It explains why one material has so many different purposes and functions. Carbonation occurs gradually in concrete as CO2 in the air reacts with cement to form water and calcium carbonate. Concrete, on the other hand, is a relative newcomer (at least in the sense that is under dispute). So there you have it! All rights reserved.
