ᐅ Are additives in concrete avoidable?

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.

What do you think kind of harmful additives are included there? Usually, for a basement, at most some plasticizer is added, which is simply put, soap.

There is no vegan concrete.

Maybe build the house from trees and leaves??

Concrete involves chemistry, even without additives.

Whole grain cement, gluten- and lactose-free *LOL*

Fine dust. No, seriously: I agree with that question.
