This paper highlighted the shortcomings of Portland cement concrete and showed how geopolymer concrete can overcome those problems. It also investigated the flexural behaviour of three beams manufactured from rectangular hollow pultruded composite profile filled with fly ash based geopolymer concrete and tested under four-point bending. Their strength and stiffness are determined and confirmed with the Strand7 finite element simulation. The result of the experimental investigation and numerical simulations indicates the possible application of geopolymer concrete filled FRP beams in civil infrastructure.
