Re: Green concrete

[dewline]

The project of inventing a process of climate-respectful cement/concrete(?) is certainly one worthy of investigation and investment on principle.

Absolutely, big of emitter carbon, and as the world gets richer, more populous and more urban there's going to be a lot of building materials needed.

A large amount of concrete is currently used where other materials could work just as well, with far lower emissions. If concrete's cost included emissions charges, then we'd go back to using actual stone for pavestones and curbstones, instead of molded concrete. Concrete would be saved for the applications where it is truly useful.

Undoubtedly true at the margin. I don't know how big that margin is. I wonder what the price (or more importantly overall cost) advantage of concrete over real stone is.
