thankyou sir as a learner i love your effort and what a video you are providing love you sir god bless you and please carry on these efforts again thanks a lot 😍😍😍😍😍😍😍😍😍😍
Bahut ache se explain Karte hai ...this video is very useful to every civil engineering student....because theory is not important but practice is most important..... Thanks a lot 🙏 .....
Sir, would you mind telling me the most important test on coarse agreggate that will effect on mix design, I know specify gravity, water absorption, and sieve test are important. But what is the most important for mix design? Thank you in advance
The Flakiness and Elongation Index tests for aggregates of 10mm and 20mm sizes are conducted separately as per the relevant IS code guidelines. This is because the tests involve sieving the aggregates through specific size ranges and checking each size fraction individually to determine their respective indices. Code Reference: 1. Flakiness Index: IS 2386 (Part I): 1963 It specifies the method for determining the flakiness index of aggregates using a flakiness gauge. 2. Elongation Index: IS 2386 (Part I): 1963 It also outlines the method for determining the elongation index using an elongation gauge. Testing Guidelines: For Flakiness Index, aggregates are passed through the respective sieves and their flakiness is measured for each fraction. For Elongation Index, aggregates retained on various sieves are used to measure elongation. Separate tests are conducted for different sizes (10mm and 20mm) because the sieves and gauges used depend on the aggregate size fraction. Practical Note for Design Mix: When preparing a concrete design mix, the results of both tests for each aggregate size are used individually. They help ensure compliance with quality standards and the desired properties of the design mix.
The permissible limits for flakiness index and elongation index of aggregates are specified in IS 2386 (Part 1): 1963. Here's a summary: Flakiness Index Maximum limit: For road works: 25% (as per MORTH specifications). For high-quality concrete: 15% to 25%, depending on the application. Elongation Index Maximum limit: 30% (common for road and construction aggregates). The combined flakiness and elongation indices of aggregates should typically not exceed 30-35% for most construction purposes.
Very good video.your style of giving practical knowledge is praiseworthy.
Thanks for your valuable comments 🙏🙏🙏
One of the Best Videos about flakiness and Elongation Index ❤Thank you so much for the whole team❤
Thanks 👍
I am quality engineer.. impressed by your efforts..

Thank u so much for this ❤
Good job
very neat explanation
Very super 👌👌 video
Explained very well 👏
thank you good information
Great lecture❤
Thank you! 🙂
Very good video👍
well described.👍
Good 👍
Thank you sir!!!
sir can you please make a vedio of CBR test if you can. it will be very helpfull
Sir, would you mind telling me the most important test on coarse agreggate that will effect on mix design, I know specify gravity, water absorption, and sieve test are important. But what is the most important for mix design? Thank you in advance
Flakiness and elongation index
Super.... Bhai isme amendment no. 3 follow kiye ho jya
nice explanation ❤

Is falkiness abd elongation done separately forv10mm and 20mm
The Flakiness and Elongation Index tests for aggregates of 10mm and 20mm sizes are conducted separately as per the relevant IS code guidelines. This is because the tests involve sieving the aggregates through specific size ranges and checking each size fraction individually to determine their respective indices.
Code Reference:
1. Flakiness Index: IS 2386 (Part I): 1963
It specifies the method for determining the flakiness index of aggregates using a flakiness gauge.
2. Elongation Index: IS 2386 (Part I): 1963
It also outlines the method for determining the elongation index using an elongation gauge.
Testing Guidelines:
For Flakiness Index, aggregates are passed through the respective sieves and their flakiness is measured for each fraction.
For Elongation Index, aggregates retained on various sieves are used to measure elongation.
Separate tests are conducted for different sizes (10mm and 20mm) because the sieves and gauges used depend on the aggregate size fraction.
Practical Note for Design Mix:
When preparing a concrete design mix, the results of both tests for each aggregate size are used individually. They help ensure compliance with quality standards and the desired properties of the design mix.
Love from pakistan ❤
Please one video for los angeles machine full calculation
Minimum 200 pieces lete h na for every conductive sieve for flakiness n elongation test
Or ye flakiness ka individual 15% limit kis IS code m diya h. Combined to 40% hoti h but individual ka kis IS code m diya h. Plz reply
@@ershahnawaz220 combined 40% bhi kon se IS me hai??30% hi to hai
Sir naimbair d
@@neelpatel1333is per is 383 combined flaky and elongation should not be more than 40%
Can we perform this test for GRADE1 ,Grade 2
Good 👍👍👍👍👍
Great
thank u soo much sir
Most welcome
Nice.
I am Quality Engineer👍
Theek hai
Fdd calculation krna sikhye request
Good
Nice
Very nice
Weight of sampl???
Mujhe ye btaye ki kon sa IS code m ye dia hua h ki flakiness or elongation ki
Kitna percentage hona chahiye
Mujhe mila nahi
IS code 2386 part1.
The permissible limits for flakiness index and elongation index of aggregates are specified in IS 2386 (Part 1): 1963. Here's a summary:
Flakiness Index
Maximum limit:
For road works: 25% (as per MORTH specifications).
For high-quality concrete: 15% to 25%, depending on the application.
Elongation Index
Maximum limit:
30% (common for road and construction aggregates).
The combined flakiness and elongation indices of aggregates should typically not exceed 30-35% for most construction purposes.
Tq sir
If 25mm sieve pe retain ho Jaye
Thanks sir
Please reply did you followed amendment no. 3 of is 2386 part 1
What about 10mm course aggregate elongation index
Sir abhi me diploma kar raha hu muje qc engineer banana hai to kese ban pavunga
Mujhe. Falayki. Longest. Kafamu. Batye
10 evening me saam 😊
Add ko skip karne ka option on karo bhai.... pura concentration kharab hojata hai
Note: elongation index me flaky aggregate ko nahi lete like karo sab
Sir 1280 me se 250 jayega to 1030 bachega
Aapko pata hai elongation gauge update hui hai, ushme 31.5 - 25 bhi aayi hai
उल्टा कैलकुलेशन बताओ
Minimum 200 Pieces Hona Chahiye Sir
Video Banaye sir
Im lab technician sir
Aur sikho
Bro what is IS code ...........?
Is 2386
sir fresher
Send Testeeg keluletar
Wrong calculation
We have to calculate % passing of each friction
❤️❤️❤️💕💓
It shoukd be 200 pieces
Dono ko milakar 40% se upper Nahi Hona chahiye
4.75 ka nhi h
100 Nahi 200 tukde Lete hain
Why you are taking 100 pieces it is 200 pieces
Thik h 😂
కానీ సాలరీ చాలా తక్కువ
Sir what about 10mm?
Thank you Sir!
thank you so much sir🙏
Very good explanation
Good 👍
Thank you sir 🙏
Good
Thanks
Thank you sir
