Abstract

This paper examines the process of carbonation in concrete as while as factors that influence carbonation progression in concrete. Quantification of carbonation process in an inland environment and basis for the derivation of the carbonation progression rate in concrete were also reviewed. The paper then x-rayed extensively existing carbonation prediction models and finally it proposed an approach for the development of carbonation prediction model for reinforced concrete structures located in an inland environment.
