This study aims to verify a method for accurately estimating the sizes of the column, slab, and beam membersof concrete structures using the impact echo method, which is a nondestructive testing method. The concrete specimensare designed and fabricated with six single-layer frame specimens composed of columns, slabs, and beam members basedon three strengths of 24, 30, and 40 MPa. To estimate the sizes of the members according to the member types of concretestructures, the experiment was performed using the impact echo method. As a result of estimating the sizes of theconcrete column members using the impact echo method, the error rate is 2.9%. As a result of estimating the depth of theconcrete beam members, the error rate is 9.7%. And, as a result of estimating the thickness of the concrete slab members,the error rate is 2.4%. These results confirmed that quality control of the members of concrete structures is possible byestimating their sizes using a non-destructive testing method.
