can u upload excel for calculation, and show again zero correction

Thank you 🙂

Thank you 🙂 Watched all your Lab-Videos

Thanks

Thabk you

way more chill than my current instructor. great vid.

very cool

What an incredible channel, I'm reviewing basic stuff covered in soils mechanics and I think your videos are great.

Great video, I'm recently getting into soils mechanic and your content proved useful. Keep it up!

Can you please tell us the full # of times where measurements are taken?

what type of sand was used during the calibration?

Really helpful for my thesis Thankyou

Hey Ryan. Great job on the video. There are a few things I wanted to point out that are potential issues. When determining the Cone correction factor you need to do this procedure over the base plate, as you also need to account for the sand that is between the thickness of your base plate and cone. Second thing is you cannot manipulate, vibrate. rattle, or move in any way or you will affect the result of your density. Thirdly when you remove the soil from the test hole it needs to be placed in a moisture proof tared container so that you do not lose moisture and makes it easier for determining the mass for figuring out the wet density. Also worth mentioning is having holes drilled through your base plate so you can pin it to the ground so it will not move on you while excavating the hole. you may want to look into the proper procedure for filling the cone/container. Hope this helps and clears up and issues with determining the density of in place soils using sand cone method.

Thank you for this video.

Watching to understand Newmark's influence chart yay idk how to do my hw

Sir you are amazing.

Please do a full CBR test next! there is literally not a single video of ASTM D1883 anywhere on the internet that is both in english and actually uses the standard.

The pycnometer is similar to a flask that is used to measure exactly volumes of liquids, indicated on the surface by a gauging line. I don't know how to say it in English, but in Spanish I know it as "Matraz Aforado"

I am just wondering, as opposed to the sand cone test, or nuclear density, or the balloon/water test, why not just put a thin bin-liner in the hole (very loosely put in), and pour water until the meniscus of the water is just touching the top of the hole? You could then just pull out the plastic bag, measure the volume of water, and that's that. I can't imagine it would be any less accurate doing it that way than a sand cone test? Could you elaborate please Ryan. I can imagine that air pockets might form, but if digging out to ~4inches was done carefully to make a nice bowl shape, surely this would be very accurate at calculating the volume of the hole (+/- a fraction of a percent error) with no need for any equipment other than a thin bin liner, a flat edge (so it touched the water meniscus) and some scales. Thank you

Very good videos, thank you for your work. Just a suggestion though: maybe show also how to work the data after the test, for those who are not your students. I know that's probably not your goal audience but it would be nice to see the rest of the analysis.

I'm from Cambodia I'd like to say "Thank you so much" for sharing this lab experiment.

I appericiate your effort to educate viewers. You are using British Standard grooving tool and according to BS-1377 Part 2, you should add incremental amount of water between each test. Adding dry soil makes soil puddy to have dry crust, so homogeneous property that we are looking for isn't achieving like the standards suggesting us. There is a lot of nitpicky details in standards' documents to making perfect liquid limit test.

you can use other sizes like 100 mm or have to 500 mm?

I've been looking for better ways of mixing soil for this test in our lab and ran across this video. Very educational but I noted 2 things that hopefully will help students. The water you are using should be distilled or demineralized and also when creating the valley in the Casa Grande I usually hold down the brass bowl to not allow the final second to pull up the bowl and accidently slam on the base. Thanks for making these videos.

Hi is that the results of the specific gravity that show in the screen, is that the specific gravity or not? Because in my calculations different from yours

If you're taking suggestions, could you do a video on classification of soils? ASTM D2487

Excellent

Hi I am running a small plant and interested in a simple way to measure the density of my slurry

Love your videos. Any videos on triaxial shear test and direct shear tests? You make them so easy to understand

Thank you very much Sir! It was very helpful for me.

very helpfull video ,keep doing brother ,thanks bro

👍🏻

Good teacher 👌🏻

Excellent sir i need your WhatsApp no

Sir can I ask how to get the average flow?

It was amazing ❤️❤️❤️👌🏼👌🏼👌🏼

Amazing

Please can you make a video on Menard Pressuremeter Test on soil? By doing so, you will do a great favor. Thanks for your videos.

thankuhh sir❤

Hi Sir, Do you have a video that shows measurement of Ksat using Eijkelkamp's Lab Permeameter? Or can you please share a link of that video that you are aware of ? Thank you

Thank you Sir really helpful especially this time.
