This research investigates the impact of Graphene Oxide (GO) on the mechanical and durability properties of concrete with fly ash-blended cement, focusing on workability, setting time, compressive strength and abrasion resistance. Concrete samples were prepared with varying GO concentrations (0.04%, 0.08%, and 0.12%). The results showed that the addition of GO slightly decreased workability, with a gradual reduction observed, and increased the setting time, with the 0.12% concentration showing the lowest setting times. The 0.08% GO sample exhibited the best performance, with a 9.2% improvement in compressive strength, reaching 54.6 MPa, due to enhanced particle distribution and reduced micro voids. However, the 0.12% GO sample showed a slight reduction in strength, likely due to GO particle aggregation. The abrasion resistance tests showed that 0.12% GO provided the best durability, with a 17.02% improvement compared to the baseline (0% GO), demonstrating its superior performance against surface wear. These findings suggest that GO-modified concrete with fly ash-blended cement is suitable for fast-tracking construction projects and environments requiring high durability. Further research on long-term durability, microstructural interactions, workability optimization, and real-world field trials is recommended to validate the laboratory results and assess the broader applicability of GO-enhanced concrete.
