I would like to avoid concrete additives for our concrete basement. Now I've heard different statements from different construction companies, from "you don't need any additives" to "I can't influence it, the concrete plant does it" to "there are a lot of chemicals in there".
Are additives necessary or can we do without them altogether? Can a construction company order the mix from a concrete plant or should they just use what's mixed in the proposal?
You probably want to use healthy building materials. It doesn't matter if it is an "additive" or not. The reference to "it contains chemicals" is completely undifferentiated. There are chemicals in our intestines as well.
