| description | This study investigates the influence of graphene on the electrical conductivity and mechanical properties of concrete composites, aiming to develop advanced materials for structural applications. Graphene’s exceptional electrical conductivity can significantly enhance inert concrete matrices by forming a conductive network. Concrete samples were prepared with minimally oxidized graphene (MOG) at 0.2 and 0.5 % by weight of cement. Spectroscopic techniques, including Raman and infrared spectroscopy, were employed to characterize the interaction between graphene and the cement matrix. Results showed that the addition of MOG reduced electrical resistivity, with the 0.2 % sample decreasing from approximately 600 to 550 Ohm under compression. The yield point was around 40–50 kN, with a sharp decline in resistivity at this load. Compressive strength tests indicated a 48 % increase in strength with just 0.05 % graphene oxide. These findings suggest that graphene incorporation enhances both electrical conductivity and mechanical strength, making the composites suitable for applications in structural health monitoring and self-heating systems. |
