Original Title

Acoustic Testing of Reinforced Concrete Structure Corrosion

English Title

Acoustic Testing of Reinforced Concrete Structure Corrosion

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 the centre of the concrete beam and detected in opposite position of the concrete beam. 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 24 months controlled degradation in aqueous NaCl solution.
