Flexural Behavior of GBFS-Based Geopolymer-Reinforced Concrete Beams

چکیده
Geopolymer concrete (GC) is an emerging alternative construction material due to it being eco-friendly in production with considerably low carbon emissions. Despite material, the structural behavior of GC a rarely studied subject literature. The studies concerning mechanical members made from have established foundations its practical usability. current codes are exclusively for ordinary Portland cement (OPCC), and utilization these constitutes open question. In this study, 12 beams different shear span-to-effective depth ratios 2.5, 3.5 4.5 were manufactured tested three-point bending test setup. effect reinforcement ratio was also taken into account (0, 0.34, 0.45 0.67%). results compared predictive capabilities four two equations literature (all OPCC). addition, comparisons very limited number studies, which included tools strength GC. All specimens’ cracking moments calculated flexural tensile predictions experimental moments. Moreover, particularly that failed flexure, ultimate OPCC. It observed best moment could be by equation Diaz-Loya et al. (2011), resulted lowest coefficient variation (COV) consistently predicted on safe side, whereas, even lower COV, EC2 overestimated moment. For capacity, both ACI318 (2019) TS500 (2000) delivered relatively good employed confidently.
