Abstract
Basalt fiber has many advantages as a reinforcing fiber such as high tensile strength and similar density to concrete. This study investigated the bonding property and the effect of fiber orientation on tensile strength of basalt fiber. Single fiber pullout tests for basalt and polyvinyl alcohol (PVA) fibers were performed to evaluate the bonding property between basalt fiber and mortar. And then tensile strength of basalt, PVA, and polyethylene (PE) fibers according to fiber orientation were measured. From the test results, it was exhibited that the chemical bond, frictional bond, and slip-hardening coefficient of basalt fiber were 1.88, 1.03, 0.24 times of PVA fibers, respectively. And the strength reduction coefficient of basalt fiber was 9 times of PVA fiber and 3 times of PE fiber.
