Make sure you release the proctor hammer at the very top! The person in this video is actually letting go half way down. You want the full force of the hammer in this test. Otherwise you won't achieve your true density.
No! Neither ASTM D698 or D1557 even mention such an action; Kalinski is wrong here. This test is to provide a very specific amount of energy to the soil, not replicate field methods. Scarifying the surface between lifts upsets the energy that has already been imparted to that volume of soil.
After compaction of third layer, the maximum allowable hight of compacted soil toward collar is 6 mm. This matter has mentioned is the D-698 but in this video it was more than at least 10 mm and this is wrong. Please share your ideas with me here if i wrong
Thank you for the video🙏....it would be more pleasant to watch it without music
Nice one! keep more videos on other test such as specific gravity, shear strengh, etc .They arev helpfull

I noticed that they weighted the samples first without the lid, and after drying with the lid.
Thanx for easier explanations with practical.🙏
Before placing each new layer, the surface of the previous layers is scratched in order to ensure a uniform distribution of the compaction effects. :)

Scott Merry ...exactly, I have done thousands of proctor tests
We are reading this in online class because of you ☺️☺️
Thanku very much for making our online class entertaining💕💕
As a geotechnician in Australia, you've made this test look MUCH harder than what it has to be. That compaction hammer is over engineered,
Why no be grateful for her effort? What have you don on RUclips to raise the prospects for the education for Geotehnical Engineers?
I know, idk why they're using a hammer that requires 2 people to use, I didn't even know such hammers existed.
@@ntrg3248ikr. They make this test seem difficult. I can hammer out 3x standard proctors per hour (with prep)
Watching it before lab exams
Nice background music, voice and the instruments were also cleaned
Wow i cleared all of my doubts....
Thank you so much .smoothly understanding video fo standard proctor test
The portrait is of Redfield Proctor.. but the man who devised this test was Ralph Proctor. And the portrait wasn't his.

I have learned a lot thanks 👍👍
Good video!!!
The video content is so excellent, congratulations
thank you very informative. it could be better if volume of the music was low to make your voice clear
Could you turn the music up??
clearly explained. ty
Great educational video.
Nice voice 😍
Thanks! Helped a lot!
amazing video very helpful
Our class teacher is presenting this video
superb and simple..
nice technician
really good, thank you for that video
thank you so much

Do you have the ASTM that's directs how to collect the soul sample?
What is the steps to get moist unit weight on this chart? how did you get 15.97?
Why you add backround music
filipino? if so what school, just curious. thanks a lot for the video
De La Salle University
yall know they make machines for this right?
My dad had like 4 of them where he used to work, all of them broke. And it's not like it's going to save you time, it will probably take longer
Music was disturbing to learn
No
best
Je cherche une formation de qualification dans le domaine svp
At 6:25 What are the values you took in the formula for moist unit weight?
Not clear explanation
Hiii
Which standard?
so fast....
theres no need for music in experiments.
Concentrate on experiment
good
Thank for explaination
good
This test is carried on murum ??
KAULE ROHIT no
😂😂😂😂
good
