Carbonatation - Wikipedia

Carbonatation is a slow process that occurs in concrete where lime (CaO, or Ca(OH) 2 ()) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate.. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5. This highly alkaline environment is one in which the steel rebar is passivated and is protected from ...
