CONCRETE STIFFNESS MEASUREMENT APPARATUS AND METHOD USING ULTRASONIC WAVE IN THE UNDERWATER

摘要

A concrete strength measurement system and method using ultrasonic wave are provided to diagnose the safety rapidly in a non-destructive method by measuring the ultrasound transmission rate over the target concrete structure. A concrete strength measurement method using ultrasonic wave comprises a step of transmitting the ultrasonic wave to the inside of concrete by using a transmission transducer, a step of receiving the ultrasonic signal, which is transmitted to concrete, to a receiving transducer, a step of obtaining ultrasound transmission rate by dividing the distance between the two transducers by the detected time, and a step of storing the ultrasound transmission rate in a memory and displaying on a display panel.
