Carbonation of concrete

Concrete carbonation Over time, CO2 in the atmosphere reacts with the calcium oxide in concrete to form calcium carbonate; a process called carbonation. This is essentially a reversal of the chemical process that occurs when making the cement used in concrete i.e. the calcination of lime that takes place in cement kilns, which accounts for the majority of concrete''s embodied CO2.
