Carbonation - an overview | ScienceDirect Topics

Carbonation is a phenomenon in which CO 2 in the atmosphere propagates into concrete to react with calcium hydroxide to form calcium carbonate, reducing the pH of the concrete pore solution down to 8.3–10.0. Once the pH inside the concrete is reduced, the stability of reinforcing bars buried inside the concrete is lost, and they begin to corrode.
