Abstract

La présente invention a pour objet l'utilisation pendant la fabrication du ciment d'une composition comprenant au moins un dispersant et au moins une molécule sacrificielle pour maintenir en partie ou en totalité les propriétés du dispersant, la composition étant sous forme soit d'une solution liquide, soit d'une émulsion ou soit d'une suspension; la quantité de la molécule sacrificielle dans la composition représentant au moins 5 % en masse de la masse de dispersant; et étant introduite avant ou pendant le broyage du clinker.
