N2 - This paper investigates the influence of flyash (FA) and crystalline admixtures (CA) on the rheological properties of graphene oxide (GO) infused cement paste. GO, which is a nano-sized particle when incorporated into concrete improves its mechanical, and durability properties, making it more a sustainable choice. GO, being hydrophilic in nature, reduces the workability and fluidity of concrete significantly. Past studies show that the use of FA and CA improves the viscosity and fluidity of the concrete mix, with a better strength and durability performances. This study aims to determine the optimal combination of these materials to achieve desired rheological characteristics. Various dosage combinations were studied: GO at 0.02, 0.04, and 0.06%; FA at 5, 10, and 15%; and CA at 0.5, 1, and 1.5% by weight of cement. Results revealed that the combination of 10/15% FA and 0.02% GO yielded optimal rheological properties, enhancing the fluidity, and reducing the plastic viscosity. GO initially reduces the fluidity however concentration beyond 0.4% dosage improves the fluidity. 0.4% GO dosage shows poor fluidity and flow ability in all the mix combinations. The findings highlight the potential of FA and CA to mitigate the negative impacts of GO on cement paste rheology, offering valuable insights for designing high-performance concrete with improved workability and durability.
