Piégeage de CO2 dans des granulats de béton de démolition (Carbonated Recycled Aggregates for Concrete) – CRAC
The objective of this research project is to capture carbon dioxide inside crushed demolished concretes. The higher specific surfaces of these crushed concretes could allow for a far higher CO2 capturing speed via carbonation reactions than when the material is still part of a wall or a slab. The CO2 capture will moreover allow for an increase in the quality of the recycled aggregates formed by these crushed demolished concretes. Their porosity will indeed decrease whereas their chemical stability will increase. A part of the growing quantity of demolished concrete could therefore be used to prepare new concretes instead of being used in low grade applications such as road bases.
