Abstract This paper investigates the effect of the solids-to-liquids S-L and Na2SiO3-NaOH ratios on the production of palm oil boiler ash POBA based geopolymer. Sodium silicate and sodium hydroxide NaOH solution were used as alkaline activator with a NaOH concentration of 14 M. The geopolymer samples were prepared with different S-L ratios 0.5, 1.0, 1.25, 1.5, and 1.75 and Na2SiO3-NaOH ratios 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. The main evaluation techniques in this study were compressive strength, X-Ray Diffraction XRD, Fourier Transform Infrared Spectroscopy FTIR, and Scanning Electron Microscope SEM. The results showed that the maximum compressive strength 11.9 MPa was obtained at a S-L ratio and Na2SiO3-NaOH ratio of 1.5 and 2.5 at seven days of testing. v View Full-Text
