The aim of this work is to provide confirmation of the possible use of two non-destructive techniques to detect damage of pre-stressing steel strands due to corrosion. For this purpose accelerated corrosion procedure has been conducted on these strands in laboratory conditions. Corrosion consequences were analyzed for various duration of accelerated corrosion process. The ultrasonic techniques and metal magnetic memory (MMM) method were used in this experimental study. The results show the application potential of ultrasonic techniques to analyze the effect of damage induced by accelerated corrosion on the nonlinear elastic behaviour of a steel strands. A new parameter, based on sensing of the magnetic field strength in the form of residual magnetization on the surface of the material, has been used in this study. Appraising parameters of measurement by the metal magnetic memory method were presented in the form of magnetogram – dependence of the magnetic field strength and field gradient on the measured distance. The changes of the magnetic field strength proved different stress concentration zones in the steel strands due to corrosion consequences. Subsequently, the differently corroded strands were subjected to tensile tests in order to determine their mechanical properties to verify and complement results of non-destructive tests.
