A new nanomaterial known as graphene oxide (GO) has been discovered, and it has the potential to improve the tensile and elongation properties of cement-based composites. In this study, the influence of the content of GO, say 0.01% increment upto 0.05% on fluidity of cement composites was estimated. In addition, the mechanical properties of GO-based cement composites, such as compressive, split tensile, and flexural strengths, are presented with respect to the content of GO to figure out its effect and to identify the right proportion. In this paper, the deformability studies of GO-based cement composites, such as the elastic modulus (E), are also presented. To further investigate the formation of a denser matrix, microstructural studies are also carried out in GO-based cement composites. New avenues for high performance cement composites are opened up by this important and extensive study. The results are revealed that the inclusion GO has shown reduced fluidity values as compared to control mix in all stages of hydration process. Results revealed that the optimum content of 0.04% of GO enhanced the flexural strength by 67.52% which is quite phenomenal. GO with 31.24% of oxygen helps improving the microstructure by enhancing the modulus of elasticity and toughness of the composite.
