Unraveling the flexural behavior of concrete and compare with innovative fea investigations

Modern structural issues require multi-functional concrete, and demand for it is enriched. The advancement of nano engineering technology plays a major role in the cementitious materials namely flyash, silica fume and
graphene oxide. In this research varying percentages from 0 to an increment of 0.01% upto 0.05% of graphene oxide and 20% of flyash and silica fume together is used by weight of ordinary Portland cement to obtain high strength. To unravel the complex flexural behavior of concrete structures by integrating static load tests and the best mix is compared with advanced Finite Element Analysis (FEA) techniques, specifically utilizing ANSYS. The study investigates the structural response under static loading, focusing on vital parameters such as load deflection, ductility factor, stiffness factor, energy absorption capacity, and energy index. The examination of these factors provides comprehensive insights into the material's deformation characteristics and resilience in flexural conditions. The incorporation of innovative materials fly ash, silica fume, and graphene oxide into the concrete matrix are potential to enhance concrete properties, and their impact on flexural behavior. The 0.04% of graphene oxide is superior in all aspects flexural behavior and it is compared with FEA model (ANSYS).
