ABSTRACT
Geopolymer mortar is a material that has high SiO2 and Al2O3 content and has the
potential to be used as a base for making geopolymer mortar. This study aims to make
geopolymer-based mortar (POFA) and coal flyash with the addition of graphene, and
variations in the addition of graphene to the mechanical and morphological properties of
the geopolymer mortar. The preparation of the geopolymer mortar includes several
steps, namely the preparation and mixing of materials with various solid liquid ratios of
72:28, 60:40, and 80:20, then proceed with the preparation of an activator alkaline
solution (10 M NaOH + Sodium silicate) and the addition of graphene with variations of
0%, 1% wt, 2% wt, and 3% wt. The results of the morphological analysis showed that
the increased cavity that was formed increased along with the increase in the amount of
graphene added. While the results of the compressive strength test showed that the
highest compressive strength was obtained at 19,2 Mpa at a solid liquid ratio of 60:40
and the lowest compressive strength was obtained at 12,8 Mpa at a solid liquid ratio of
80:20.
Keywords: geopolymer mortar, coal fly ash, graphene, POFA
