maybe water with a little cement dust in it but Concrete? How would the slump of that mixture even be rated?

Sure, it may flow and look like glass for now when he is done, but as it dries will there be bubbles from out gassing?

We have this in our house (we have hydronic heating - long runs of PEX pipe in the floor with a concrete top). The concrete is batch mixed on site, sand and not gravel. It is pumped into the house. It is called self leveling concrete.

I found one picture that showed the pour:


You can see how runny it is. It dries very smooth, no bubbles, not a hot mix from what I understand, but I don't know much more about it.

Seeing your I am wondering if some epoxy polymers weren't added to the mix to harden the final surface help seal it and prevent it from chalking. or was it sealed after curing?

There wasn't any epoxy that I saw. They had a mixer outside, bags of some type of cement, a pile of sand, and water.

The concrete was not the final floor. We have tile and engineered hardwood. Tile is glued down, the hardwood is interlocked and floats on a thin membrane. Also, there are no fasteners into the concrete - none anywhere. It is possible to find the pex it the heating system is running and you have a thermal camera, but if you poke a hole in the pex, that would be a nasty fix. If you need to fasten something down, you use the wall, not the floor.
