I'm not a concrete guy, done it a few times, but that's it. What would be the purpose for that thick of a pour?

That thick and no rebar cage. Strange indeed. And why are there pictures on the walls? And why is there an old man in their concrete? So many questions.

Biggest pair of concrete boots I've ever heard of. Sure as hell don't want him floating to the surface.

Makes little sense to me (not a concreter). The fluid pressure on his legs must be impressive.
Once he flattens that out he has to walk out, likely ruining everything he has flattened.
This is so crazy, I'm questioning if it is real.

This is definitely not a structural pour. It appears to me that someone is trying to cover up or hide something.
One country and one city comes to mind.

The term “slump” comes to mind.
The higher the water content of the mix the more it will drop as it dries.
This is not done to any code or standard I’ve ever seen.

A pour that thick without any rebar will definitely crack. Concrete curing is exothermic. Heats up quite a bit. A pour that deep will heat up a lot. And that will cause cracking. As for the soup they are calling concrete. Wow. Slump is a test done with a cone. About 8 inches at the base and 12 inches tall 4 inches at the pointy end. The concrete is poured in and the cone flipped and the drop in height is noted and compared against the desired consistency. So less slump thicker concrete. This stuff would be lucky to get an inch of height after it collapsed. A strong concrete like that would be near impossible to move through. You would vibrate it, let it partially set and then trowel it. All done with a lot of experience and proper timing.

I have seen other videos similar to this, my guess is some kind of floor leveler not concrete per say. Still many questions.

Seems like he is standing on some steps heading for the door otherwise how would he extract himself?

Well you want it to fill in behind this moron after he swims back out. You'd practically want it like water. But then he'll have to climb back in to use the screed. It's a never ending cycle.

I guess you could toss a vibrator in it for a few minutes then poll it out as soupy as that concrete looks it should level out like a mirror. if not just wait a few hours, "in this case maybe several" then trowel it out. What I wonder though is this fibered concrete. Due its seemingly obvious depth and lack of steel, being fibered would be the only thing that would make sense to me. We have no idea if they used plastizers (spelling)in it retardants. or accelerants in the mix either. The only thing I can say with any amount of certainty is without great care while it cures out the surface will chalk out on them.

You give them too much credit. There's probably two wheelbarrows, three trowels and a lawnmower in the bottom of that mess. Probably why that guy's swimming around. He's just trying to get his tools back.

Heck for all we know he could be a double amputee and the concrete is only 8 inches thick

I think you've solved it. That one got an audible chuckle out of me.
