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.
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)
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!
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?
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
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
Great video! Very informative, the one critique I would say is too many umm's. Sticks out to me like a sore thumb and makes it hard to focus on the actual info. Other than that great video! Thank you for putting this out there
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
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
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.
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.
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!!!
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!
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!
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
Brother work on your speech skills. Be consciousness of the word "um". It's an undesirable word when speaking or writing. Your content however is excellent.
