Hello!
I live in a blue concrete house from the early '60s.
As we renovate, I'm taking the opportunity to tear down and set up new wood-framed walls. I've been tearing down section by section and framing new ones before continuing to tear down, with consideration for any load-bearing parts. I've heard from several sources that I'm being overly cautious since blue concrete shouldn't be load-bearing.
On this forum, there are a number of threads asking for advice on tearing down potentially load-bearing blue concrete walls. My question then, as the title suggests, is there any relevance to what I've heard that blue concrete shouldn't be load-bearing?

"One such building material is blåbetong, which was manufactured between 1929 and 1975. This building material was used in small houses, both in exterior walls and in load-bearing and non-load-bearing interior walls as well as in floor structures."

"Demolishing blåbetong walls can be a suitable alternative if it is a matter of non-load-bearing partition walls. This is an intervention that is sometimes done in connection with renovations when larger repairs are being made. The partition walls can then be replaced by, for example, framed walls with plasterboards. In this way, the radon emission to indoor air can also be significantly reduced, as the partition walls emit radon from two sides. Removing exterior walls or load-bearing interior walls of blåbetong involves significantly greater interventions in the house and is hardly justified."
