In this research paper, the effect of geopolymer concrete on the flexural strength and durability of reinforced concrete (RC) beams is explored, contrasting it with conventional Portland cement concrete. An environmentally friendly alternative to traditional concrete, geopolymer concrete uses industrial waste materials like fly ash to form a mixture of alkaline-activated aluminosilicates. This combination greatly reduces the carbon footprint of the concrete manufacturing process. For the purpose of assessing their mechanical performance, a total of 18 RC beams were cast, with 9 using geopolymer concrete and 9 using standard concrete, spanning different mix patterns. Geopolymer concrete beams outperformed conventional beams with flexural strengths of up to 29.4 MPa, as measured by three-point bending tests; the former had a maximum strength of 20.1 MPa, while the latter had an average of 20.4 MPa. Minimal weight loss and the lack of cracking were additional indicators of geopolymer concrete's exceptional resilience to high temperatures and chemical exposure, according to durability studies. These results demonstrate the improved mechanical qualities and longevity of geopolymer concrete, which raise its profile as a possible environmentally friendly building material. This work supports the idea that further research into geopolymer formulation optimization and long-term performance in different structural applications is needed to help build more sustainable infrastructure
