title = "Using non-destructive testing methods for locating the steel reinforcement in reinforced concrete structures",
abstract = "Concrete cover for reinforcement steel is required to protect the steel rebar against corrosion and to provide resistance against fire. Determining the precise location, cover depth, and diameter of concrete reinforcement in existing structures can be rather difficult. Especially in densely reinforced elements, where there are several layers of reinforcement. The most common non-destructive methods for locating reinforcement are the electromagnetic cover meters and the ground penetrating radars (GPR) methods. This paper describes the possibilities of non-destructive determination of the location and depth of reinforcement in concrete structures using electromagnetic ProfoScope cover meter and GPR. The paper describes the use of the two methods for in-situ measurement of a steel-reinforced thick-walled concrete mock-up, presents the results of measurements of cover depth and the location of the reinforcement, and discusses the strong and weak points of the two methods. The results indicate that the cover meter is suitable for measuring the concrete cover depth while the GPR is very good in identifying and locating the rebar position in reinforced concrete structures.",
