The presented paper discusses the basics of application of magnetic flux leakage method in testing of reinforcement steel bars of post-tensioned concrete structures. Magnetic flux leakage method utilizes magnetic properties of reinforcement steel bars and influence of various defects on their magnetic properties. Currently, magnetic flux leakage method is mainly used to detect ruptures of reinforcement steel bars in concrete. The proposed method of processing of magnetic flux leakage signal allowed to reliably detect presence of corrosion and establish its position on a specimen. |
