For fly ash, the soluble crystals are mainly quartz (SiO 2), while mullite and Al 2 O 3 are inert substances under alkaline conditions. Therefore, the total amount of soluble elements is calculated using the amount of Si and Al in the amorphous phase and quartz (SiO 2), as shown in Table 2. For metakaolin, as it only contains inert mullite, the ...
