Abstract:

Although geopolymers can significantly reduce carbon dioxide emissions, their widespread application is limited due to the requirement for alkaline activation solutions. The recently developed “one-part geopolymer” overcomes this limitation by using a solid alkaline activator, thereby enhancing construction convenience while maintaining performance comparable to conventional alkaline solution activated geopolymers or cement-based materials. In this study, a split Hopkinson pressure bar (SHPB) was employed to investigate the dynamic properties of one-part fiber-reinforced geopolymer concrete (OP-FRGC), focusing on different types of fibers. The compressive dynamic increase factor (CDIF), energy absorption capacity, and failure modes of OP-FRGC under dynamic loading were analyzed. The results indicate that the incorporation of fibers changes the failure mode of OP-FRGC from brittle to ductile, significantly enhancing its toughness. OP-FRGC exhibited strain rate sensitivity, with the CDIF showing an approximate logarithmic increase with the strain rate. In addition, a comprehensive evaluation of OP-FRGC incorporating different fiber types was conducted, considering mechanical properties, sustainability, and cost. This study offers a useful reference for understanding the dynamic behavior of OP-FRGC, thereby promoting its potential in practical engineering applications.
