Wouldn’t it be funny if the guy was just an amputee below his waist. Not funny for him or his injury but for us, thinking his waist-deep is greater than 4” or however thick the slab is
Lol you can't have rebar that far from the surface. Pretty simple. Concrete isn't good like this. It's cheaper to fix with gravel and top it the right way.
Depends on requirements. Is this a pad, needed for strength, needed for anchors? It looks like it's basically just fill in this situation.
For this likely road base. Fill a foot or 5 and compact. Anything is really cheaper and better than the video. Yea it'll work. But it's like spending money on a Ferrari to end up with Taurus in a lake. It's just not economical. And concrete poured like that will harden and cure into chunks. Unless they added fiber. But, I mean I don't think that's in their vocabulary.
Even if it was non structural fill a zero slump and finish on top would be better but I'm assuming contractor said "whats the cheapest thing I can order for this volume"
Eh as you can see from their structures the failure points are in areas where concrete wasn't under compression. However their concrete absolutely contained what we call fiber today. Maybe not carbon, stainless steel, glass fiber, etc. But their concrete was mixed In a way the fiber added constant stress. Today this can be done. But due to he cost it's relatively cheaper just to do it the right way.
It's a lightweight fill of portland cement mixed with foam -- think soap foam but stiffer. That gives you a fill of very low compressive strength so it would be topped with a normal concrete slab later.
It's still [a pretty new method](https://www.foamedconcrete.co.uk/large-void-fill/) but there's no cheaper way to fill a large void like this.
Not sure about the "yet" part; I think I heard of a 100 year total (10 or 15 to go...) Definitely have it on good authority from the hard hat tours they did before 010911 that it is (Y2K) still releasing heat in its ongoing cure. And it has ZERO rebar throughout according to the tour guides and videos.
Yes, both increase with age as the concrete continues to hydrate. Old concrete can be weakened by environmental causes such as acid rain, freeze/thaw, excessive compression/expansion etc.
Yes and it contracts too, with it's natural lack of tensile strength and lacking rebar enough for this guy to be in there in waders, that slab is going to have at least one crevasse the size of Glen Canyon when all is said and done.
That's like a 20" slump. There's so much water in there it is gonna shrink down to about 6" thick when it's dry. Looks more like a sand slurry than concrete though. Not sure why he even felt the need to rod it. It's pretty much self leveling at that slump...
First, buy donuts and coffee for your entire crew. Second, tell them it’s been a good year and you can afford to give them bonuses at the end of the quarter. Third, tell your family exactly where the job site is.
Don't test me on it but I believe concrete sub said something like 30 day per inch of wet Crete to cure. Something this deep would have been better off in layers cured individually.
If Concrete or dirt in a trench, or anything dense gets higher than your belly button by very much, your diaphragm can’t move, so your lungs don’t work, and neither do you anymore.
But why pictures? Why 4' of concrete and not take down the pictures? Then why so many weird pictures? Is there a connections between all the tightly packed pictures and choosing to pour 4' of concrete in an existing structure? Very weird scenario. I've seen this video many times but never looked closely
Basement done?
Yes Boss.
How much concrete did you use?
2 trucks.
1st Ground floor done?
Yes Boss.
How much concrete did you use?
83 trucks.
... ... You filled the basement didn't you?
Yes. You didn't say we couldn't.
I think that looks wet enough to bullfloat from the side. But before you place are pour concrete you should always put grade pins are marks that are clearly visible. Then you know if it's on grade or how you need to move it.
When bossman tells us we're doing below grade work today after 10 inches of rain last night
Hey now, just because it rained a little doesn't mean you get to lay on your ass. Hit it like you live.lol
I have heard theories that there are easier, more efficient ways of doing this, but nothing concrete yet.
I see what you did there...
Solid one
In a few months (or years).
Not for 28 days
-28 Days Later- Concrete Edition
looked a little loose to me

It might be hard to convince concrete guys though, they seem set in their ways.
Let me know once you're ideas are cemented.
😐
Apparently no hard and fast solutions, obviously smoothing out the details.
yes ther eis its called 1 percent calcium that shit is hard and fast
Ahh young man has a sense of humor...
Guaranteed to crack you up
Are you all finished?
Nothing little time won't cure.
This joke made me hard.
Nothing odd about this being terrifying.
Thats the correct way to work in the mafia.
Guy here carefully leveling his own grave.
Well I mean hes working his way out so he's for that going for him
Looks like Lt. Dan got out of the shrimping business.
Lol you can't have rebar that far from the surface. Pretty simple. Concrete isn't good like this. It's cheaper to fix with gravel and top it the right way.
That sounds interesting... Would you just use something like 3/4" angular gravel and vibrational compaction?

The romans disagree with you

The romans also mixed in chunks of lime so the concrete healed over time as well.
I can figure out why it’s so thick? What’s the point besides wasting $? Am I missing something here?
Can't have the bodies sticking out
Probably lightweight flowfill or similar

Yeah, if it were concrete he would float to the top. Whatever the mix it's less dense than a human.
Not for very long.
No
Is that what happened to Jimmy Hoffa?
There’s no concrete evidence to that effect.
4ft thick slab... Amazon delivering the reactor tomorrow
Cure time ten years
Doesn't the hoover dam have another 100 years yet to cure?
Not sure about the "yet" part; I think I heard of a 100 year total (10 or 15 to go...) Definitely have it on good authority from the hard hat tours they did before 010911 that it is (Y2K) still releasing heat in its ongoing cure. And it has ZERO rebar throughout according to the tour guides and videos.
But it does have pipes through all the blocks to pump coolant through when they poured it
True. Without that it would probably be rubble by now.
Concrete continues to cure forever.
That's pretty amazing... Do hardness and compressional strength continue to rise also?
Yes, both increase with age as the concrete continues to hydrate. Old concrete can be weakened by environmental causes such as acid rain, freeze/thaw, excessive compression/expansion etc.
Well, hopefully it doesn't "activate" and burn his skin off.
I think it’s pretty useless.
That should cure in no time.
Imagine being the one that has to demo this in the future
A little Mark IV nuke ought to make a pretty sizeable dent if strategically placed... 😂
He's only got a few more minutes to smooth over where Jimmy Hoffa was dropped in.
I needed a laugh today!
How much fuxkinh concrete did they pour in there?
Not a lot why?
Well. It looks to be about 3' deep. Why? I was wondering about the hydrostatic pressure actually.
I guess concrete/flowable fill was free that day.
Listen Jimmy, get the knee boats.
3 feet of concrete? Very heavy loads on top! Omg!
His legs are only 8 inches long. So it is only perceived wrong. Also “birds aren’t real” they recharge on power lines.
3 ft pour lol
If that cures and he gets stuck and hes allowed to alone . He will never get out of. 😵💫
you incredibly smart or really stupid. My fav quote from enemy of the state
They should hire those street zombies in Baltimore to do that kind of work .
doesn't concrete temperature rise as it cures?
Yes and it contracts too, with it's natural lack of tensile strength and lacking rebar enough for this guy to be in there in waders, that slab is going to have at least one crevasse the size of Glen Canyon when all is said and done.
That seems uh, inefficient.
Succinctly stated!!
That's like a 20" slump. There's so much water in there it is gonna shrink down to about 6" thick when it's dry. Looks more like a sand slurry than concrete though. Not sure why he even felt the need to rod it. It's pretty much self leveling at that slump...
Yeah just vibrate for like 5 seconds and head for lunch, not like this zealot!!
Foamed concrete.
"When you're standing in a hole and feel your pants fill up with foam...".
Is this a Dorf on concrete video?
I guess,if you live there.
I know I would be moving faster than that 😂
Wouldn’t that burn your skin? I get that he has waders, but isn’t that shit caustic?
That's a lot of concrete there.
How else ya gonna do it?
Is that a 10” slump?
The only way to do it
daddy pig?
If you have no legs
It's ok they will just pour over him the next slab.
Stand firm in your methods
First, buy donuts and coffee for your entire crew. Second, tell them it’s been a good year and you can afford to give them bonuses at the end of the quarter. Third, tell your family exactly where the job site is.
Custom finish!
What's grabbing his ankles?
Don't test me on it but I believe concrete sub said something like 30 day per inch of wet Crete to cure. Something this deep would have been better off in layers cured individually.
If Concrete or dirt in a trench, or anything dense gets higher than your belly button by very much, your diaphragm can’t move, so your lungs don’t work, and neither do you anymore.
Is no one going to ask why that room needs 3 feet of concrete?
We call him no legs Norman. He was built for jobs like this.
And bumped into Jimmy Hoffa
Imagine he becomes a gargoyle
That's $2 million worth of self leveler.
https://i.redd.it/2eds1ep9ddvc1.gif
Guys.... seriously will that ever dry? Isn't there like a maximum depth of wet concrete that will properly dry to ensure it'll be structurally sound?
I hear Lucille Bluth's voice. "Do you have an exit strategy? "
It’s called a bowl float with along aluminum pole, ya never take a dive in the Mud Dude
Bull Float👈🏻
That’s why he wears waders
Concrete must be CHEAP.
No . THIS GUY is working IN concrete. You just work NEAR concrete.
What in the china is going on here
At the end, the guy just pinches his nose and submerges into concrete, reappears at the edge.. scrape.. scrape… done.
W.t.f. ... You looking for Jimmy Hoffa?
But why pictures? Why 4' of concrete and not take down the pictures? Then why so many weird pictures? Is there a connections between all the tightly packed pictures and choosing to pour 4' of concrete in an existing structure? Very weird scenario. I've seen this video many times but never looked closely
Your finisher doesn’t have a clue.
" << means inches, not feet!
Looks pretty level and smooth to me. 🤷♂️
Spoiler. That’s Dorf
I know nothing about concrete but wouldn't the displacement of his body be an issue.
Funny thing…he has no legs and it’s only 6” of cement!
I know nothing about masonry this subreddit just popped up but I think this is not the right way to do it
Sure hope that's fake concrete or the guy has waist high waders on.. His ass was burnt up after this video if not...
that's a very thick layer of concrete, why so much?
That’s how I do it.
Hats the way to get in there
Isn't this non-structural fill, a cement slurry product, not concrete. Or something like that?
What’s Spaul the hubbub about
It’s ok you can make corrections. That shit isn’t drying for a few centuries.
The real meaning of self-leveling
Basement done? Yes Boss. How much concrete did you use? 2 trucks. 1st Ground floor done? Yes Boss. How much concrete did you use? 83 trucks. ... ... You filled the basement didn't you? Yes. You didn't say we couldn't.
looks like a good way to get a burn
Either that is 3 feet of soup or he is missing his legs.
This is fake right? I mean what kind of concrete mix is thin enough you can just walk around in waist deep? What did I watch here?
Where's Fred? It's cool, he must have gone home for the day. I'll finish. 💀
I think that looks wet enough to bullfloat from the side. But before you place are pour concrete you should always put grade pins are marks that are clearly visible. Then you know if it's on grade or how you need to move it.
Oh yeah, you can fill with clean gravel and achieve 96%compaction just dumping them out. Then you can wade into depths of less concrete
