TEST FOR WORKABILITY OF CONCRETE - SLUMP CONE
ฝัง
- เผยแพร่เมื่อ 4 ก.ย. 2014
- The ease with which one can use concrete is called workability. It is one of the physical parameters of concrete which affects the finesse, strength and durability. Here’s how you can check the workability of your concrete.
- วิทยาศาสตร์และเทคโนโลยี
For everyones benefit, acceptable safe slump for reinforced foundation walls/footings/pavement 25-80mm, beams/columns 25-80mm, slab 50-100mm, piling 100-150mm. Beyond these values are not safe.
Thanks man
As per IS 1199 slump cone is filled in four layer,so don't confuse with comments. This video is wonderful and precise

Wrong
Not ASTM C 143 but Indian Standard (IS-1199) ?
Hey fantastic work guys. Thank you for explaining it well - very helpful!
"First you need to steal a traffic cone"
lol
You can order on Amazon
Amazing, clean explanation .
Very simple nice explanation, Thanks a lot.
Well explain and simplified. Thanks ultra pls keep educating the world with all ur heart. I enjoyed your video.
I like your teaching method and the way you share the knowledge. 👍👍 Keep up the productive work.

it is a good work guys pls do the exact procedure for consistency, initial and final setting time of cement
What a useful and clear explanation thank you 🌹
Thanks for explaining the information in such a way that everyone can understand. Good lesson.

rotate of the cone to create collapsible and shear slump should be lifting gratually
Slump test express the consistency of concrete mix, workability is measured by " Compacting factor" or " Remoulding test by Jolting" or " V.B test".
I actually picked out a real practical in slump test. But I never got the accepted height or ranges of heights that are good
AWESOME, now I can go take my GC exam!!! :)
We need more videos related to this and also construction sites
Thank you DCRM!
Thanks for this explanation now I can defend my project well

Great work
I watched a 5 hour pour of a hotel foundation in Spain and not one slump test was undertaken.
Goodluck on that building! 😅
Thank you sir
Nice practical i appreciate you sir
Very helpful of concrete workability test
Thank you
very good lecture.
Why was no information given on how much slump is ideal?
Good test
simply superb........
Nice information
ATSM C143: "Immediately remove the mold by raising the mold in a steady, vertical direction. *** There should
be no lateral or torsional motion of the mold while lifting. ***"
Yep, i don't know what code does this channel is following.
th-cam.com/video/eymDP1_oHbo/w-d-xo.html
good test
very good voice and pronunciation
Why is it undesirable for a shear or collapsable slump test? Its great to know what is preferred but equally important to understand why
I get that but what are the dangers when contractors the slump test fails and contractors use it anyways. I say this because many contractors provide shotty work. In what ways does it effect the integrity of the concrete? Are their any telling signs?
Aside from affecting ease of work (pouring using pumpcrete tend to be difficult if slump is too low), it may result to severe honeycombing on structural members, reducing integrity of the structure.
*Point To be Noted:-* Slump length measured from UP Side 🙂
Interesting video

I had done in lab of BCE Bhagalpur
no rotation allowed when lifting the cone see ASTM C143
Carefully in a vertical direction. By a steady upward lift with no lateral or torsional motion.
Some more information...is desired!!
Best quality
thank you so much sir very help full
walal seetahey good job hadan halkan wax ka baraneysid ila soo xiriir hada u baahatid in si fcn usii fahantid.Hadii ad ACI test sameyneysid ninkan qaabkisa ha raacin waayo waa khalad waadna ku dhaceysa taas ogow.
Nice
slump cone also out of calibration and slump should not be rotate while lifting
10
and for the blows not go proper (final layer)
what is the range of slump height for a concrete to have a good workability?
50 TO 75 MM
Very help full
fantastic work
THANKS,ULTRATECH ......
Thanks
Superb
Great information here. Thank you so much sir
Why frustrum of cone shape is preferred for slump test please explain
to maintain the potential energy of the concrete along the height
Exaplained very simply. thankyou
You're welcome. Hope you found the above information useful. 😊
@@UltraTechCementLimitedyes, it is very useful for me.

The slump mold is filled in three layers (ACI grade 1). Not in four layers like you said. Sorry wrong.
Dear.....they're perfect.check your basics once again.
Good stuff engineer. Well explained

I am getting zero slump . what should I do? please help
Thank you.
How do you analyze the results after measuring the slump
pick up true slump results as ideal choice.
thank u sir ....
Watching this video just minutes before exam
Sir, what are the slump values for different work like road , slab , columns etc.???
5 inch
In Australia for normal concrete we mix 20mpa 20mm aggregate 80 mm slump when it is being tested . A wetting agent can be added after the test to make the concrete easier to work .
Thank you bra now I have practical view of slump test
Great
Thank u sir
How to take the water content???
Slump cone is rotating while lifting the slump cone. it is lifted in vertically and check the measurement.
Please vee-bee cosistometer test ke baare me bataye
nice
Tnx brooo
what is green concrete bro explain
Nice explanation
Hello Tanjim, we are glad you think this, for more information about us, please do visit www.ultratechcement.com . Regards, Team UltraTech.
cool
ok.. what causes shear and collapsible slump and is it best for lantern or beams..because concrete needs for such work should be collapsible so that it may fill up all air bubbles in concrete

Hello,
We would like to inform you that shear or collapse slumps in concrete are due to the majorly wrong proportioning of aggregates, higher water-cement ratio, and maybe the wrong dosage of admixture. Hope this solves your query.

hi. just wondering. If the cone if filled, should the cone be lifted right away it is filled or should i wait for 1 or 2 minutes? thanks
once you filled the cone you should lift it right away
thank you!
gud
Which code dictates that the slump cone is filled in 4 layers?
IS 516, IS 1199
Sir please tell that how optimum moisture content is achieved on the site
I want this
I started hallow bricks unit so i want this mixture
Hello Pampapathi, could you please elaborate your query?
Regards,
Team UltraTech.
What is the IS code used
Now 3 layers... New code.. some one told please reply any one three layers or four layers
Process bhi to bataeye kayse kiya jata hai
What test method is this? you are not following ASTM C143 or AASHTO T119

砂利が多いし、5cmでこの水加減…
後、スランプコーンひねったら正確な数値にはならないかと。突き方にもムラがあったし、３層目なんか突き棒が先しか刺さってない。
あれじゃ崩れますよ…
I don't know China
tamp free fall?
Three layers only as the size of the cone is too small
