According to this PD0332991 table, for a constant W/GP solids ratio the compressive strength of the one part geopolymer mixture M5, containing the “Na2SiO3-Penta” activator as 1.5 wt% of the total geopolymer precursor, significantly decreased by 65% with respect to that of the mixture M4 containing the “Na2SiO3-GD” activator as 1.5 wt% of the total geopolymer precursor. However, the workability of the one-part geopolymer mixture M5 increased by 27% with respect to that of the mixture M4. Further, the density of both mixes was comparable. Hence, thorax can be concluded that in the case of using a combination of fly ash and hydrated lime as the geopolymer source materials, with all parameters being constant (i.e.
