A system and method for treating unmarketable fly ash and improve its properties as an additive for concrete is disclosed. The method includes the steps of providing a gas stream containing ionized air (34), and an amount of fly ash (10) containing carbon having an adsorption capacity. The fly ash (10) is then exposed to the gas stream (34) to expose the carbon to the ionized air to promote the attachment of the ions to the carbon to reduce the adsorption capacity of the carbon.
L'invention concerne un système et un procédé permettant de traiter les cendres volantes non commercialisables et d'améliorer leurs propriétés en tant qu'additif pour béton. Le procédé comprend les étapes consistant à obtenir un flux de gaz contenant de l'air ionisé (34), et une quantité de cendres volantes (10) contenant du carbone possédant une capacité d'adsorption. Les cendres volantes (10) sont ensuite exposées au flux de gaz (34) pour exposer le carbone à l'air ionisé afin de favoriser la liaison des ions au carbone, pour réduire la capacité d'adsorption du carbone.
