Metakaolin-based geopolymer; High-reactive bagasse ash; Compressive strength; Sodium silicate solution; Silica-rich sodium hydroxide


Geopolymer is a new material whose properties are similar to cement. Therefore, it is often used in the construction industry due to its high compressive strength. Geopolymers are made from aluminosilicate materials called pozzolanic materials such as metakaolin, fly ash, bagasse ash and rice husk ash mixed with a high alkali solution to occur geopolymerization, however, the agricultural ashes have limited reactivity. Since the pozzolanic materials had low reactivity for geopolymerization, the early compressive strength of geopolymer was low as well. Therefore, this research aimed to prepare the high-reactive bagasse ash by soaking the ash in sodium hydroxide solution to transform into silica-rich sodium hydroxide (SR-NaOH). In this study, the ratio of metakaolin and bagasse ash was 80:20 and the ratio of solid to alkali liquid was 1:1. The quantity of bagasse ash for SR-NaOH was varied as 0, 20 and 50%, mixed with 10M NaOH. The chemical properties were characterized including the functional group analysis by FTIR, the chemical compositions by XRD and the alkalinity test.  From the results, it was found that the usage of SR-NaOH with 50 percent of bagasse ash presented the highest compressive strength which was 2 times at 7 day age and 3.5 times at 28 day age higher than that of commercial NaOH.
