Hello,
I would like to avoid additives in the concrete for our waterproof concrete basement (WU) as much as possible. I have heard different statements from various construction companies, ranging from "no additives are necessary" to "I cannot influence that, the concrete plant decides" and even "there's a lot of chemicals in it."
Are additives necessary, or can they be completely avoided? Can the construction company order a specific mix from the concrete plant, or do they have to accept whatever is currently being offered?
Thank you for your answers.

Hello,
So, if eco-friendliness is important to you, you might have to do without a basement...
Best regards,
Andreas

For our house alone, the CO2 emitted just from the cement in the concrete will be about as much as our so-called harmful gas heating system will produce over the next 15 years. Almost 10 years of that is due to the basement made from waterproof concrete and the basement ceiling.
cement production causes huge environmental damage (CO2 emissions you can hardly imagine -

Thank you for all the constructive comments.
Yes, we want to build in a healthy way, and frankly, I’m surprised that this is being met with so much ridicule here. I’m aware of what chemistry is, so there’s no need to explain that here.
I have read recommendations regarding healthy living that advise against additives in concrete. So far, I have not been able to find out exactly which additives these are. Terms like accelerators, retarders, and plasticizers have been mentioned. I was also told that you can’t say in advance because it apparently depends on the temperatures what is added. There is chemistry in every material.
Otherwise, it’s not ridicule if you choose, for example, a log house, but even then, nature is being destroyed and the materials are not transported ecologically. And for the foundation slab, you still need good old concrete.
