Title
(EN) A NOVEL SUPPLEMENTARY CEMENTITIOUS MATERIAL AND PRODUCTION METHOD THEREOF
(FR) NOUVEAU MATÉRIAU CIMENTAIRE SUPPLÉMENTAIRE ET SON PROCÉDÉ DE PRODUCTION
Abstract
(EN) The present invention proposes a novel supplementary cementitious material comprising an activated mixture having at least an activated clay-based material and an activated calcium-based material. Said activated mixture is obtained by subjecting a mixture of at least a clay-based material and a calcium-based material together into an activation treatment till 70-95 % of said calcium-based material is activated; wherein amount of the clay-based material in said mixture is minimum 70% by weight of said mixture, where said clay-based material contains clay source of at least 40% by weight; and amount of the calcium-based material in said mixture is between 10-30% by weight of said mixture, where said calcium-based material contains calcium source of at least 50 % by weight. The invention further proposes a method for producing SCM and a binder containing a mixture of said novel SCM with cement.
(FR) La présente invention propose un nouveau matériau cimentaire supplémentaire (SCM) comprenant un mélange activé comportant au moins un matériau à base d'argile activé et un matériau à base de calcium activé. Ledit mélange activé est obtenu en soumettant un mélange d'au moins un matériau à base d'argile et d'un matériau à base de calcium ensemble à un traitement d'activation jusqu'à l'activation de 70 à 95 % dudit matériau à base de calcium ; la proportion du matériau à base d'argile dans ledit mélange étant au minimum de 70 % en poids dudit mélange, ledit matériau à base d'argile contenant une source d'argile à au moins 40 % en poids ; et la proportion du matériau à base de calcium dans ledit mélange étant comprise entre 10 et 30 % en poids dudit mélange, ledit matériau à base de calcium contenant une source de calcium à au moins 50 % en poids. L'invention propose en outre un procédé de production de SCM et un liant contenant un mélange dudit nouveau SCM avec du ciment.
