AQUEOUS SUSPENSIONS OF METAKAOLIN AND A METHOD OF PRODUCING CEMENTITIOUS COMPOSITIONS

摘要

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.
