• The velocity of ultrasonic wave in concrete is affected by elastic property or strength.
• This ultrasonic wave reaches to the receive transducer through concrete.
• Ultrasonic applies high voltage and sends it to transit transducer to generate ultrasonic wave.
• Ultrasonic measures the ultrasonic transit time accurately so it makes possible to evaluate a material or find an elastic properties nondestructively to investigate uniformity, cavities, cracks, fire/frost damage, delaminating, deterioration and strength.
• When elastic property or strength of concrete is high, the transit time is short. On the other hand, when the materials are contrary, the velocity is low.
• 52 khz concrete transducers which was designed to send and receive ultrasonic signal effectively in highly extenuative materials, including concrete, wood, stone and plastic.
