Abstract

Une composition servant à favoriser la déshydratation de laitier granulé comprend un surfactif anionique et un surfactif cationique en un rapport spécifié et, éventuellement, un agent antimousse. L'invention fournit également un procédé utilisant ladite composition qui permet d'obtenir, sans séchage à la chaleur, un laitier granulé ayant une teneur en hunidité ne dépassant pas 4 %. Application notamment à la fabrication du ciment.
