In this study, mechanical, physical and electrical properties of graphene oxide-containing mortars at nano scale were investigated. Graphene oxide was added to the crushed-sandy mortars prepared at constant water / cement ratio and cement content at 0.0, 0.5, 1.0, 1.5 and 2.0%. After gaining the strengths of the mortars, mechanical properties such as compressive strength, splitting-tensile strength and point loading strength were determined. As physical properties, water absorption by weight, capillary water absorption, apparent porosity and bulk density were obtained. In addition, the electrical resistivity values of the mortars were determined at different frequency values (0.1, 1, 10 and 100 kHz). According to the results obtained, it was observed that mechanical properties were increased considerably (44% in the compressive strength) especially when 0.5% of graphene oxide was added into the mortar. The changes in the physical properties were only at a low level, but only in the increase of the capillary water absorption. Significant increases were also obtained in the electrical conductivity values of the mortars due to the structural nature of the graphene oxide.
