On uncertainties and inaccuracies in empirical chloride ingress modelling

Nilsson, Lars-Olof LU and Frederiksen, Jens M. (2011) In European Journal of Environmental and Civil Engineering 15(7). p.981-990
Abstract
This paper gives an overview of the current state-of-the-art of modelling chloride ingress and focuses on identified uncertainties and inaccuracies in the common way of applying the widely used empirical models. Examples are given in order to quantify the inaccuracies. It is also pointed out that inherent model uncertainties are likely to be of great importance due to lack of homogeneity in the data set laying behind the models. A major part of the parameter uncertainties is due to misunderstandings and lack of knowledge of decisive parts of the models, such as the time-dependency of the chloride diffusivity and the time-dependency of the surface chloride content.
