Characterization of Fly Ash and Metakaolin Blend Geopolymers under Ambient Temperature Condition
View through CrossRef
Abstract
This paper presents a characterization of fly ash and metakaolin blend geopolymers of the optimize mix proportion of 10 M NaOH concentration mixed with the solid-to-liquid ratio of 1.2 and sodium silicate and sodium hydroxide ratio of 2.6. The combination of amorphous and crystalline phase in the fly ash (FA) and metakaolin (MK) blend geopolymers showed a positive effect on the resultant geopolymers. The formation of new crystalline phases which is sillimanite as presented by XRD analysis. Fly ash and metakaolin blend geopolymers showed the presence of geopolymer bonding at around 1390 cm-1 and 960 cm-1. This paper discloses effect of blending fly ash and metakaolin in the synthesis promotes the continual hydration of the geopolymers.
