Are additives avoidable in concrete?

2020-04-23 08:29:38

Hi,

the environment is insanely damaged during the production of cement (CO2 emissions you can't even imagine -

Yep, that's pretty significant. For our house alone, the amount of CO2 emitted just for the cement in the concrete is as much as our so-called evil gas heating will emit over the next 15 years. By the way, almost 10 years of that is due to the basement made of waterproof concrete and the basement ceiling.
So if being eco-friendly is important to you, you have to do without the basement...

Best regards,

Andreas

If eco-friendliness is important to you, above all you must not build new. The rest is rubbish.

Better install a ventilation system. Substances that are not health-compatible are quickly removed from the house this way. I would not experiment with concrete and WU basements.

Healthy living is not the same as ecological.

Thank you for all the constructive comments. Yes, we want to build healthy to live in and frankly, I am surprised that this is met with so much ridicule here. I also know what chemistry is; there is no need to explain that here. I have read recommendations on the topic of healthy living, advising against additives in concrete. So far, I have unfortunately not been able to find out exactly which additives these are. Terms like accelerators, retarders, plasticizers were mentioned. I was also told that this cannot be said in advance because it apparently depends on the temperatures what goes in.

Chemistry is in every material. Otherwise, it is not ridicule if, for example, you choose a wooden log house, but even here nature is destroyed and not transported ecologically. And for the foundation slab, you still need the good old concrete.
