| Summary: | With the development of nanotechnology, nanomaterials have been known to have the
ability to improve the strength of geopolymer. Recent findings have indicated that
incorporation graphene nanoplatelets (GNPs) as a nano-filler can be used as an
additive to improve the mechanical properties of composites. Therefore, the effects of
the addition of graphene nanoplatelets (GNPs) on the mechanical properties of a fly
ash based geopolymers were investigated. Six different geopolymer mixtures were cast,
cured, and tested to determine their compressive and tensile strength. Before adding
the GNPs into the mixture, it was dispersed in water with ultrasonication treatment to
ensure the excellent bonding effect with the mixture. With the incorporation of GNPs,
the results showed better mechanical properties where the addition of 0.3% of GNPs
increased the compressive strength by 18.62 % and tensile strength by 13.55 %. Hence,
with the optimum addition amount of graphene, the strength of geopolymer can be
increased which eventually helps to achieve the long-term durability of structures. |
