I can see that concrete can really go bad after a few hundred freeze and unfreeze cycles:
If an ICF house has insulation from the inside of the house, then the concrete will be cold, if the outside temperature is cold too.
More detail on the layers: insulation for the ICF is grey EPS, 15cm outside, 15cm concrete, inside: 5cm
The question: for how many years can concrete survive without any issue in an ICF house?
I think, because of the 5cm grey EPS insulation from inside, the concrete will receive many freeze/unfreeze states and will go bad earlier/deform/crack?. Living in ~eastern EU, winters are max -10C. But it goes about ~60 days under 0C yearly.
