APPARATUS AND METHOD FOR INSPECTING CONCRETE

PROBLEM TO BE SOLVED: To provide an apparatus and a method for inspecting concrete, whereby a concrete internal defect such as an internal crack of a concrete structure or the like can be efficiently, continuously and stably inspected anywhere. SOLUTION: This concrete-inspecting apparatus is comprises of a gear part formed of a metal and having plural percussion gears set at equal intervals to the circumferential face of a circular rotary body, and a handle part having one end connected to the rotary shaft of the gear part. Faces to be inspected are sequentially made to make percussion sound by the percussion gears when the gear part is rotated, while being pressed against the concrete faces to be inspected. The concrete internal defects are inspected from the change in sound.
