Abstract | Geopolymer concrete reinforced with glass fibre reinforced polymer (GFRP) bars is a new and emerging technology that is suitable for the construction of corrosion resistant, durable, and highly sustainable civil infrastructures. To encourage its utilisation in the construction industry, a better understanding on its bond mechanism should be gained since it is the critical factor that controls the structural performance of reinforced concrete members. In this study, the bond-slip behaviour of 15.9 mm nominal diameter sand-coated GFRP bars with and without anchor head into geopolymer concrete, with a compressive strength of 33 MPa, was evaluated using direct pullout test. Three embedment lengths (5Ø, 10Ø, and 15Ø) were adopted to assess the interface bond between the GFRP bars and the geopolymer concrete. The results were compared to that of the pullout test of 16 mm diameter deformed steel bars embedded into geopolymer concrete. The results showed that as the embedment length increases, the pullout capacity of bond-slip specimen also increases. In addition, the GFRP bars have comparable bonding capacity to that of the deformed steel bars. Finally, the provision of anchor head increased the pullout capacity of the GFRP bar by as much as 31%. |
