Radar-based Quantification of Corrosion Damage in Concrete Structures

摘要

The ground penetrating radar (GPR) methods has been found to be useful in evaluating the corrosion damage in the concrete structures. However, the GPR image is very difficult to be interpreted because it requires processing technique. This paper studies the GPR to detect the corrosion of concrete structure using image processing technique. The reinforced of concrete slabs are corroded as results of impressed current method to accelerated the corrosion. The GPR are used for detection the corrosion damage in the concrete slabs. The GPR data showed that the corrosion can be detected, however need to analyzed and interpretation by using image processing and discriminant analysis. Image processing technique is applied for quantification of corrosion data while discriminant analysis is applied to classify the data.
