DETECTION OF PRESTRESSED STEEL TENDONS BEHIND REINFORCEMENT BARS, DETECTION OF VOIDS IN CONCRETE STRUCTURES - A SUITABLE APPLICATION FOR RADAR SERVICES

Non-destructive testing as element of "quality-assurance" gains more and more importance in estimating the stability of old or damaged construction material. Radar technique, an electromagnetic testing method, can then be applied when continuous layers of different dielectric properties are to be detected within a construction unit. Location of prestressed steel tendons being reinforcement bars, as well as detection of voids in concrete structures, are typical examples for radar appliances in building engineering. Basics of this procedure, the use of it during "surveys" as well as examples of application, will be given. (A) For the covering abstract see IRRD 861706.
