Guessing you didnt read it, because its in danish.
The article specifically mentions that this technique uses 30% of the material that would have been used for precast.

But what does that mean for strength? I also see surprisingly little “armouring”. Not sure how that’s called in English - the metal wires in-between.

I’m not sure about this company but there’s one in the US that has an embedded nozzle laying down steel cabling inside each concrete bead.

Rebar. Yes, there is no rebar and these houses are cracking and falling apart.

I’m just guessing, but it is probably reinforced with fiberglass or a similar fibers in the cement.

That sounds like a problem down the road. I get why people are pushing these. My perception is that there is another way entirely that doesn’t use so much energy (concrete is horrible in manufacturing and getting the resources): wood
Renewable High structures possible Light and therefore elements can be easily transported if you choose to prefab
Cheaper in material cost and labour because prefab is possible. Literally plopping down four elements and acrylic In the corners and you can move in)
right now it is mostly used as single family homes but larger prefab structures are coming.
