Durability of Concrete – Civil Engineering Adda

2021-2-28  8. Carbonation Carbonation of the concrete is a process by which carbon di-oxide (CO 2) from the air penetrates into concrete and reacts with calcium hydroxide (Ca(OH) 2) to form calcium carbonate (CaCO 3) which results in a small shrinkage and affects the durability of concrete. There is another aspect of carbonation. Carbon-di-oxide is not reactive by itself but when it comes in ...
