Concrete is one of the composite and multiphase materials that the promising nanotechnology has penetrated a bit later in it. The properties, behavior and performance of the concrete depend on the nanostructure of the concrete and cement components. Indeed, the nanostructure of the constituents of the concrete leads to adhesion, cohesion and integrity. Adding nano-scale materials to cement can enhance its functional properties. Increasing the facility of concrete manufacturing process as well as the improvement of the final properties of hardened concrete are some advantages of the use of nano-materials in concrete technology. Indeed, nanotechnology eliminates the weaknesses of the concrete without creating drawback in other its properties. Research on the use of nanotechnology is ongoing to improve the mechanical properties of cement mortar and produce the concrete with modified properties. In this study, the Graphene oxide in nano scale is added into fresh concrete and its effect on of mechanical properties of concrete is investigated. The results of the research show that the use of Graphene nanoparticles in cement mortar and concrete structure significantly improves the mechanical properties and quality of concrete. Increasing the compressive and torsional strength and improving the thermal properties of concrete are some of positive effect of Graphene nanoparticles.
