Monitoring of Reinforced Concrete Structure Corrosion by Using Impact-Echo Method

Abstract:

This study deals with frequency inspection of response signal which was obtained from a reinforced concrete beam. Impact-Echo method was used for finding the dominant frequency which is the main criterion for condition assessment of reinforced concrete. The results of acoustic method were compared with measurements of electrical resistance of reinforcing steel by using the Thomson double bridge. The concrete beam with a steel rod diameter of 6 mm was tested. Tension pulse was produced in the centre of the concrete beam and detected in opposite position of the concrete beam.
