Abstract
This study investigated effects of curing temperature on alkali activation of palm oil fuel ash. Compression test was conducted on samples activated with a mixture of sodium silicate and sodium hydroxide at different curing temperatures; ambient, 60 °C, 70 °C, and 80 °C. Also, XRD, TGA, FTIR, and SEM/EDX tests were performed to trace changes due to geopolymerization. Results showed that the ambient temperature can be applied to activate mixes with 100% POFA. Compressive strength of up to 36.8 MPa was obtained when samples cured at ambient temperature. The threshold temperature for activation of POFA was 70 °C.
