Strength Measurements of Mortar with Voids Using Ultrasonic Pulse Velocity Method

초음파 속도법을 이용한 모르타르 내 공극의 강도 영향 측정

Ultrasonic velocity method is applied to measure and correlate the strength of concrete to the velocity of the ultrasonic wave. With voids inside, mortar specimens may show the lower strength and it is intended to detect such change using the ultrasonic velocity method in this study. The amount of voids was varied and the measured data represented the condition of the mortar with voids. The test results can be used to predict the strength of concrete with voids using ultrasonic velocity method.
