reinforcement bars - Opis:
- It is known that sub-surface discontinuities of matter, internal voids, inclusions of other materials or delaminations of the structure can be revealed on the surface temperature distribution. An important element of IR thermography investigations is the application of an appropriate heat source to heat the examined object. This article discusses the use of eddy currents for identification of reinforcing bars in concrete samples. The experiments have the laboratory character and are used primarily for qualitative assessment of the influence of bar diameter and concrete cover thickness on the identification of reinforcement in concrete elements. In order to induce a transient heat flow in tested samples, the eddy currents (EC) generator from IFF GmbH was used. After the pulse was completed, the surface temperature distribution was recorded using FLIR T620 infrared camera. The following experimental studies validate the practical application of active IR with EC to locate and assess the technical condition of reinforcing bars in reinforced concrete structures in buildings and civil engineering structures.
