APPARATUS AND METHOD FOR NON-CONTACT MEASUREMENT OF CONCRETE STRENGTH ULTRASONIC WAVES

摘要

The present invention relates to a contactless concrete intensity measuring device using ultrasonic waves, capable of decoding the intensity of concrete by calculating the propagation velocity of a surface wave, flowing along the surface of the concrete, by installing an ultrasonic receiving transducer and an ultrasonic transmitting transducer at a distance from the surface of the concrete. According to the present invention, the device includes: a support structure installed on a side of the concrete; an ultrasonic transmitting transducer installed in the support structure to be at a distance from the surface of the concrete to generate ultrasonic waves in the concrete; an ultrasonic receiving transducer installed in the support structure to be at a distance from the surface of the concrete to measure ultrasonic waves propagated through the concrete; and a controller decoding the intensity of the concrete by using a detection signal of the ultrasonic receiving transducer.
