Non-steady-state chloride diffusion coefficients obtained from migration and natural diffusion tests. Part I: Comparison between several methods of calculation

摘要

The calculation of non steady state chloride diffusion coefficients by migration tests is a quite controversial subject due on one hand, to the complexity found in describing the penetration of chlorides and on the other hand, to the fact that the different researchers calculate them by different procedures. Therefore, in present work, experimental trials have been carried out per- forming migration tests following ASTM C1202-91 procedure, and modified by applying 12 Volts.
