Flexural Response of GFRP-Reinforced Geopolymer Concrete Beams

The average compressive strength of the geopolymer concrete was 38.2 MPa. Based on the experimental results, all the tested beams showed nearly similar crack pattern, load-deflection response, bending-moment and deflection capacities, and strain readings, suggesting that the flexural response of a GFRP-RGC beam was not significantly influenced by the bar diameter; instead, by the properties of ...

Since the beams were made of different concrete mixes, the bending moment has been normalised by the factor b d 2 f c ′, where b is the width of the beam, d is the effective depth of the beam, and f c ′ is the compressive strength of the concrete mix. For the same deflection, BS1 and BS2 have a higher flexural capacity (until the yield strength) than the beams with the FRP bars. This is ...
