"In this study, an experimental research for estimation of slab depth, column size and location of rebar of concrete specimen isconducted using the Impact Echo (IE) method based on stress wave among non-destructive test methods. Estimation of slab depth had a total length of 1800 x 300 mm and six different depths, including 150, 180, 210, 240, 270 and 300 mm.The concrete column specimen was manufactured by differentiating the size into 300 x 300 x 300 mm, 400 x 400 x 400 mm and 500 x500 x 500 mm. In the case of the specimen for es timation of rebar, rebar of empty set 22 mm was used in a specimen of 300 x 370 x 200 and arranged at 130 and 150 mm from the top to the re bar top. As a result of error rate of slab, depth was overall mean of 3 .1%. Error rate of column size was overall mean of 1.7%. Mean error rate of rebar location was 1.72% for top, 1.19% for bottom and 1.5% fo r overall mean showing relative accuracy."
