Experimental Study of Blended Binders with Metakaolin

Three metakaolins are evaluated for use as supplementary cementitious materials in cement-based systems. The vary mineralogical composition and fabrication (traditional flash calcination), but quite similar their surface area (16–19 m2/g), composition. Performance of metakaolin mixtures will be compared to two control (standard concrete foundation C40/50 high performance C60/75). In this study, the properties fresh mechanical durability hardened examined. rheological behaviour aimed determine effect on mixture workability. Compressive, tensile flexural strength elastic modulus measured at various ages. influence is assessed through rapid chloride migration carbonation measurements. For mixtures, drying autogenous shrinkage monitored creep measurements performed compared.
