Thanks. I can't take him seriously now lol.

[@jahmeenlopez3226]

Lol

[@Elmer23able]

Wow thanks. I learn a lot from this video. I'm a civil engineering student and I'm solving atterberg limits in my soil mechanics. Now with dis video i know how its done in actual. We dont have lab. 😭

[@andyhec]

Great video. I have a casagrande device and wanted to know more about it. Your video concisely gave me the thorough answer.

[@youwilllaugh3136]

Sir i would like to say this video was well done and professionally organized very good job

[@manarbarghouthi4506]

thank you! i was about to split my papers !! but now everything is easier .. i could'nt understand this test without watching it :)

[@eugenesandra2841]

Am grateful this video has help me know how the run the Atterberg Limit test

[@areeb9781]

Thanks sheldon cooper, you save the day !

[@TheSterlingArcher16]

I find it incredible that 200k people have watched a video about a dirt test.

[@beardybeardy9176]

Professors across many universities and students who are currently enrolled or recently graduated from an engineering program typically do soils testing in the first couple years of being hired. We learn this in college but once your career starts we have to watch videos like these to review how to properly do these tests. The infrastructure you know and use are constructed from these "dirt" tests. We have to determine the properties of the soil and then we can determine if the proposed structure or roadway is feasible off that soil sample. They are the foundation of any man made structure before the actual foundation is poured.

[@mk4gli680]

Its not dirt, its SOIL!!

[@andrewlecheminant1079]

I think this was a good overview of how these tests are done, but there were many errors in regard to what the ASTM requires.

Wowo that's grateful for my engineering test in korea. Also, the man performing this test is somebody , hansome

[@faust8569]

Thank for for demonstration and explanation of LLT and Plastic👍👍

[@frankhunter244]

I think you need to let the material cure for 16 hours in a sealed container after you add distilled water to the dry material and before you run your test.

[@twistessense6143]

if it's any kind of clay. if it's Sandy silt I believe it's 4 hrs

[@mohammadalkaraki9696]

you are awesome clear and helpful information

[@MrScott6183]

never hold the base when counting blows....thats a no no

[@Dripster76]

Why is that?

[@raes3369]

@@Dripster76 Because the vibration the cup causes on the base is one of the things that makes your soil closure happen. If you're holding the base, that won't happen as accurately. Also because if you hold the base during the audit of your lab, they will yell at you!

[@highwayguidecivilwalk]

Very informative video Thanks for your kind valuable video for us ..... 🙏👌

[@nz1229]

I was always wondering why we just don't weigh out multiple samples with various amounts of moisture content before doing the liquid limit. Is it because soil will loose water (and therefore have different moisture content from where it started from) when we roll it? If so, it seems like a delicate operation because how can you know if a particular subspace of the sample is truly homogenous?

[@karenanticona8561]

justo me pidieron ver este video de mi clase y me enamoré

[@opinionsmayvary5009]

Why would you use bentonite if the soil in said test is non plastic?

[@yahyafarooq8706]

what is oven temperature? and 40 no.sieve size passing dry method or wet method use?

[@richardpaige8758]

Thanks, good video for a refresher too

[@danielmwanyangapo5485]

Give a video description please .... Very nice though...

[@kentvillocillo2896]

what's next after having the data? how do you to interpolate it?

[@chrome3615]

Reall??? You just failed WAQTC! You're not supposed to hold the apparatus during the blows

[@luisantonioenriqueztellez9228]

en el LL el llenado de la copa debe de ser a 3/4 de su capacidad, la ranura debe ser en linea recta y el golpeteo debe ser constante ya que eso afectara al graficar, y el PL esta muy húmedo aun, se puede ver a simple vista. saludos

[@hapetman1]

Not to be nitpicking. but they are a lot of things I notice that are not precise. If this way is done on AMRL assessment inspection, for sure it would get tremendous non-conformity (it means not conforming to ASTM or AASHTO).

[@MrSecondcircle]

You explained it okay well sorta. Think you were a little confused (25-35, 20-30,15-25 start low moisture end high moisture) but that's okay almost didn't catch that was amazed at your uncanny ability to see the middle of the sweet spot from the top of the bowl to calibrate it and you called that a patt then grooved it. Was even more amazed when you started to run the test. But really good thing you had that metal rod for the pl it would take a engineer to pull out the hinge pin holding the cup to the LL device and use it. LOL our future builders.

[@twistessense6143]

hahaha that fuckin pin fuck engineers lol. totally kidding kinda

[@kswcvl5574]

were you now😊

[@outsiderinhtown]

thank you guys!

[@aljosatimarac4867]

Great job, thanks for this!

[@bryanhiebert1]

Hey the way you calibrated your drop height isn't correct. You should measure to midway through the wear spot on the cup, not from the wear spot on the base. The cup doesn't drop perfectly vertically so if you set it to the wear spot on the base, your drop height will be about 13mm instead of 10mm. That difference will skew your results significantly.

[@omarxawneh]

this was helpful, thanks man, great work :D

[@murancematthew2328]

Ehhh. Need to asked. Do this test have count drips?

[@r.e9101]

Thanks for make this video, I couldn't do this practice, because COVID-19, but this video is helpful.

[@sujatadesai3878]

Tq ...The video helps me alot during studies...tq u so much...

[@xaliqhuseynov9816]

Someone can explain me how we can use it on construction of building or road?or in commonly how this test can be useful in normal life?why we need this test?

[@Noeman2009]

It has practical purposes. If the plasticity index is high, it tends to have high clay content and expansive soil. Expansive soil is very dangerous to any man made structure. Slab on ground can pop up or expand because expansive force of the soil. Because of Its expansive nature, the change of volume of soil because of change of water content will be greater than non expansive soil.

[@thinukamanawadu3158]

what type of soil get for the atterberg limit test?? undisturbed or disturbed soil sample

[@waisk6191]

definitely, that is disturb soil

[@kiyammuntoh5760]

Wow what I just learned today in school

[@rosarae]

Well done video, up until he ran the test. I'm going to make my own training videos and sell them nation wide. I am so sick of watching other labs butcher these tests. Are we the only lab to perform soils and concrete tests with some care and common sense? Anyone else feel the same?

[@patrickcameron2266]

Considering he forgot the time limits stated in the ASTM on performing the PL. You have 2 minutes to roll that thread down to size and you have to maintain a steady and constant pressure on the thread. I perform this test a lot and you have to follow the standard precisely or it will effect the results. And I run this and many other tests for AMRL and CCRL accreditation for my lab.

[@rosarae]

Patrick Cameron To name just but a few things he did terribly. We recently received a ding from CCRL on sp. gr. of a concrete cylinder ( proficiency samples) for correctly calculating the volume of the stripped cylinders. Had we used the theoretical volume of the mold, (4.000" X 8.000") we would of had been dead center of the national average with our weights. The hardest decisions with testing some of these proficiency samples is determining as to run the tests as per code, or guessing how the other 90% of the idiots in the country are going to perform them incorrectly so we can fit in! Nothing more aggravating than being punished for running a test accurately!

[@anbeebe471]

Did you mean rotations per minute? Rpm instead of revolutions per minute? 😄

looks like the defination of plastic limit is wrong......it is the water content at which the soil starts behaving as a semi solid. i.e from brittle to plastic state.
