What is Concrete Slump?

[@Masterchif434]

i had 20 questions and this video answered all of them without having to go wild on an astm! thank you!

Dude, my wife was right I should’ve watched these videos before I started training this week because Tuesday he’s rattling off all this shit and I had no idea what he was talking about but now when I go back today I got a better understanding. Thank you.

[@rossmayer2380]

Um if he says 'Um' one more time I swear 🤣

[@junglistmanner404]

I hate that I read this comment before I finished (the video) 🤣, but's he's very articulate and given that he's knows this much about concrete, there's a lot of f**ks and s**ts that normally roll of the tongue, that are definitely not being said. However, I still hate that I can't rewatch this and not hear "um" everytime he says it. Still a great video and as a new ready mix driver, this is 100% on my radar to help me slump up and not get railed by the pump operator or swamper or 19yr kid with an ego on site Edit: (the video)

[@leogolive]

Sounds like normal talking to me. He makes sense, he’s knowledgeable and enunciates clearly.

[@jb314stl]

Great video.. chill on the um

[@DecoCreteTV]

Thanks for the comment!! Jeff was around 15 ums per minute in this one🤣🤣

[@borsistephen]

Did anybody count the umms?

[@nickforeman757]

Hard to get an explanation like that from your superiors.

[@hehehe9618]

So adding more water to your concrete would increase the fluidity of the concrete, but then it would also lower the strength of the concrete?

[@DecoCreteTV]

Correct! 👍

[@wsalt1221]

Great information sir. Appreciate you sharing your knowledge. Do you have any videos explaining water-cement ratio???

[@DecoCreteTV]

Thanks for the comment!!! We don't have any videos on that right now. We do plan on making one in the future though, stay tuned👍

[@williama.zinnikas7504]

Great explanation! Short, sweet, and to the point!! Thanks for making this helpful video!!!

[@williamd.costigan3]

thanks for the video. I've been pouring small areas of concrete for years and I knew that a 6 vowed better than a 4. I also knew that add mixtures were stronger than adding water, But that official measuring cone was really cool. I'm totally serious when

[@DecoCreteTV]

Glad we were able to help!

[@ickycrane684]

Great video. You explained what I was looking for in a perfect way. If I had a drink for every time you said “uhh” or “ummm” I would be dead drunk though. 😂 No offence though. Super great video. Thank you!

[@rayertman]

Great video. So if I were to be screeding a 8 foot driveway by myself, would that be a good reason to increase my slump? Also, with a higher slump, would that generally increase the time between floating and finishing?

[@DecoCreteTV]

6in slump would be a good average for pouring a driveway. pouring a little tighter than that will increase strength but will be harder to work. pouring wetter than a 6in slump might make things easier but you will lose strength

[@fun782house]

Interesting thank you viscosity comes to mind

[@DecoCreteTV]

That would be a good way of looking at it. Thanks for the comment!

[@soorajullas8231]

Could you please tell more about the measurement we need to take? What cm is perfect?

[@DecoCreteTV]

The perfect slump is going to depend on the application, that's where the measurement comes in! measure from bottom of the bar to the center of the slumped concrete

[@transmitterguy478]

Cool, I never knew!

[@cluelesssam6975]

Thank you

[@fish97826]

Technically according to ACI you're supposed to used the flipped cone to measure with the rounded rod on top although I suppose you can use the handle, it'll technically get you failed during examination, now in the field is different of course, no problem then

[@DecoCreteTV]

Thanks for the comment!

[@dustinrobertkimball]

I wish I could count how many "um"s were in the video. Not sure I I can count that high? 🤔 but seriously man you obviously know your, um, shit and um, can actually speak really well. You articulate and get your point across amazingly well. 👏 Thank you!

[@Minecraftisbeast47]

I swear you said "Uh" or "Um" like a thousand times hahah

[@CeeMoe1]

I just started working with Ozinga as a ready mix driver and i am having such a difficult timing fully understanding the conversions of slump on the PSI meter and calculating water to the mix. it has to "click" soon but i think if i had a chart or something maybe I'll understand.

[@DecoCreteTV]

Thanks for the comment!!! Hopefully, the new job is going well for you👍 We don't have much experience with the conversions on a psi meter, our background is more in pouring & finishing the concrete rather than the ready mix side. You might be able to find a chart online somewhere, or maybe someone at your company would have something for you. If not, my advice would be to talk to some of the drivers who've been driving for a while to see how they do the conversions. You could even make your own chart to follow based on their info. It could just be a handwritten thing to keep in your truck, or you could make it look nice and share it with the other new drivers. As for calculating how much water to add, a good rule of thumb is: 1 gallon of water per yard of concrete will bring the slump up 1 inch. So, say you have 6yds on your truck and it's at a 4-inch slump. The contractor says he's looking for a 6-inch slump, you would need to add 12 gallons of water. Hope this helps you out. Thanks for watching!!!

[@toxeyfrench]

I um wanted um to learn um about slump um thanks for um the video.

[@DecoCreteTV]

Um thanks for uh watching!

[@yoursola]

Thanks for this info! If I want to use an 80lb bag of Quikrete concrete mix, how much water would I need for a 2-3in slump?

[@DecoCreteTV]

Follow the instructions on the bag and mix accordingly!

[@rossmayer2380]

Dude um that my um thought exactly.. um

[@TheBroknPezDispenser]

uh, you too!? uhmmmm.

[@kajekage9410]

a gallon... per YARD of concrete will change the slump that much?

[@DecoCreteTV]

yes it will👍

[@highonlifefishing4007]

So if i have 7 yards I’d need roughly about 7 gallons to bring up the sump one inch?

[@DecoCreteTV]

yes that is correct!

[@wademartin8822]

Great video!

[@mikejustice1196]

You put the mud through a 1 1/2 sieve then filled the cone to 1/3 then you tamped the mud 25 times with the rod then you filled it to the 2/3 level and tamped it another 25 times then filled it again to the top and did another 25 right? Just wanted to make sure there’s no misinformation about this testing.

[@DecoCreteTV]

Thanks for the comment! I've never heard of or seen anyone put the mud through a sieve before a slump cone test. Other then that, yes, fill the cone 1/3 at a time and tamp 25 times with the rod after filling each section. Here's a link to an ACI slump test video and one to a PDF explaining the procedure. Thanks for watching Deco-Crete TV!!! kzbin.info/www/bejne/oHW4goJjl9Nrprc gatesconcreteforms.com/wp-content/uploads/2014/10/slumpTest1.pdf

[@Victor-fb2ik]

The um but other than that. Awesome video.

[@lumal12]

is it safe to say that adding 10 gallons to 10 cy, the slump would increase by 1 inch ?

[@DecoCreteTV]

Yes that is correct!

[@PNWNature]

Very helpful!! Didn't know there was a device for measuring slump; interesting 😊

[@DecoCreteTV]

Thank you!!! Definitely a lot of um's in this one! Like 10 per minute😂😂

[@CarlosGarcia-ls4hn]

Can a good, experienced driver, be able to tell the slump just by sight?

[@DecoCreteTV]

Thanks for the comment! An experienced driver can get the slump close by sight, but the only way to know exact slump is to use the test cone. Most residential jobs don't require an exact slump and no cone is needed. Thanks for watching Deco-Crete TV!!!

I have seen for the first time on youtube a 100 slump.....it was so much water it would probably shrink 3 inches while drying. totally slumped out. like self leveling all these guys with rakes just standing there as the concrete flows like a mudslide.

[@DecoCreteTV]

😂😂

[@eliezeranpan8704]

Can you explain the calculation?

[@DecoCreteTV]

One gallon of water into one yard of concrete will bring the slump up one inch

[@jasoningraham1393]

I think our local concrete plant needs to watch this we never get what we order always order 4 comes as a 6

Can you tell the slump right away?

so its like viscosity?

kinda yes

[@anthony6298]

Hello. Getting ready to pour 5 yards over poly (garage floor). My order recipe will be L10/ 6.5 sacks. Because of the poly, I would like to use a water reducer to minimize bleed water as well as improve workability. Would like a 4" slump with a 6" or 7" workability. How would that be ordered? Or will the supplier know just what to do? Thank you for your videos!

[@DecoCreteTV]

That is a good way to go about it. Explain the situation to the ready-mix plant and request mid-range water reducer. Thanks for watching Anthony!

In reality, I never use this test to predict how workable my concrete is, I just use my good workmanship standard. :)

Thanks but this video is not done by an engineer explaining how slumps are related to water/cement ratio, workability, permeability and target strengths of concrete using various methods of placements on site e.g. by skips, pumps, etc... not satisfied with this video
