Something which was mentioned in Season 2, Episode 2 "Story of a Gun" of CSI:Vegas. Which is what the refusers of the green were referencing.

However it's one the more exciting developments in attempts to reduce Greehouse Gas (ghg) from the construction industry. Using the Carbon Dioxide produced during Cement Production as an alternative to Ammonia in curing the Concrete that much of that Cement is used to make.

Of course if I were to lay a Concrete foundation in preperation for a new wall. I would have to find a way to stop the Foxes putting their noses and paws in it. In the several days it takes to dry and several weeks it takes to cure.

Fortunately Foxes hate the smell of Ammonia.

Another alternative is getting a pre-made Concrete slab.

Although have you ever tried lifting a 10,000mm Concrete slab on your own?
