The flexural properties of eight 200 x 300 mm (8 x 12 in.) concrete beams reinforced with basalt fiber-reinforced polymer (BFRP) reinforcing bars were investigated. The beams were reinforced with four different sizes of BFRP (10, 13, 16, and 25 mm). The flexural reinforcement ratios ρf ranged from 1.43 to 10.70 times the balanced ratio ρfb.
