摘要

This study critically examines the contributions of the researchers’ contributions to geopolymer concrete (GPC) within the context of global research. The study covers key aspects including workability, strength properties, microstructural, and long-term durability behavior of GPC produced using fly ash alone and in combination with other agricultural and industrial by-products. The findings indicate that fly ash contain GPC shows comparable or superior strength and durability assessment to standard concrete, along with improved resistance to chemical degradation and a denser microstructure. The review also highlights the mix proportions, curing and concentration on the overall presentation of GPC. A unique contribution of this study lies in consolidating the researchers’ experimental results with existing literature to provide a coherent understanding of material behavior and optimization strategies for sustainable construction. In summary, the paper highlights the potential of fly ash–based GPC as an environmentally sustainable substitute for traditional cement-based systems.
