Effect of mixing metakaolins: Methodological approach to estimate metakaolin reactivity
Ceramics International, 2023 International audience ; Geopolymers are obtained from an alkali silicate solution and aluminosilicate sources. The source commonly used geopolymer is metakaolin. The chemical composition, extraction site or calcination process of metakaolin influence its reactivity and thus the properties of the consolidated samples.
