Using fly ash to partially substitute metakaolin in geopolymer synthesis

, 2014
Metakaolin-based geopolymers containing between 0 and 40% fly ash were prepared, to study the influence of fly ash substitution on the reaction process and products. At constant liquid/solid ratio, the partial replacement of metakaolin by fly ash reduces
