Thank you for the video, it was very useful to a brazilian civil engineering in formation, at UFPR (Universidade Federal do Paraná). Waiting more contents!
This you tube channel is increadible.... I will probably stay at Sir's home if I was a physical class student of him... I'm really glad that I could be at least an online student of heam
Thank you Sir for your valuable and crystal clear explanation using innovative and interesting animation. It is really great... 👏😄👏 KEEP UP THE GOOD WORK !!!🍰🥧👍
Little correction As per the ASTM standard, the contact length should be 13mm (0.5 in) ASTM Designation: D4318 − 17: Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of Soils, page 9 12.4 Lift and drop the cup by turning the crank at a rate of 1.9 to 2.1 drops per second until the two halves of the soil pat come in contact at the bottom of the groove along a distance of 13 mm (1⁄2 in.). See Fig. 7 and Fig. 8. The base of the machine shall not be held with the hand, or hands, while the crank is turned. NOTE 10-Use of a scale is recommended to verify that the groove has closed 13 mm (1⁄2 in.).
hello, can you help me to solve this question ? liquid limit can be determined using the ASTM method by plotting the moisture content versus the corresponding number of blows on semilogarithmic graph. Liquid limit can be also determined by the fall cone test by plotting the moisture content versus the corresponding cone penetration on semilogarithmic graph. How do these two relationships look like? And why? Thank you.
Sir which is correct ● When a groave of 2mm is filled with 25 no of blows , then that water content is called liquid limit . OR ● When a groave of 12mm is filled with 25 no of blows , then that water content is called liquid limit .
As example 13 mm meet by 5 blow - means more water in the sample - thin sample - less shear strength. 13 mm meet by 50 blows - means less water in the sample - thick sample - more shear strength. 3 points 1. How much distance meet 2. Water content 3. No of blow To establish relationships between any two, take the 3rd one as constant.
Assalamo alaikum! I have two questions regarding this vedio can any body help me? #1: why we use No 40 sieve not any other? If answer is to get finer fraction then why not No 200 sieve is used? #2 why 25 No of blows is fixed to get the liquid limit value from semilograthmic graph?
Thats a good question, did you get a answer? i was thinking that was his experimental method example. I think you can use any sieve but the finer the easier to close the soil. I think you can as much blows as needed but it needs to be consistent in each test.
. If the material of the base of the Casagrande liquid limit device on which the cup containing soil paste drops is softer than the standard hard rubber,thenA.the liquid limit of soil always increasesB.the liquid limit of soil always decreasesC.the liquid limit of soil may increaseD.the liquid limit of soil may decrease ANY ONE CAN PLEASE EXPLAIN THIS??
Liquid limit means that particular water content when 13mm (0.5 inch) meet under exact 25 blows. Now when standard hard rubber used: water content is X% & meet 13 mm & blow = 25. Now softer rubber used: Meet should be 13 mm & blow is also 25, to do that flowability of the soil must be increased as rubber base is softer, so liquid limit will be more than X%. We can say under 25 blow, to meet 13 mm using softer rubber base more thin sample is required. So Option A is correct.
This channel is gold. deserves much recognition
I just got recognition from you.
Thank you.

The way you explaining the concept with the diagram is very nice . Your way you explaining any concept is unique
If the number of blows in a Casagrande apparatus is more than the liquid limit of the soil will be more or less?
No words to say,thank you sir 🙏🙏🙏

Best video on internet on this topic ❤
Thank you Sir for your valuable and crystal clear explanation using innovative and interesting animation. It is really great... 👏😄👏 KEEP UP THE GOOD WORK !!!🍰🥧👍
💯👍
Very nice explation with animation in each procedure step
Super video. Great animation. Clear explanation. Well done!
Thank you sir ! Your video helped me lot to understand that properties of fine grained soil !!

Your videos are so knowledgeable and amazing!!!! Please make more videos related to engineering
What a conceptual animation prepared for all students thanks Sir... great methodology and working MWA LATIF
Thank You Sir
Very well done video. Very much appreciated.
U are doing great work sir
Much appreciated
thank you sir for your kind efforts!!👏👏
Best class
This was awesome!
No words.. Super explanation.. 👍
Most useful to me.
thank you so much....just amazing video🥳🙏
Best channel... Please make more videos on civil
Amazing animation superrrb ❤❤❤❤
Best Lecture 👍
amazing explanation with great animations.
Bro you are awesome😍🖤🖤
thank u so much it's so helpful for my exams
Thank you ❤
Nice way to explain the things 👍
wow. this is superb video👍👍
Really very good work, very informative and sequencial
thanks for efforts sir 🙏
Really helpful ❤
OHH BHAII op 🔥🔥🔥🔥🔥 acha Montage h 🔥🔥🔥
Sir please upload foundation engg also ..your animation is superrr..more video from soil
It's amazing Sir , ❤️❤️

Very good educational video.thanks for educating engineers.
Good job 👍
Bahut acha sikha rahe hai app😊😊😊😊😊😊
Thank you so much...
Thank you !!
Sir g waiting for your videos
Your have amazing skill to define
The best representation 👍👍👍👍
आप बहुत अछा काम कर रहे है
मैं आपसे प्रार्थना करुगा के और सारे वीडियोस अपलोड कर

Your are doing a great job
Hello.Mr.could you explain what's mean of the 12mm on the apparatus that you drawing？
Very nice video..
Thanks a lot
It made me clear.
Informative 👍
Upload more please.
Is it flat flow curve has relatively more shear strength compared to steep flow curve?
very helpful

Thank you, sir, for such an informative video.
Which software you are using for this
excellent Video sir
Thanks for the information sir
Good exaplanation
Thanks for vid.
Useful
Thnk you sir im from Malaysia
Thanks sir
lovely video!!! how did you do this animation?? I need to do something similar for a presentation!
What if I add 18 mL water and when I use casa grande, for 50 blow the soil doesnt meet in the middle
Nice video
Love you sir thank you
Please upload more videos sir... 🙏🙏🙏🙏🙏
Why plotted in log scale???
BAWASEER 🔥🔥
Sir,What happens to Liquid limit when clay +lime is taken?
U should upload video on short interval to engage audience
Sir which is correct
● When a groave of 2mm is filled with 25 no of blows , then that water content is called liquid limit .
OR
● When a groave of 12mm is filled with 25 no of blows , then that water content is called liquid limit .
First one
generally how much percentage of water content for 25 blows
Please upload more video
Sir how water content is high at less no of blows
As example
13 mm meet by 5 blow - means more water in the sample - thin sample - less shear strength.
13 mm meet by 50 blows - means less water in the sample - thick sample - more shear strength.
3 points
1. How much distance meet
2. Water content
3. No of blow
To establish relationships between any two, take the 3rd one as constant.
Shoutout sayo❤️
Bro please upload more videos

Liquid limit means that particular water content when 13mm (0.5 inch) meet under exact 25 blows.
Now when standard hard rubber used:
water content is X% & meet 13 mm & blow = 25.
Now softer rubber used:
Meet should be 13 mm & blow is also 25,
to do that flowability of the soil must be increased as rubber base is softer, so liquid limit will be more than X%.
We can say under 25 blow, to meet 13 mm using softer rubber base more thin sample is required.
So
Option A is correct.
The flat tool this's a astm tool ,
not curved tool.
Please verfiy that .
I learned that the curved is called the Casagrande tool
Liquid limit less than 50 % a range 15 to 35 drops
