I'm going to prepare fly ash/slag based geopolymer mortars, so i need optimum mix design for achieving high compressive strength and other better mechanical properties.
Would you mind sharing your experience for me?
Sincerely, Milad
After reviewing many papers, i found that 0.35 Al/Bi ratio, 10-12 M NaOH and 1.5-2.0 SS/SH ratio and 80-100 C heat curing for 24 hours.

I appreciate for sharing your data, but i couldnt understand the Al/Bi ratio, what is the Al and Bi? Bi=binder?
Al/Bi stands for alkali to binder ratio and SS/SH stands for ratio between sodium silicate and sodium hydroxide.

I hope the above papers will give the ideas you need for a successful investigation.
