STUDY ON RUST DETECTION OF RC STRUCTURE BASED ON ELECTROMAGNETIC PULSED EDDY CURRENT

摘要

A set of rust detecting system for reinforced concrete was designed based on the electromagnetic pulsed eddy current (EPEC). The EPEC detecting test on the reinforced concrete specimens with different reinforcement diameters was performed. The finite element (FE) model was established. The results of the reinforcement position experiment show the Hall voltage peak value (HVPV) of the same lift-off value positively correlates with the reinforcement's diameter, and the HVPV declines fast with the increase of the lift-off value.
