Graphene oxide (GO)
Investigating the mechanical properties of high-performance concrete (HPC) employing mineral admixtures including fly ash, silica fume, and graphene oxide was the primary goal of this investigation. The HPC utilised in this study was created using regular OPC fine and coarse aggregate, portable water, and mineral and chemical admixtures such as fly ash, silica fume, and graphene oxide at varied replacement levels, in addition to super plasticizer. In compliance with IS 10262:2019, which calls for the use of HPC mix grade M60 with a w/c ratio of 0.33, super plasticizer was added to the concrete to increase its workability. In order to evaluate different mixtures, cube and cylinder beam specimens with extra mechanical and durability features were all cast. Partial cement replacements of 0%, 5%, 10%, and 15% composed of fly ash and silica fume, graphite oxide with a concentration of 0.04 % were used in the casting of M1 through M4, respectively. The concrete's mechanical behaviour, which was measured in terms of compressive strength, was then put to the test seven, fourteen, and 28 days after it was cast. The results of the tests demonstrate that including mineral admixtures usually improves the combinations' mechanical and durability attributes.
