Abstract
(EN) A process for producing a pozzolan from a starting material. The starting material is size-reduced and incorporated into an aqueous slurry. The size-reduction can be carried out before or after incorporation into the aqueous slurry. Pressurized gas containing carbon dioxide is supplied to the aqueous slurry, and the aqueous slurry is mixed in the presence of the pressurized gas for a treatment period.
(FR) Procédé de production d’une pouzzolane à partir d’un matériau de départ. Le matériau de départ est de taille réduite et incorporé dans une suspension aqueuse. La réduction de taille peut être effectuée avant ou après l’incorporation dans la suspension aqueuse. Du gaz sous pression contenant du dioxyde de carbone est alimenté à la suspension aqueuse, et la suspension aqueuse est mélangée en présence du gaz sous pression durant une période de traitement.
