Flexural behaviour of concrete slabs reinforced with GFRP bars and hollow composite reinforcing systems

The study simulated rather aggressive conditions by immersing the hollow and solid GFRP bars rock bolts in the solution at different elevated temperatures 20 40 and 50 The experimental results showed that for a similar amount of reinforcement the GFRP bar reinforced hollow core polypropylene fiber concrete GFRP–HC–PFC specimen achieved 2 higher maximum axial load and 19 higher ductility than the GFRP bar
