| Abstract | The rapid growth of global infrastructure has intensified the reliance on traditional cement-based materials, leading to substantial $CO_2$ emissions and the exhaustion of natural resources. This research investigates the integration of eco-friendly construction techniques by evaluating reinforced concrete (RC) beams formulated with "green concrete"2 These mixtures incorporate industrial by-products—including silica fume, fly ash, and ground granulated blast-furnace slag (GGBS)—as partial binder replacements. The study employs a dual experimental and theoretical framework to assess structural parameters such as stiffness, flexural capacity, cracking patterns, and ductility. Laboratory specimens were subjected to two-point loading to establish load-deflection profiles and failure mechanisms5555. These results were validated through analytical limit-state design and nonlinear finite element analysis (FEA) using ANSYS. The findings indicate that green concrete beams offer structural performance comparable or superior to conventional mixes while achieving a 35% reduction in embodied carbon. A high correlation between empirical and numerical data ($R^2 = 0.97$) confirms the reliability of the predictive models, advocating for the use of sustainable concrete in structural applications. |
