Explained very nicely. Slump test is done to test water cement ratio which has direct impact on the design strength of concrete. The reduction in height after the cone is removed depends on the type of concrete vis a vis design strength. For example concrete of M20, M25, M30 etc have different reductions in height after the cone is removed.
For slump test, number of layers is 3 and for each layer the tamping should be 25 times. Care should be taken that while tamping 2nd layer it must not penetrate 1st layer and same for 3rd layer, this test should be completed within 2 min, Ref: IS 1199(part-2):2018 (but your video is informative, keeping growing good luck)
Test taken to make a video l don't think in india any bulider will waste time in such tests concrete comes pour it work done go home that is regular practise time pass video
Now the standard has been change. You must penetrate the previous layer by 1 inch. The way he test the slump is bulshit. Slump must be fill in 3 layer. 1st layer 7 cm. 2nd layer 16 cm. 3rd layer 30 cm. Tamping in each layer must be 25 time.
As per IS code 1199 2018.......We fill the slump cone in 3 layer of 25 time stroke each...The hole procedure should be done within the 3 min time frame
At 21:32 jo 22.5 hai wo metre me hona chahiye kyuki 150mm*150mm=22500mm ata hai aur isko metre me convert karne pe ye 22.5metre ho jata hai.....aur 600kilo N hai ya only Newtown? Bhai mujhe kuch jagah calculation explaining me error laga hai...

Thankyu so much sir ji👏👌👌Mene to apke ye test ke video pahle dekhe the aek aek krke lekin aaj fir se revision ho gaya sirjii superb plz sir or video banao jisse hame pura knowledge mil ske 🥰🥰👌👌👌🌷🌷🌷
Pillars are already constructed upto base level.but sudden shortage of money had kept the construction work on suspension for five months. Do u think it will damage the bar that are open from the pillars
Cement wash the exposed rebars including stirrups to prevent formation of rust. Rust is very dangerous as there won't be proper bondage with the concrete if the rebars have become rusty.
The slump test is considered failed as per bs when the concrete collapse. The concrete is too watery. Desired values are between 40 and 80 unless it's a pump mix with extra cement. The method for raising the cone is inappropriate, he should lift the cone from a higher or standing position. Anyway good initiative to show test on site. Kudos
Sabse pehele app wo concrete nikal kai apply anti rusting liquid after that apply some binding liquid and fill with micro concrete lastly plaster the surface for finishing App pehele chk karlo kaha sai seepages hai ki nahi usko band kijiye
Please, please Slab ke vibration ke bareme datail me video banaye, slab ke size ke according standard vibration kitna hona chahiye oh commen people vibromeeter application se kaise count kare yeh bataye, mera 10x12 ka living room hai usme vibrometer se ek standard football ko 6ft hight se chhodne se 2.5 mm tak ka vibration show karta hai (6ft se chhodne se, na ke patakne se ) toh kya yeh sahi hai?flat new hai
Imp question whether u can answer it or not Till which grade Slump test is carried out??M30/40/50 Simultaneously u forgot about one test of concrete which the people are unaware of. Waiting for your reply...
Sir ......area of cube is (side )×side ×side ....and you are taking only (side × side ) and compressive strength check for 28 day ....the calculation is (30×99/100) If l m not wrong ....plz correct me ??

Right
I also noticed same he said 4 layer 25-28 tamping Totally wrong.
And again said 35 tamping in cube filling, he doesn't know any thing
@@atoullshukkla5625 25 time is right
I can proof
Apka jo KN/Nmm2 ka volume ata hai usko grade of concrete se divided karo usse pata chalega ki kitna % hai
........
adhoora gyan nhi please, KN/mm² ka volume? ye kya cheez hoti hai yrrr
value likho typing error mtt kro boht freshers isi me confuse ho jayenge

Thank you brothet for giving practical information👍🏻🤝🏻🙂
did you made a mistake in the estimate of 28days strength? you wrote 30 * 28 / 100 , whereas it should be 30 * 99 / 100, am i right ?
Correct bole, Yhi me bolne vala tha
22.5 kaise liya sir ne?
th-cam.com/video/sJ7bp_fAW74/w-d-xo.html
please clear this doubt civil site visit. i have this doubt too.
Strength = load/ area of mould
= load/22.5
MASS Scientific Sales Mr. Mahipat is very good work
Cement ke grade par bhi nirbhar karta hai na sir
best valuable civil engg site technical knowledge
Jaldi se jaldi 1 million hoga
1 sample pe 3 specimen ready kiya jaata h na..???
how did you get area of cube as 22.5 ? if you divide 600 with 22.5 how comes your strength of concrete in kn/mm2. please rectify your mistakes bro.
150x150
150x150
(15*15)/10
150x150 = 225 ..... Y 22.5 ????
22:25 Actually 7 days me 67% strength and 14 days days मे 87% strength achieved होनी चाहिए according with IS code 🙏
Which IS code
Apne konse IS code me dekha

Chemical coat for rods will be added advantage
