Installation, calibration protocol and data analysis of multi-electrode sensors embedded in concrete are proposed in this study. Measurements of resistivity are performed in a port wharf and analyzed in parallel with measurements of humidity, temperature, and evolution of the mechanical strength of concrete. The correlation between the evolution of the compressive strength and the resistivity, allows to validate the measurement protocol proposed. To visualize the distribution of resistivities in the studied volume, pseudo-sections of apparent resistivity were displayed. A methodology to plot and use them as an indicator of corrosion adapted to civil engineering structures is proposed. (C) 2019 Elsevier Ltd. All rights reserved.
