The Role of Metakaolin Fineness on Rheological Properties of Cement Pastes

Abstract:

Viscoelastic properties of Portland cement-metakaolin fresh pastes were measured using rotational rheometer. In mixtures 10 % of Portland cement was replaced by various fractions of metakaolin with different particle size distribution. The role of the fineness of metakaolin was revealed characterizing flow, adhesion and creep of the fresh pastes.
