Abstract: The purpose of this study is to estimate the early age compressive strength of concrete members and the thickness of concrete column members using the ultrasonic pulse velocity method and impact echo method among nondestructive test methods. A nondestructive experiment was conducted by making 6 furniture-type specimens comprised of columns of different thickness and size and 90 specimens of 6 age variables. For concrete specimens, the design parameters were set at 16, 20, 24, 48, 72 and 120 hours at the age of 24, 30 and 40 MPa. The possibility of using the early age compressive strength and size of the concrete members as a quality control technique was confirmed based on the correlation between the compressive strength and pulse velocity in the ultrasonic pulse velocity method and impact echo method. Therefore, the validity of the nondestructive testing method as a quality control technique for concrete structures was confirmed.
