Abstract:

Self-Compacting Geopolymer Concrete (SCGC) has gained attention as a low-carbon alternative to ordinary Portland cement, combining the flowability of self-compacting systems with the environmental advantages of geopolymer binders. This review synthesizes insights from 116 peer-reviewed studies, outlining progress in mix design, activator chemistry, curing approaches, and the use of additives and fibers to enhance performance. Although laboratory results consistently demonstrate promising workability, strength, and durability, several limitations remain. Long-term field evidence is scarce, mix-design procedures vary widely between studies, and many durability assessments rely on short-term or accelerated tests. Workability retention, structural behavior under real service conditions, and safety protocols for handling alkaline activators also require more systematic investigation. Emerging standardization efforts by ASTM, RILEM, and BIS indicate a shift toward clearer guidelines. Overall, SCGC shows strong potential, but broader adoption will depend on unified design methods, extended field validation, and improved safety guidance.
