Original Title

The Corrosion Status of Reinforced Concrete Structure Monitoring by Impact-echo method

English Title

The Corrosion Status of Reinforced Concrete Structure Monitoring by Impact-echo method

Type

Paper in proceedings (conference paper)

Original Abstract

The paper deals with the study of dominant frequencies of an Impact-Echo method response signal obtained from a reinforced concrete beam with a steel rod diameter of 8 mm. Tension pulse was produced in axis of the rod at one end and detected in axis at opposite end of rod. Dominant frequencies of the response signal will be the main criterions for the reinforced concrete rebar corrosion progress. The article presents the results of measurements obtained after 12 months controlled degradation in aqueous NaCl solution. The results were compared with measurements of electrical resistance of reinforcing steel by using the Thomson double bridge.
