ABSTRACT: The Remanent Magnetism Method (RM-method) is a non destructive method to identify poten-
tially un-safe conditions in pre-tensioned and post-tensioned concrete structures. The RM-method identifies
fractures in single pre-stressing wires, even when they are bundled with intact wires. Fractures produce charac-
teristic magnetic leakage ...
