Modeling the influence of chemical reactions on the mechanisms of ionic transport in porous materials - An overview

This paper attempts to critically review various approaches developed to mo del the effects of chemical reactions on the mechanisms of ionic transport in porous media. A comprehensive overview of the various types of chemical; reactions that can occur in reactive porous solids is first presented. Meth ods to model each of these chemical reactions are then described and analyz ed. The ability of each of the proposed algorithms to predict the behavior of hydrated cement systems is discussed. The implementation of these algori thms in an ionic transport numerical model is also discussed. (C) 2001 Else vier Science Ltd.-All rights reserved.
