A slag cement mixture and process of making the same is disclosed. The slag cement mixture is composed of cupola slag and portland cement. The cupola slag is optionally ground granulated. One embodiment of the process includes rapidly quenching the slag by submersion into water or by spraying water onto it, and grinding the resulting product to achieve a fineness of at least 6,000 cm2/g. The process also includes the addition of 35 % ground granulated cupola slag to portland cement to achieve a stronger and harder cement than portland cement alone.
L'invention concerne un mélange de ciment de laitier et un procédé de fabrication de celui-ci. Le mélange de ciment de laitier est composé de laitier de cubilot et de ciment portland. Le laitier de cubilot est éventuellement granulé par broyage. Un mode de mise en oeuvre du procédé comporte les étapes consistant à tremper rapidement le laitier par immersion dans l'eau ou par pulvérisation d'eau sur celui-ci, et à broyer le produit obtenu pour obtenir une finesse d'au moins 6000 cm?2¿/g. Le procédé comporte aussi l'addition de 35 % de laitier de cubilot granulé par broyage à du ciment portland pour obtenir un ciment plus résistant et plus dur que le ciment portland seul.
