Siporex floor structure

[Roobiiiiin]

I have bought a house built in 74.
The house is constructed with aerated concrete blocks as the floor structure between the basement and ground floor.
Never seen this before, is it common and what are the pros and cons?
It seems like there are thick blocks with chipboard on top.

Yes, it was common then, I have both floor joists and walls like this. Decent but not great insulation. There's not much to say about it, it's not a risk construction. Possibly it was made during some period of "blåbetong" but I'm a bit unsure about that.

I have bought a house that was built in 74.
The house is constructed with lightweight concrete blocks as flooring between the basement and the ground floor.
I've never seen this before, is it common and what are the pros and cons?

This type of flooring is unsuitable where it can be exposed to climate changes and moisture, which can cause the reinforcement consisting of tensioned steel wires to rust. In a residential house, there are no problems, except that without measures, you cannot make openings.

Yes, it was common then, I have both joists and walls in this way. Decent but not very good insulation. There's not much to say about it, it’s not a risk construction. Possibly it was manufactured during a period of "blåbetong" but I'm a bit unsure about that.

Okay, no mine isn't blåbetong.
Do you have any experience with laying tiles on siporex joists? Is it possible to float on top of it?
I've lifted up the floor in the hallway and it seems to be a thin masonite about 7mm, then under that some dark board that is 12 mm. Kind of like asphalt board.
