Evaluation of Applicability of FRTP to Rebar in Concrete
Source abstract
Abstract
Though the thermosetting FRP (FRTS) is commonly used, its cost is very high and has not been widely used in actual structures. On the other hand, thermoplastic FRP (FRTP) can be mass-produced and the cost can be reduced. However few studies have focused on the use of composites with concrete. This study clarifies the applicability of FRTP made of carbon fiber or glass fiber to reinforcing bars in concrete. In the case of the FRTP rod alone, the tensile strength and elastic modulus before and after exposure to water at room temperature and before and after immersion in a highly alkaline aqueous solution were evaluated. In the case of FRTP rods and concrete complexes, the variations in the pull-out test were evaluated. Based on these results, we summarize the applicability of FRTP rods to concrete reinforcements. Finally, the bending strength of concrete beams with embedded FRTP rods was evaluated experimentally and theoretically.
