6.3.4.8 Carbonation Penetration Depth

The experimental campaign of Katz ( 2003 ) analysed the carbonation effect on
concrete for a conventional concrete and a concrete with recycled aggregates only.
For this study, and in order to collect the maximum amount of results, values
obtained in the three areas of the concrete specimen tested (top, bottom and sides)
were used. Like the resistance to chloride penetration, the carbonation penetration
