Abstract
The objective of this work was to determine the flexural behaviour of hybrid reinforced geopolymer concrete beam. Three Hybrid beam with varying GFRP-steel reinforcement ratios were fabricated and two other beams one with only steel and other with purely GFRP bars were also fabricated. The fabricated beams were employed to flexure test under four-point bending test set-up to evaluate strength and stiffness. The peak load, strength and deflection of each specimen was recorded. The flexural test of the hybrid beam revealed that the stiffness and strength of the decreases with decrease in total reinforcement ratio. It was also evident that the beam strength increases with increase in GFRP reinforcement ratio. A theoretical evaluation was developed to predict the flexural moment capacity of the beam. The theoretical evaluation showed that, the flexural capacity of the hybrid beam decreases with decrease in total reinforcement ratio of the beam. Flexural behaviour of beams with different GFRP-steel ratios was investigated in this research in terms of their stiffness, failure behaviour and strength. Conclusions are made according to the investigations done experimentally and analytically.
