TEST FOR WORKABILITY OF CONCRETE - SLUMP CONE
Вставка
- Опубліковано 4 вер 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.
- Наука та технологія
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
Hey fantastic work guys. Thank you for explaining it well - very helpful!
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) ?
Amazing, clean explanation .
Very simple nice explanation, Thanks a lot.
What a useful and clear explanation thank you 🌹
Well explain and simplified. Thanks ultra pls keep educating the world with all ur heart. I enjoyed your video.
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 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
well explanation sir thank you......
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!!! :)
"First you need to steal a traffic cone"
lol
You can order on Amazon
Thank you sir..
Clear explanation...
Very helpful...thanq
Thank you DCRM!
We need more videos related to this and also construction sites
Useful information.. appreciated

I am getting zero slump . what should I do? please help
MAJOR CIVIL ENGINEERING TESTS
Why was no information given on how much slump is ideal?
How to take the water content???
very good lecture.
Why frustrum of cone shape is preferred for slump test please explain
to maintain the potential energy of the concrete along the height
very good voice and pronunciation
Thank you ultra tech. This helps me for my lab exam preparation

what is the range of slump height for a concrete to have a good workability?
50 TO 75 MM
Interesting video

Thank you
How to do it according to astm c143 standard
simply superb........
Nice information
what is green concrete bro explain
tamp free fall?
Some more information...is desired!!
Great information here. Thank you so much sir
What is the IS code used
Nice
good test
Process bhi to bataeye kayse kiya jata hai
Good test
Thank you bra now I have practical view of slump test
Very help full
How do you analyze the results after measuring the slump
pick up true slump results as ideal choice.
Thanks
thank you so much sir very help full

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.
Please vee-bee cosistometer test ke baare me bataye
Sir please tell that how optimum moisture content is achieved on the site

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
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 .
I had done in lab of BCE Bhagalpur
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.
ua-cam.com/video/eymDP1_oHbo/v-deo.html
slump cone also out of calibration and slump should not be rotate while lifting
10
and for the blows not go proper (final layer)
fantastic work
Superb
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
Hi Abid,
Thank you for your query. Our experts will answer your question shortly.
Meanwhile, you can watch homebuilding-related videos here - ua-cam.com/users/UltraTechCementLimited

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.

Good stuff engineer. Well explained

What is the procedure for Slump test with Egg shell powder as 10% replacement of cement??
Dear Sakshat, please message us your location in detail, our team will get back to you.
@@UltraTechCementLimitedWhatsapp Number please
I watched a 5 hour pour of a hotel foundation in Spain and not one slump test was undertaken.
Goodluck on that building! 😅
*Point To be Noted:-* Slump length measured from UP Side 🙂
Exaplained very simply. thankyou
You're welcome. Hope you found the above information useful. 😊
@@UltraTechCementLimitedyes, it is very useful for me.

Watching this video just minutes before exam
Tnx brooo
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.
THANKS,ULTRATECH ......
RIST walei 🙌🏻
Thank u sir
Which code dictates that the slump cone is filled in 4 layers?
IS 516, IS 1199
I want this
Great
Slump cone is rotating while lifting the slump cone. it is lifted in vertically and check the measurement.
What test method is this? you are not following ASTM C143 or AASHTO T119

Thank you.
Nice explanation
Hello Tanjim, we are glad you think this, for more information about us, please do visit www.ultratechcement.com . Regards, Team UltraTech.
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.
I started hallow bricks unit so i want this mixture
Hello Pampapathi, could you please elaborate your query?

Spr bro
please so slab ,cloumns,fotting
What slump ...??
temperature of concerte. Maximum and minimum. Give me answer.
Maxium 28 minimum 32
Structure concrete maximum 32°
why the slump cone is conical ?
Hi Siva,
Slump is a test to understand the Workability of Concrete. A cylinder may not just slump, it might also fall apart due to a lack of cohesion. The angle ( called the angle of repose) is the steepest at which the sand grains don't slide down the hill. This limiting point is the same all the way down the pile and that's the angle of the cone & that's the reason slump cones are conical.

Now 3 layers... New code.. some one told please reply any one three layers or four layers
Them adlibs though
