Concrete slab from the 70s // blue lightweight concrete?

[Globetrot]

Hello,

Is there a risk that blålättbetong was used for casting floor slabs in the 70s?
...or was it only "prefabricated wall elements" that blålättbetong was used for...

:x

Never heard of plattapåmark cast with lättbetong!

The "Blåbetongen" I have seen has been used to build walls. The slab is cast from concrete, you can probably safely assume that.

Check if you can borrow a Geiger counter from the municipality's environmental office so you can measure yourself which parts are and which aren't blåbetong.

The house is now bought, and we borrowed a Geiger counter from a friend; it was not blå lättbetong.
