Abstract
La présente invention se rapporte à un procédé pour la récupération des scories de haut fourneau, ainsi qu'à une installation pour sa mise en oeuvre. Le procédé est essentiellement caractérisé en ce que l'on introduit de la chaux fine dans la scorie liquide de haut fourneau, et en ce que l'on règle la composition du produit ainsi constitué pour qu'il se comporte comme un ciment Portland. Application à la fabrication d'une matière assez proche des ciments Portland et pouvant être utilisés comme tels.
