Metakaolinite was introduced to alkali activated slag mortars and pastes. Properties of fresh and hardened mortars as well as phase composition and microstructure of hardened pastes were investigated. Introduction of metakaolinite both as addition as well as substitution of slag results in severe decrease in strength of the mortars. SEM observations revealed, that metakaolinite presence results in much less compacted microstructure comparing to reference slag paste. The reason for that are differences in phase composition as determined with XRD. C-S-H phase formation is retained in the presence of metakaolinite and thus degree of hydration of slag is decreased comparing to reference, slag paste.
