TLDR
In this paper, the authors present an experimental investigation concerning con- crete corrosivity and delamination effects on electromagnetic wave propagation in reinforced concrete bridge decks using ground penetrating radar (GPR).Abstract:
This paper presents the synthesis of an experimental investigation concerning con- crete corrosivity and delamination efiects on electromagnetic wave propagation in reinforced con- crete. It demonstrates that the data analysis procedure, proposed in the ASTM D6087 \Standard Test Method for Evaluating Asphalt-Covered Concrete Bridge Decks Using Ground Penetrating Radar (GPR)", is not always valid. A novel methodology of GPR data processing that allows the detection of areas of high probability of rebar corrosion in concrete is presented.read more

Methodology for Assessing the Probability of Corrosion in Concrete Structures on the Basis of Half-Cell Potential and Concrete Resistivity Measurements
TL;DR: A methodology for assessing the probability of corrosion in concrete slabs by means of a combination of two methods, that is, the half-cell potential method and the concrete resistivity method, is proposed and experimental results indicate that the proposed methodology can be successfully used to assess the probability.

Measurement of concrete resistivity for assessment of corrosion severity of steel using wenner technique
K. R. Gowers,Steve Millard +1 more
TL;DR: The Wenner technique is becoming increasingly popular for measuring resistivity of reinforced concrete to assess the rate of corrosion of the steel reinforcement once it becomes depassivated by chloride attack or carbonation as discussed by the authors.
