Zampieri et alii, Frattura ed Integrità Strutturale, 43 (2018) 90-96; DOI: 10.3221/IGF-ESIS.43.06 93 treatment mass drop measurements were conducted taking off the specimens from the tank and performing the following steps:  Cleaning of the tanks and replacing the solution with a new one; this operation was carried out to ensure that the corrosive liquid was as untouched as possible by external agents and to restore the quantities of water and NaCl lost due to evaporation;  Samples surface cleaning;  Samples weighing to measure mass losses. (a) (b) Figure 3 : a) Corroded specimens (672h); b) Mean mass losses interpolation of the corroded specimens (g/cm 2 ). In Fig. 3, the curve resulting from the interpolation of the mean mass losses (g/cm 2 ) measured every 168 hours is reported. As can be seen from the chart, the maximum mass loss at the end of the corrosion process is approximately equal to 0.06g/cm 2 .
