“ Concrete continues to set and cure for months and years, increasing its strength over time. It's a long-lived giant chemical reaction that continues on long after it has set.”

- beaner 6y agoBut it continues to take up the same volume of space, so isn't there a limit to how much carbon dioxide it can remove from the atmosphere and store?
- krisoft 6y agoYes of course it has a limit. Nobody said that it is an infinite sink. If you are interested in the details I can recommend J.P. Severinghaus et al., “Oxygen loss in Biosphere 2“.
- beaner 6y agoI'm just surprised because somebody said that the concrete soaked up so much carbon that the trees alongside it in the biosphere were unable to grow. That sounds like a lot of carbon. Like, a lot. I'd expect that it would have to absorb enough carbon that it could displace some amount of the volume that it would have appeared as in tree form. Can you fit a third of a small forest into the concrete around that small forest? It seems unlikely.
