Abstract:
The use of accelerated laboratory testing and Flick's second law for chloride penetration may lead to values of the diffusion coefficient one to two orders of magnitude too high compared to the same concrete's real-life behavior. Several authors have observed this and questioned the validity of using Flick's second law in this context. This calls for a paradigm shift in the conception of the chloride penetration into concrete.
