Air-coupled ultrasonic test is a non-destructive test method for investigating damage in material. In this paper, reinforced concrete beams with one 8-mm diameter rounded bar were casted and tested under four-point bending test with water-cement ratio of 40% and 60%. The transducers were placed and...
