Long-term durability investigations of two types of glass fiber-reinforced polymer (GFRP) bars, ribbed-type and sand-coated type, embedded in concrete elements exposed to a real-life marine environment at the KFUPM Beach, are in progress for a period of 10 years. Over 440 cubical and prismatic GFRP-reinforced concrete specimens, as well as bond specimens, are subjected to cyclic wetting and drying in the tidal zone. One set of specimens was retrieved after one year and tested for tensile strength, bond pull-out, transverse shear, and interlaminar shear to assess their durability. The retrievals or remaining specimens are scheduled at 3, 5, 7, and 10 years. This paper presents the plan for the long-term exposure of specimens in the sea and the results of the tests on the specimens retrieved after two years. First retrieval of the GFRP bar-reinforced specimens revealed that both ribbed-type and sand-coated type GFRP bars demonstrated good durability performance, with only minor degradation compared to the control specimens. These results provide an insight for long-term behavior of GFRP bars in harsh marine environments, though further exposure and testing are needed to assess performance over the full 10-year period.
