As per IS 1199 slump cone is filled in four layer,so don't confuse with comments. This video is wonderful and precise

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.

"First you need to steal a traffic cone"

Thanks for explaining the information in such a way that everyone can understand. Good lesson.

I like your teaching method and the way you share the knowledge. 👍👍 Keep up the productive work.

What a useful and clear explanation thank you 🌹

Slump test express the consistency of concrete mix, workability is measured by " Compacting factor" or " Remoulding test by Jolting" or " V.B test".

Hey fantastic work guys. Thank you for explaining it well - very helpful!

AWESOME, now I can go take my GC exam!!! :)

Well explain and simplified. Thanks ultra pls keep educating the world with all ur heart. I enjoyed your video.

rotate of the cone to create collapsible and shear slump should be lifting gratually

Very simple nice explanation, Thanks a lot.

I watched a 5 hour pour of a hotel foundation in Spain and not one slump test was undertaken.

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. ***"

no rotation allowed when lifting the cone see ASTM C143

*Point To be Noted:-* Slump length measured from UP Side 🙂

Thank you ultra tech. This helps me for my lab exam preparation

it is a good work guys pls do the exact procedure for consistency, initial and final setting time of cement

Thanks for this explanation now I can defend my project well

Amazing, clean explanation .

Watching this video just minutes before exam

We need more videos related to this and also construction sites

Very nice explanation this videos

Useful information.. appreciated

The slump mold is filled in three layers (ACI grade 1). Not in four layers like you said. Sorry wrong.

Thank you sir.. Clear explanation...

Why is it undesirable for a shear or collapsable slump test? Its great to know what is preferred but equally important to understand why

Thank you DCRM!

Nice practical i appreciate you sir

Good stuff engineer. Well explained

Why was no information given on how much slump is ideal?

The ease with which Ultra-tech explains the concept and things is called workability of ultra-Tech...

Slump cone is rotating while lifting the slump cone. it is lifted in vertically and check the measurement.

Very helpful of concrete workability test

Exaplained very simply. thankyou

well explanation sir thank you......

Thank you sir

Very helpful...thanq

very good voice and pronunciation

MAJOR CIVIL ENGINEERING TESTS

Interesting video

slump cone also out of calibration and slump should not be rotate while lifting 10 and for the blows not go proper (final layer)

very good lecture.

Very nice advice

Subscribe,like,comment kar diye

Why frustrum of cone shape is preferred for slump test please explain

Sir please tell that how optimum moisture content is achieved on the site

How do you analyze the results after measuring the slump

I actually picked out a real practical in slump test. But I never got the accepted height or ranges of heights that are good

Great information here. Thank you so much sir

what is the range of slump height for a concrete to have a good workability?

RIST walei 🙌🏻

Nice

Very help full

Thank you bra now I have practical view of slump test

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

The slump cone shall be removed by raising it vertically, slowly and carefully, in two to five seconds, in such a manner as to impart minimum lateral or torsional movement to the concrete. (extracted from Construction Standard of HKSAR) You guys did twist the cone

Great work

Nice explanation

Nice information

Sir, what are the slump values for different work like road , slab , columns etc.???

What is the procedure for Slump test with Egg shell powder as 10% replacement​ of cement??

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…

thank you so much sir very help full

Which code dictates that the slump cone is filled in 4 layers?

Is it 1/4 of the ht or the volume? Thanks for the reply

simply superb........

Good test

tamp free fall?

Thank you

I am getting zero slump . what should I do? please help

the tamp should be freely drop..not force it by hand..

I had done in lab of BCE Bhagalpur

Some more information...is desired!!

What test method is this? you are not following ASTM C143 or AASHTO T119

You’d fail hands on portion of ACI test if you followed this procedure.

every layer should be tamped 25 times, not stroked 25 times. Tamping method is wrong. This is the common mistake in most of the sites. At least ultratech should do properly.

What is the IS code used

good test

u are sly😂😂...... no twist when lift the cone....😂😂😂

Thanks

How to take the water content???

fantastic work

Not four layers, three layers and the cone should not be rotated

Please vee-bee cosistometer test ke baare me bataye

slump should not be rotate while lifting

How to do it according to astm c143 standard

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

Wow that was bad, you fail ACI Testing

Process bhi to bataeye kayse kiya jata hai

Superb

what is green concrete bro explain

nice

THANKS,ULTRATECH ......

Best quality

*I also have youtube channel related to CIVIL ENGINEERING PRACTICAL KNOWLEDGE.*

Great

You need to dampen the cone and the base plate before putting any concrete in. You don’t clean the concrete off the top with a trowel. You use the tamping rod in a screeting motion. You don’t twist the cone as you pull up. It must be straight. Also you don’t measure to the highest point of the concrete. You measure to the displaced center of the concrete. Read the ASTM standard please.

thank u sir ....
