Determination of Dry Density of Soil by Sand Replacement Method

[@ShivaKumarN-]

I heard few musical tunes while you were explaining in this video.... that's nice🙏

[@ankushpawar34]

respected sir,thank you very much.... this video has helped me alot in easily understanding the soil test.... good work please keep it up.

[@twarakavisaisurendra3069]

Sir I want it in practical writing paper

[@sphoortibaligar6914]

Sir teaching was superb sir... Tq u so much sir... Calculation part really helps lot...

[@KrishnaKumar-xl6vc]

Yes

[@gwcozx2339]

I just got a job because of this video Thanks you sir❤

[@hemantmaurya8831]

Dear sir ,thank you very much this vedio is very helpful to understand FDD

[@premsingh-vo3fu]

thank u very much sir.....i was not attend this experiment in lab.....but exam tym i got ur vidio n did it very well....#grt👍👍👍

[@Mohammad-zv6rl]

Help full videos actually This is a Engineering technical service which you guys are doing such excellent job for other which are not access to the Lab. again thx for sharing

[@vskani]

I think there is a correction in the second part to calculate the weight of sand occupying the hole W1= Weight of Sand pouring Cylinder with sand upto top. W4= Weight of Sand pouring Cylinder after filling the field hole. Now (W1 - W4 ) gives the weight of sand filled in hole along with the weight of conical sand portion at top. Hence to find out the weight of sand occupied on hole only , deduct the conical sand portion W3 Therefore weight of sand on hole is W1 - W4 - W3 ( But, eventhough he has substituted correct values , it is wrongly given here as W1-W4-W2) Anyway I appreciate the author for his work....super

[@mantuapro]

Plz check the instruction in IS Code 2720 part 28

[@vizhithirunanba]

u r correct sir

[@vizhithirunanba]

u r correct sir

[@SangameshKs]

Really satisfied after seeing this comment I too had the same doubt🙏❤️

[@eshithagunasekaran8599]

thanks

[@NoorKhan-pi8kb]

Best channel for test explanation

[@vijaycivil3754]

Very informative and very useful for students and academicians. The way they are conducting experiment is really good and formative

[@shilpakruti]

Your vedios are very helpful to understand the tests.all vedios are nicely explained👍👍

[@rajkumarkallakuri3112]

nice vedio

[@ashhh6918]

Vedio🤓

[@0ngthai]

there are 2 typos in this great video. As Aksay Kumar mentioned, Wsand=w1-w4-w3 (not w1-w4-w2); Also at around 11:30, equation 6, divided by volume Vh (not divided by Wb)

[@devotionalsong2628]

11:30 is not wrong because they multiple it with density of sand

[@sreekumar1748]

Yes correct

[@saikiranvadamudula]

Good explanation👌👌👌

[@saurabhyadav-dx9iy]

Excellent work

Thanks 4 the video.This is so helpful for us

[@afsalputhankudy21]

Hai sir your all video very very helpful to me thank u sir thank u so much sir

[@sajjadshaikh5613]

it's is very useful at the field. thank you!

[@Parminderharman]

sir when u placed sand pouring cylinder on excavated hole i think u hv to remove pit ist becoz the pit will increase the hole lenth by 1 to 2 cm by which sand poured is more that can affect the results

[@bhavanas6768]

tq sir 👍best vedio for understanding this experiment

[@hemanth7844]

thank you sir jii...really this experiment had helped me a lot for my studies

[@laxmankumarsoren8635]

Sir, It is nice Sir, please check, perhaps the Weight of sand in hole =(W1 _ W4 _ W3 ) =1444gm. Thanks.

[@sruthyks4803]

Wow thanks to you sir it was nice🥰

[@yusufrafigaded9776]

Really nice explanation 👌👌👌👌👌👌👌👌

[@kanchanmaurya6594]

Thank you so much sir for uploading this video

[@chandrasankar474]

Thank you sir.super explanation

[@Writtenelement]

nice explanation ..good job jasveer singh..

[@ravishankarsingh42]

respected sir ,in the 2 nd part of experiment ,i.e in the calculation of bulk density of soil , in place of W 2 ( i.e weight of sand in sand pouring cylinder after pouring ) , W 3 ( i.e weight of sand in cone of sand pouring cylinder ) should be used.

[@ayfaayfa9696]

Really good...👍👍👍👍

[@rachnabahuguna6177]

Very well explained sir

[@isaacerutu1705]

good work keep up

[@alvarotello1572]

[@vishaltiwari262]

Sir very helpfull viedo... Thanks a lot But I am not able to understand one thing that from where you are taking the value of water content.

[@nagarajshetti6001]

Such usefull videos

[@bmativenture]

wooow so helpful i really enjoyed the prac so given only a specific gravity of the soil particles, for instance 2.68, how would you proceed to calculate the degree of saturation of the soil

[@dypsking3414]

Very helpful 👍👍

[@mdhasankhan3785]

Very helpful this vedio

[@faisalalenzi3722]

thanks it's very helpful but please explain last part

[@tempestvideos9834]

Thank you Mr. Roboto

[@hopesonlogoh7661]

Very educative.

[@niroshandavid]

i couldn't understand why the technician was hitting the side of the cone? its wrong. when you calibrating the sand you should avoid the disturbance to the cone. its need to be fill in as loose density. if you hitting the cone, that means you giving some static compression to the sand and it will be increasing the BULK DENSITY of the sand.

[@ambujdevi8601]

Very slow explanation but very much knowledge we get 😋☜☆☞

[@nellivamshi9988]

Spb🙌

[@brootv5510]

for Wb = W1 - W4 -W2 is this sure? or Wb = W1 - W4 - W3 ?

[@Broken_Xavier]

Nyc sir

[@pravaskumarmallick3249]

Wel explained sir... Thanks

[@MANIKANDANS-hl2vs]

Very useful to us.. thanks a lot sir.. keep uploading more..

[@UETLHRCED15]

11:14 correction weight of sand in excavated hole= W1-W4-W3

[@vuyyurucharanprudhvisai9985]

Very well explained 🤗🤗🤗

[@nagamani104]

It's very nice but upload all the experiments for civil labs

[@arjunchauhan4046]

Great sir..thankx

[@chinmayghegde5639]

superb....helpful...

[@pravindabhi1049]

Why we use sand which is passing from 1mm and retained on 600 micron

[@gkurumurthygkurumurthy8896]

Thank you sir your good job

[@PriyankaYadav-mw2qt]

Sir ap live class v karwate h

[@AnshumanTiwariMNIT]

thanx a lot sir ,this is really a great contribution .

[@karthikk8340]

very use full sir

[@vinaymohanbhatt4044]

There should be correction at 1:27 min ...in text books and in other platforms it is mentioned that sand should be passes from 600 microns and retained at 300 micron ...…

[@behappyalways13]

Check is 2720 p-28

[@gadibhaskararao8797]

Tnq sir it was so helpful ,, but there is a mistake in calculating the weight of Wb (i.e. weight of sand in hole) By taking W3 instead of W2

[@diprajbhar2733]

Very helpful for partical soil

[@sanjaythakur8487]

nice sir................ thank you

[@PriyankaYadav-mw2qt]

Agar sir ap live class karwate h to hmko v karna hai live class

[@theivamtheivam4752]

Can we use m sand for tis test?

[@Jasmeetstudies]

Good 👍

[@ducvanvt]

at @11:03 should it be W3 or W2 sir

[@muralimonster3652]

Heartful thank to u sir

[@srinivasulusrinivasulu4217]

Why is the depth of hole limited to 15cm in the field?

[@sadanandyadav8960]

Very good 1000000 time thank u

[@rashmithagowda902]

Tq sm sir for tis viedio 👌😚

[@faisalalenzi3722]

last part of the video not clear .. why you take few quantity of soil and add it to what in small container ? and what is the reading

[@angshumanbhattacharjya7028]

Sir please... 1bar volumetric test keise kiya jata hai dikha dijie

[@SHARAT388]

Plz explain ur last methood....dry density=bulk density/1+w gcm3 is 1.74....how plz explain

[@knowledge_science4597]

it is already written in IS 2720-28 (1974), refer it.

[@shalinim9577]

thankyuuu so much helpful video

[@nohelijeanpierre9530]

So helpfully

[@yasshhh9713]

Why so serious sir 😂 The video was informative thank you

[@akshay2078]

weight of sand in hole should be (w1-w4-w3)

[@markforghenkatamba1234]

what is w3

[@mohammedfaizan9587]

You r exactly right

[@vskani]

W1= Weight of Sand pouring Cylinder with sand upto top. W4= Weight of Sand pouring Cylinder after filling the field hole. Now (W1 - W4 ) gives the weight of sand filled in hole along with the weight of conical sand portion at top. Hence to find out the weight of sand occupied on hole only , deduct the conical sand portion W3 Therefore weight of sand on hole is W1 - W4 - W3

[@shashankpathak4832]

Same thought

[@RaviShankar-zo4sg]

standrad sand weight of cone

[@mahantdiaries3276]

Density of soil Kitna Liya sir apny and water content kaise nikala apny

[@syamil.ibrahim]

Thanks for the video

[@niroshandavid]

which stranded method is this?

[@sivahanuman3341]

Sir thank you very much this video help me a lot I can understand this test easily because of you sir

[@dattakshirsagar8008]

Before pouring the sand in the hole ,the tray below the cylinder should be removed.

[@Rewati_Raman]

what is weight in cone?

[@rajdeepnath7939]

Height of Sand Calibrating Container is 15cm, I think?

[@sumaiyayakeen8941]

But this calculation part .need correction Its wb=(w1-w4-w3). Then only we get 1444.

[@diwakarramagowda4557]

Thank you sir and thank you paji

[@abhinavkataria8153]

sir this test is soil compaction or noy

[@markforghenkatamba1234]

You said weight of sand in hole( Wd= w1 - W4 - W2) but you didn't show W2. where is W2 and it indicate what...?

[@santhoshdezno3800]

Simple. W2 is wt of sand in cone portion

[@sanketkhakhiwala5837]

good video

[@EngrFesan]

Sir how to determine if its pass the test?

[@shreyasdamase]

why not he put M as a place W its will make more sense that m for mass and density = mass/ volume mass unit is gram.

[@sribommisetty8882]

nice vedio

[@wazidkhan4560]

sir fdd me calculete me 100+ kyu karte h report me

[@whitemischief3648]

Why do we need to pour the sand in the pouring cylinder upto 10mm from the top?

[@narayanakanta1630]

if we not exceed 10mm..we don't observe the movement of sand in cylinder
