I want to minimize my carbon dioxide emissions. The climate threat and all that...
Traditional cement involves very large carbon dioxide emissions. MgO-cement absorbs carbon dioxide from the atmosphere as it cures. Therefore, I would like to use MgO-cement instead of the old traditional CaO-cement.
It's not a big project, a foundation for a greenhouse. A good test project. It also means that I can afford to use a material that might be harder to find and possibly much more expensive without it being too painful.
Apparently, there have been attempts to introduce MgO-cement, but they seem to have failed. If you Google ceramicrete or NOVACEM, you find examples.
Does anyone know if it is possible to buy MgO-cement in Sweden? Or in neighboring countries?

Many see metal fever as a reason why MgO cement is not used very much.
Hm... "many"? Can you elaborate on that a bit?
I thought metal fever was only caused by very intense heating that produces fumes/smoke? Particles/dust are easily captured by a mask.
Ordinary cement is dangerous to inhale due to the risk of severe corrosion in the lungs or mucous membranes. So you should wear protective equipment when handling cement bags. For example, when pouring into the mixer.
As I understand it, there's not the same risk of corrosion with MgO-cement? Less dangerous?
But I'm not going to inhale it either...

there are no documents that I know of.Adoby said:
not many professionals wear a mask.
at least symptoms similar to metal fever.
have you checked how much carbon dioxide is in the manufacturing process?
check with companies that make melting crucibles if you can get tips there
But regular concrete also absorbs carbon dioxide.
This looks promising, henke_benke. It sounds like you know "many" people who, when they had the choice between using (and therefore being able to buy?) MgO cement or regular cement, opted for the regular cement. And you also seem to know people who, when they used (and therefore bought?) MgO cement, for some reason experienced symptoms similar to metal fever.
Could you ask any of these people where they bought the MgO cement? I am very encouraged by your information because it suggests that MgO cement can actually be found here in Sweden!!! Previously, I was worried that it might not be possible to get hold of.
Regular concrete absorbs carbon dioxide from the atmosphere as it cures. But much more carbon dioxide is released when regular CaO cement is produced. I think I've seen something about cement usage contributing roughly as much to global emissions as all flying.
MgO cement results in much lower total carbon dioxide emissions. This is perhaps the main argument for using MgO cement. That's exactly why I want to use MgO cement, even if it might be more expensive and harder to find.
Moreover, MgO cement is said to be less hazardous to handle and becomes stronger than regular CaO cement.
I have used regular cement multiple times before and have a cement mixer. But I now want to try something that is better than regular cement.
