metakaolin as a partial pozzolanic replacement for cement in mortar and concrete has recently been presented by Sabir et al. [6]. Metakaolin is a thermally activated aluminosilicate material obtained by calcining kaolin clay within the temperature range 650– 800 _C [6]. It contains typically 50– 55% SiO2 and 40–45% Al2O3 and is highly reactive.
