This study aims to develop a non-destructive and real-time technique tomonitor the chloride level at an early stage to prevent the development of the reinforcement’s corrosionusing electromagnetic spectroscopy. The experimental work was performed on 5 concrete specimenswith different chloride levels at three different concrete depths (18, 40, and 70mm) using the sensorsystem (2-12GHz frequency range) and a chlorometer. The LM algorithm was selected to develop aprediction model for the detection of chloride ions. The results demonstrated that the proposed techniquecan predict the chloride level with R2=0.986709 and RMSE =0.000120 at 5.42GHz. The resultsdemonstrate that the sensor can predict the chloride ion content across the range of the investigatedconcrete depths with the percentage error of 0.034% with respect to the accuracy of the chlorometer.
