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
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
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 🥰🥰👌👌👌🌷🌷🌷
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...
Video Accha hai..! But Slump test ka Aapko idea nhi hai material dekhne se hi lag rha hai Slump 110-115 Se jyada nhi hai...! Segregation bhi nhi hai..! Bleeding or Segregation kya hota hai Site Per Acche se kaam kerne se Pta Chalega
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.
Mai technician ka kaam Karta hu 8 sal se slump mai stamping karne ka tarika Or utjane ka tarike sehi nehi hai . concrete dekhke malum hoga gaya 100 slump ka upar nehi jayega

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
Tremendous job you are doing sir .... Keep it sir

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
7 din ke liye apne 65 se multiply karbaya or 28 din ke liye direct 28 se ye kya baat Hui engineer sahab
1 sample pe 3 specimen ready kiya jaata h na..???

Hello Assalamualaikum good to see this video love it ...
ASTM standard as per 3 layer not 4 layer flings slump cone also lifting slump cone within 5-+2 second asper ASTM
Cube should be filled in 3 layers and slump cone should be filled in 4 layers
@@logiclessmind1525 please let me know standard?
Thnkuu for giving knowledge concrete testing
28 days ka calculation wrong hai 30*99/100
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 ????

Chemical coat for rods will be added advantage

Sir 0 to 5 m3 quantity ka mtlb kya hai. Ek bar jo concrete ban rha hai vo ya din bhar me jo bn rha hai vo ya total work me concrete bnega vo
Bhai RMC m 7 m^3 se jyada concrete nhi aata so jitna quantity v RMC m aata h site p usi ko measure Krna hota h or uska report v banana padta h
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
Cement ke grade par bhi nirbhar karta hai na sir

Sir plz ek video brick test ka bhi or tiles ka bhi .waiting for positive response
As per BSEN or ASTM for the slump testbitz only 3 layers...BSEN its says equal hight of layers,ASTM its says equal quantity for layers
Sir sirf cone ka hight 300mm he aap jab check karteho tab app handel se kartho, handels se surface ka hight 300 nehi he jyada he
