What is Concrete Degradation Assessment via UPV about?

This study evaluated the degradation of concrete subjected to high-temperature heating by measuring ultrasonic pulse velocity. Concrete specimens with compressive strengths of 30, 70, and 110 MPa were heated to temperatures from 100 to 700°C and cooled to measure changes in mechanical properties and ultrasonic pulse velocity. Cracks generated during heating expanded after cooling, decreasing elastic modulus. Ultrasonic pulse velocity effectively measured crack formation and expansion, showing potential for
