“…There are several methods for corrosion monitoring of RCS [1,[45][46][47][48][49][50][51][52][53][54], which, generally, are categorized as non-destructive methods (NDM) or destructive methods (DM). These methods allow the implementation of different methodologies with different degrees of complexity and cost, from which information on the progression and kinetics of corrosion phenomena can be obtained [55][56][57][58][59][60].…”

Several methods for corrosion monitoring of reinforced concrete structures (RCS) have been proposed in the last few decades. These systems may be used either in new, existing or repaired structures. The corrosion monitoring can be performed by different methodologies. These may or may not be destructive, use different degrees of complexity and cost, and provide information on the progression and kinetics of the corrosion phenomena. The destructive methods are limited to sampling. Therefore, these may not be representative of the whole structure, which is extremely important in RCS with large heterogeneities both in terms of materials used and in terms of the exposure environment. Within this context, non-destructive methods have been widely developed, which are intended to provide quick information about the entire structure. Ideally, these systems should be able to detect the corrosion state of the steel inside the concrete, the main causes of corrosion and the evolution of corrosion phenomena over time. This manuscript reviews and summarizes the actual state of the art and the main achievements in the field of electrochemical sensors based on non-destructive methods for corrosion monitoring of RCS in the last few years. The challenges and perspectives in this field will also be discussed.

“…The advantages of FBG sensor also make it a potential candidate for corrosion monitoring for structures. Lately, several attempts for applying FBG sensor in corrosion of steel rebar in concrete had been made [36][37][38], demonstrating that noticeable data shift would happen along with the corrosion growth [39,40]. Nevertheless, to date, limited sensing technologies can monitor the corrosion of structural steels with thermal sprayed metallic coatings due to the harsh environment during the thermal spraying process.…”

Metallic coatings using thermal spraying techniques are widely applied to structural steels to protect infrastructure against corrosion and improve durability of the associated structures for longer service life. The thermal sprayed metallic coatings consisting of various metals, although have higher corrosion resistance, will still corrode in a long run and may also subject to corrosion induced damages such as cracks. Corrosion and the induced damages on the metallic coatings will reduce the effectiveness of the coatings for protection of the structures. Timely repair on these damaged metallic coatings will significantly improve the reliability of protected structures again deterioration. In this paper, an inline detection system for corrosion and crack detection was developed using fiber Bragg (FBG) grating sensors. Experimental results from laboratory accelerated corrosion tests showed that the developed sensing system can quantitatively detect corrosion rate of the coating, corrosion propagations, and cracks initialized in the metallic coating in real time. The developed system can be used for real-time corrosion detection of coated metal structures in field.
