Abstract

The construction industry is increasingly embracing sustainable materials, and geopolymer concrete (GPC) has emerged as a promising eco-friendly alternative to Ordinary Portland Cement (OPC). Derived from industrial by-products such as fly ash, GPC offers significant environmental advantages by reducing greenhouse gas emissions associated with conventional cement production. This study explores the monotonic and cyclic performance of fly ash-based GPC, with a focus on its mechanical and structural behavior. Key properties, including stress-strain relationships, load-deflection characteristics, flexural strength, modulus of elasticity, Poisson’s ratio, and tensile strength, are evaluated through comprehensive experimental testing. Reinforced GPC beams are subjected to both uniaxial compressive and cyclic loading to assess their performance under static and dynamic conditions. A comparative analysis with conventional reinforced concrete (RC) is conducted to evaluate the load-bearing capacities, failure mechanisms, and fatigue behavior of GPC beams. The study investigates failure modes and crack patterns, emphasizing the structural reliability and durability of GPC under varying loading conditions. Results highlight the unique response of GPC to cyclic loading, its energy dissipation capabilities, and its suitability for structural applications. Additionally, the findings underscore the potential of GPC in reducing the environmental footprint of the construction sector while maintaining structural performance comparable to traditional materials. This research contributes valuable insights into the mechanical properties of GPC and its application in reinforced structures, offering a foundation for the development of future design codes and standards. By demonstrating the viability of GPC in both static and dynamic scenarios, the study advocates for its broader adoption in sustainable construction practices.
