In this research, compositional and processing parameters were varied to obtain zeolites‐containing geopolymers using mainly biomass fly ash wastes. In addition to curing temperatures, another primary factor affecting the typologies of the resulting zeolites was composition. The mixture composition used in the synthesis crucially affects the nature of the zeolitic crystalline phases in the geopolymeric matrix. Using 10 mol/L NaOH solution, faujasite‐type zeolites produced in geopolymers show a surface area of ~100 m 2 /g (BET), while those prepared by 8 mol/L NaOH solution have a much lower surface area of ~19 m 2 /g.
