Research Abstract	A lot of concrete structures are deteriorating to dangerous levels throughout Japan. These concrete structures need to be inspected regularly to be sure that they are safe enough to be used. The inspection method of these concrete structures is typically the impact acoustic method. In the impact acoustic method the worker taps the concrete on the surface with hammer. So it is necessary to set up scaffolding to access vertical structures for inspection. However, setting up of high scaffolding is not economical in time and money. Moreover setting up scaffolding is difficult on very high concrete walls. So we developed a wireless remote controlled testing machine for Concrete Slab and vertical concrete walls using impact acoustic method and impact echo method.
