Thank you for making this video Prof sir. Really it's useful for both students and as well as site engineers. And 1 obligation kindly mention in this video IS code book also for this test.
But this process is not as per IS Code 2386 part 2..as per IS Code formula is 100/w1(1000*ws/V-0.8) and equipment name is sadimentation peepet for sand silt and clay content
Very nice video Sir. But how to determine separately the % amount of clay and silt in the mixture? How to determine whether it is clayey sand or silty sand? In the whole video, there's no mention about clay.
