Ultrasonic Pulse Velocity Evaluation of Concrete During Heating

In this study, the ultrasonic pulse velocity of the concrete cooled to room temperature after heating and the concrete during heating were evaluated. Also, the ultrasonic pulse velocity and mechanical properties of concrete were compared. As a result, the ultrasonic pulse velocity decreased when the concrete degraded during heating, and the ultrasonic pulse velocity of the cooled concrete decreased significantly. Which is consistent with the deterioration of mechanical properties of concrete.
