDs? Shri Nirmalendu can give his comment on this.
