Method for identifying the position of a crack in reinforcing steel

摘要

Method for identifying the position of a crack in reinforcing steel in a reinforced concrete structural member, the reinforcing steel being embedded with a known orientation in the concrete of the structural member directly or with a dielectric covering. The reinforcing steel is first magnetised, and the reinforced steel structural member then scanned along the extension of the reinforcing steel with a magnetisation measuring probe. Dipole formation due to remanent magnetism is determined as the criterion for the crack. IMAGE
