Carbonation of concrete

Although the deconstruction and demolition process at end-of-life can be comparatively brief, the resulting carbonation during this phase is significant. In addition to direct absorption of atmospheric CO2, the newly crushed concrete aggregate also undergoes carbonation as a consequence of leaching from exposure to rain; a process that has been shown to significantly increase the rate of carbonation.

Carbonation in Concrete with Recycled Concrete

2011-9-23  The phenomenon of carbonation of concrete results from the combination of several factors, such as the concentration of carbon dioxide that the structure is subjected to, the type of binders used in the preparation of concrete and the pore distribution of the hardened concrete. Besides the pore network of the concrete, the internal moisture conditions exert a determining factor for reactions to occur, as the pore must be partially saturated to provide a suitable environment for both the dissociation of CO

Carbonation of concrete

Carbonation is a slow and continuous process that progresses from the outer surface moving inwards. Over the lifecycle of concrete, carbonation will result in the reabsorption of around a third of the CO2 emitted when making cement, significantly reducing the whole-life CO2 footprint of both the cement and the concrete for which it is used.
