Abstract

Empty, segregation etc are the common internal defects of concrete slab, positioning the inner defects of slab is the basic requirement of the engineering detection and repair, in this study, the internal detects of concrete slab were studied based on the principle of impact echo method. Different forms and sizes of defects were set up within the concrete slab, testing with the impact echo scanning instrument, the plane position of the internal defects in the slab were intuitive by the generated 3d graphics. In the defective area, there are three obvious resonant frequency in the spectrum and the depth of the defect can be obtained by the corresponding frequency.
