An aqueous suspension suitable for use in the production of cementitious compositions which includes, prior to production of a cementitious composition, an aqueous medium and a particulate inorganic material suspended in the aqueous medium, the particulate inorganic material comprising metakaolin and being substantially lime-free and having a pozzolanic activity, the suspension having a Ph of at least 7.5, the suspension being in a stable form having a rheology which allows it to be flowable as a wet slurry and wherein the suspension includes a thickening agent which inhibits sedimentation of the inorganic particulate material in the suspension.
L'invention se rapporte à une suspension aqueuse pouvant être utilisée dans la fabrication de compositions cimentaires. Cette suspension renferme, avant la fabrication d'une composition cimentaire, un milieu aqueux et une matière inorganique particulaire en suspension dans le milieu aqueux. La matière inorganique particulaire contient du métakaolin, ne contient sensiblement pas de chaux et présente une activité pouzzolanique. La suspension se présente sous forme stable, possède un pH d'au minimum 7,5 et des propriétés rhéologiques qui lui permettent de s'écouler à la manière d'un coulis humide. La suspension renferme un agent épaississant qui empêche la sédimentation de la matière inorganique particulaire de la suspension.
