Closely watched means lowest bidder wins. Last year the Lafarge company released a new powderless ciment : it was great advance for lung health concerns. But it was 20% more expensive. Guess what kind of ciment I'm selling this year : the good old cheap stuff. Except for a few iconic architect houses, the end buyers just want a price. If we didn't have imposed quality regulations, we'd end up quickly like China with its low end school concrete... Good luck for the pricing.

How much more CO2 is required to make this alternative concrete? In the same way that ethanol fuel doesn't actually save fossil fuel oil (it takes a gallon of oil to make gallon (1.2 to be exact) of ethanol) this concrete may not actually be any better then the old stuff.

Moreover, I don't think anyone cares. Not only is there no price comparison, it does not mention how much extra effort was / is necessary to prepare this new concrete.
