For 56 cub.mtr concrete, no of samples to be tested will be 4 only but not 5, because beyond 50 cub.mtr, it is one sample for every 50 cub.mtr additional...beyond 50, it is just 6 which is less than 50 hence additional sample is nil.
On time 30:53 jo ki second condition hai usme agar total mean (i.e. Fck+4) 29MPa se bada ya barabar aa gaya to kya krenge jabki isse just pehle wali condition me hmara 1 SAMPLE fail ho chuka hai ( that was 22 which was coming less than 'Fck-2' ). Tab kya conclusion hoga. Ye bata diya to my confusion will be clear. Kyun ki aapne jab 29 se kam aaya hai wo wali condition sirf discuss ki hai ke hum poora lot reject kar sakte hain esi condition me lekin main uske invert ho gaya to kya hoga ye janna chahta hun.
Between Individual Test results & Mean of the group of 4 Non-Over lapping consecutive Test results of samples, which one to be considered. whether it should satisfy both
Sir please clarify if one of the individual result fails then whole of the concrete loat is to be rejected. Or is there any provision to accept some part of loat a reject other.
Thanks for explaining the concept beautifully I want to know the usage of standard deviations( that we calculate using the sample data) in acceptance criteria. Thanks
Sir , but as per amendment no.1 June 2001 , for clause 15.3 they substituted specimens in place of samples ,what does it signifies whether 1 cube or still 3 cubes please clarify. Also they have substituted IS 9013 in place of IS 9103. PLEASE reply
Sir, Kindly specifically provide information of testing of concrete in PILE Foundation and methods/procedures of extraction of concrete cores in piles. Reply or videos. Its urgent.
Sir if my concrete sample acceptance not meet as per IS CODE after 28 days ..then how can i manage constucted work done before 28 days from this lot at site..
If 4 sample are taken and they are pass in mean strength criterion but one sample fails in individual test criterion In above case whole concrete shall be considered fail or only that portion of concrete for which sample is fail.
If no of samples are 6 How will you make group? Initially it is first four But what will be of remaining two sample Can I take group of sample 3,4,5,6 .If it is possible then it will be overlapping Please suggest
Sir 5m3 ka slab cast mkna hai matlab 1 sample tesr krna padega... Sample ka cube hum cast krte samy fill krte hai.. ar uska test to hub 28daya k bad krte hai....tab tak slab ki full strength a gai hogi..agar sample wrong aya to kya krna ...jo slab cast krdiya uska....
Agar acceptance criteria me fail ho jata hai to us batch ya shift ki concrete jahan use hui hogi Structure me wahan non destructive testing like core test has to be done agar usme fail hota hai then Structure/ component has to be dismantled and rejected and reconcreting has to be done
What is the relevance of target mean strength of concrete with the site test results? Should the compressive strength of concrete after 28 days be greater than the target mean strength? For example : Target mean strength of M25 grade concrete is 31.6N/mm2 (25+1.65*4) and Compressive strength of sample is 30N/mm2 at site. Is this sample is acceptable?
Mix design is based on target mean strength . Concrete is accepted or rejected based on acceptance criteria explained video not based on what you are saying...
If there are 2 samples in which one passes the validity test and the other one fails then what will we do sir? Will the whole lot be rejected due to mere invalidity of single sample?
آپ نے بہت ہی سندر انداز میں اس رد اور قبول کے مسلے کو واضح کیا۔ شکریہ جناب
This is One of the important & confusing topic....now crystal clear sir 🙏🙏🙏
Thanks rajesh
चरण वंदन गुरुजी।
आपकी प्रत्येक पंक्ति एक दम सटीक अर्थ व्यक्त करती है।
धन्यवाद।।
Thank u sir
This is very useful all of us.
Really awesome

Bahut khoob sir . 🙏. Thanks
Sir if the number of samples are 5 or 6 or 7 then how we take constructive non overlapping sample for 5,6,7 no. Of sample?
On time 30:53 jo ki second condition hai usme agar total mean (i.e. Fck+4) 29MPa se bada ya barabar aa gaya to kya krenge jabki isse just pehle wali condition me hmara 1 SAMPLE fail ho chuka hai ( that was 22 which was coming less than 'Fck-2' ). Tab kya conclusion hoga.

I appreciate your work..
Excellent information sir
Pls make a one video of MS 2
Between Individual Test results & Mean of the group of 4 Non-Over lapping consecutive Test results of samples, which one to be considered. whether it should satisfy both
Both have to be checked and complied for acceptance criteria
Hai sir, maximum permissible and minimum limits 7days Compressive strength Cube test any codal provisons and also grout ?
have u posted videos related to IS 516 and IS 1199 for the latest updated version? sir .
Sir please clarify if one of the individual result fails then whole of the concrete loat is to be rejected. Or is there any provision to accept some part of loat a reject other.
Thanks for explaining the concept beautifully
I want to know the usage of standard deviations( that we calculate using the sample data) in acceptance criteria.
Thanks
It will be also utilised for mix design as per IS 10262 and also deciding the target mean strength
thank you so much sir
Best conceptual video
Thanks so much sir
Iska next part kb aayega sir?
Excellent sir 👌👌 nicely explained

PLEASE reply
What I told is latest amendment so don't get confuse ..
Sir, Kindly specifically provide information of testing of concrete in PILE Foundation and methods/procedures of extraction of concrete cores in piles. Reply or videos. Its urgent.
33:47
What about 2 left out samples. Will it be considered as Group 3 with 2 sample only or it will be not considered for testing?
Make a video Who to calculate the standard deviation
Ok
Standard deviation pr video bnao bhai
Excellent .
to test cubes after 14days how many samples required? same as that after 28 days or may be something?
Sir if my concrete sample acceptance not meet as per IS CODE after 28 days ..then how can i manage constucted work done before 28 days from this lot at site..
Very well explained !
Thanks dear
If 4 sample are taken and they are pass in mean strength criterion but one sample fails in individual test criterion
In above case whole concrete shall be considered fail or only that portion of concrete for which sample is fail.
Is concrete is pass or fail when individual test report of specimen is more than 25percent
Is concrete is acceptable or not please guide me
if sample no are 7 then how to calculte accept test
If no of samples are 6
How will you make group?
Initially it is first four
But what will be of remaining two sample
Can I take group of sample 3,4,5,6 .If it is possible then it will be overlapping
Please suggest
I think it will depend on the concrete quantity that is being poured
Thanks sir

Will the whole lot be rejected due to mere invalidity of single sample?
Only invalid sample to be rejected and not considered for compressive strength testing to check for acceptance criteria.
Where have to use Fck+4 and where Fck+3?
Its already explained
Amendment ki video sir?
Amendment for these provisions already included
Cube nahi set of sample hai
