Textiles exhibit many advantages including high strength/weight ratio and high corrosion resistance. Therefore, textiles can substitute steels in textile-reinforced concrete (TRC) and can strengthen existing RC structures, such as textile-reinforced mortar (TRM), in coastal environments. However, there is a difference in the structural performance of TRC and TRM so that it is important to clearly distinguish the behavior of textile-based composites. In this study, the flexural performance, serviceability, ductility, and fabrication process of TRC and TRM were analyzed and compared via two separate application. The results of the experiments were expressed as indexes, which were compared with that of the reference RC specimen. Finally, an efficient method for applying textile-based composite structures in a coastal environment was considered in terms of flexural strength, serviceability, ductility, and fabrication process. The TRM composite exhibited unstable behavior after the yield stage. The TRC composite exhibited stable behavior in all the loading stages and showed higher ductility than that of the TRM composites. The results of this study are expected to aid in the selection of an appropriate application method for conducting intensive durability verification.
