UPV Method for Detecting Properties of Carbon-Nanofiber Concrete

Concrete is the most widely used construction material, and the addition of carbon-nanofibers (CNF) to concrete has many advantages in both mechanical and electrical properties such as higher strength, a higher Young's modulus, improved fatigue resistance in addition to self-monitoring behavior due to the high tensile strength and high conductivity. In this study, the Ultrasonic Pulse Velocity (UPV) method was used to characterize properties of concrete containing carbon-nanofibers. Concrete strength correlations between pulse velocity, electrical resistance variation and destructive tests were analyzed. The experimental results indicate that the compressive strength, pulse velocity and percent reduction in electrical resistance while loading concrete containing CNF are much greater than those of plain concrete.
