Effect of reduced graphene oxide on mechanical properties of concrete

M40 grade concrete’s balanced strength and endurance make it a popular choice for structural applications. The usage of nanoparticles to enhance the characteristics of conventional concrete has increased recently due to the need for high-performance and sustainable building supplies. Concrete’s strength and microstructural integrity may be improved by reduced graphene oxide (rGO), a nanomaterial with unique mechanical and chemical properties. The impact of rGO on the mechanical characteristics of M40 grade concrete that contains Alccofine as an additional cementitious ingredient is assessed in this study. The effects of four varied rGO dosages (0.015%, 0.03%, 0.045%, and 0.06% by weight of cement) on flexural, tensile, and compressive strengths were evaluated. Studies show that, up to an optimum dosage, adding rGO to M40 concrete greatly improves its mechanical performance; after that, the advantages decrease. The potential of rGO as a useful nanomaterial for enhancing the functionality of traditional concrete in structural applications is highlighted by this investigation.
