Geopolymer Cement Based on Alkali Activated SlagGeopolymer Cement Based on Alkali Activated Slag
, 2021 The aim of this investigation is to prepare geopolymer cement by mixing various amounts of granulated blast furnace slag (GBFS) with Fly ash (FA) and cement kiln dust (CKD). Seven blends are prepared using 100 % slag , 95% slag+5% CKD or fly ash , 90% slag + 10% CKD or Fly ash and 85% slag + 15% CKD or Fly ash .
