Abstract

This research examines the potential in developing ground fly ash as a geopolymer material. Geopolymer mortar ground fly ash with constant liquid to ash ratio was used for testing radiant flow value. Effect of temperature, delay time of curing, concentration of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) to sodium hydroxide (NaOH) ratio on compressive strength were investigated. Test results showed that the workable flow of geopolymer mortar was in the range of 107-113% and was dependent on the ratio by mass of sodium silicate to NaOH and concentration of NaOH. The geopolymer mortar ground fly ash with high strength was obtained with concentration of NaOH of 15M (15Molar, 15M) with the sodium silicate to NaOH ratio by weight of 1.5. Using ground fly ash as a geopolymer mixture, the compressive strength was gained by leaving the sample for 1 h (delay time) before being put into the oven, and the optimum curing temperature was 65 °C in 1 day curing period.
