Abstract
This paper presents the durability test results of various commercially available composite rebars and tendons. The durability of eight different combinations of glass fiber reinforced plastic (GFRP) rebars, as well as, two carbon fiber reinforced plastic (CFRP) tendons, and one aramid fiber reinforced plastic (AFRP) tendon was examined. Tendon and rebar specimens were directly exposed to seven different solutions simulating accelerated exposure to various field conditions. Test results indicated long-term durability problems associated with GFRP rebars, while CFRP and AFRP tendons displayed excellent durability in harsh environments. The free-phase model (i.e. Fick's law) of diffusion showed to be an acceptable model to approximately predict the losses in tensile strength of composite rebars and tendons.
