Abstract

In the recent era, graphene oxide, a new member of the nanomaterial family, has grown in significance. In this study, River Sand (R-Sand) and Manufactured Sand (M-Sand) are being used as aggregate in cement mortars to assess the reinforcing impact of graphene oxide. The study examines effects of various graphene oxide concentrations on the compressive strength and flexural strength of the cement mortar’s mechanical and microstructural features. The study’s findings show how graphene oxide can be used as a reinforcing agent in cement-based products and how R-sand and M-sand perform differently when utilized as fine aggregate. The comparison of cement mortar with and without superplasticizer for both R-sand and M-sand is done once the optimal dosage of graphene oxide has been established. The work sheds light on the possibility of using M-sand as a substitution for river sand and the optimization of graphene oxide concentrations for maximal reinforcement in cement mortar. The optimal GO dosage for R-sand and M-sand was found to be 0.2% and 0.6%, respectively and it is validated through SEM tests.
