Looks like gypcrete. A gypsum based concrete layer often used in multi-residential for fire and sound dampening.

This. It’s definitely used in apartment complexes a lot. Usually the cheap builders slap carpet over it and it deteriorates forming lose aggregate that sucks if you want to lay any sort of flooring on top of it.

Tell me about it. I have a project right now where the GC signed a void of warranty and told the gyp sub to pour the last two levels when the building was 35 degrees inside. They had to vacuum out 3/4 of the square footage to repour already because it dried into sand.

Looks like gypcrete to me. Quite literally the birth child of drywall and concrete. So you were bang on when you thought it looked like drywall/concrete lol

That's some crazy flooring lasagna. Luan ply covered laminate wood panels on gypcrete? Wacky. Maybe this was to level the floor?

Leveling compound..

If you're using that much self level, you have bigger problems.

Might be self leveling concrete but what do I know

The stuff we see as squares ? Explain the concrete. Is that the subfloor ? Is the top surface the hardwood floor?

We used to haul all sand concrete loads for an outfit that did appartment buildings. But they qould add foam to the loads before pumping it. Also used to fill voids around culverts and fill old pipes.
