Probabilistic Analysis of Reinforced Concrete Carbonation ...

Concrete carbonation relates to the diffusion of CO2 inthe atmosphere through the concrete pores and to the dissolution of the hydrates. A great deal of uncertainty still remains in this subject as a result of the random nature of the infiltration of these aggressive agents as well as the material and structural properties of reinforced concrete.

Carbonation of Concrete - In-depth Overview - Structural Guide

It is a process of reacting calcium hydroxide in the concrete with carbon dioxide in the atmosphere and creates a calcium carbonate and water. Ca (OH) 2 + CO 2 → CaCO 3 + H 2 O. This process starts with the concrete surface and it gradually moves towards the inner of the concrete. Carbonation of concrete is a slow and continuous process.
