Is statics material-dependent? Building with porous concrete T10

Hello,

I have a general question. Originally, we wanted to build with a Poroton T10.
The construction planning, structural analysis, and thermal insulation verification are therefore calculated with T10.

However, since we are having major problems with our construction company and want to part ways with them after the verification has been completed, and then award the trades individually,
the question for me is whether the structural analysis and the thermal insulation verification are tied to the brick.

In our construction area, about 80% of the shell construction companies build with aerated concrete, probably due to the easier handling and weight, I assume.
Since shell builders are currently unfortunately scarce here, I am wondering whether it is a good idea to approach the shell builder with Poroton. If they even submit an offer, it will certainly be inflated.

Therefore, the question is whether anyone has ever been in the same situation. Not necessarily including the construction company issue ;)
To my understanding, with the same compressive strength class and the same U-value, this should actually not be a problem, or am I wrong?

If U-Wrt and pressure resistance class are the same, it is relatively irrelevant. However, I wonder how one wants to comply with the energy saving ordinance using a T10.

If U-Wrt and compressive strength class are the same, it is relatively irrelevant. However, I wonder how one wants to comply with the Energy Saving Ordinance using a T10.

That would be great, are you sure about that? How the company complies with the Energy Saving Ordinance is relatively unimportant to me. But according to the Wienerberger homepage, the T10 is suitable for single-shell walls.

If U-Wrt and compressive strength class are the same, it is relatively irrelevant.

I wouldn't say that it is completely irrelevant. Even just a different stone thickness can lead to a different support of the concrete slab.

Of course, Steindicke must be the same. I wouldn’t want to build less than 36.5 cm either.

I am just too lazy to scroll back in your draft thread: are the walls on the upper floor above those of the ground floor?

whether it
is such a good idea to come to the shell builder with Poroton. If they even make an offer, a surcharge will certainly be added.

I always advise not to ask a red brick mason to do white masonry against his routine and vice versa. But I would rather fear complications due to lack of processing experience than expect a deterrent offer. The purchase prices for the bricks will not differ hugely.
