A Review on Carbonation of Concrete and Its Prediction Modelling

The phenomenon of concrete carbonation is a well-researched field. With ever rising concern of pollution in environment, need for understanding this phenomenon has increased many folds. Although, there is plenty of experimental data is anavailable, useful and quantifiable generalisation of influences of different factors affecting parameters is a difficult task as there is innumerable variability in experimental conditions and ingredients of the concretes tested and the specimens taken for conduction of tests. Several studies have employed numerical and statistical modelling techniques to predict the depth of carbonation as a function of theage of concrete, compressive strength of concrete and other parameters affecting carbonation of concrete. This paper discusses several issues of uncertainty in prediction and evaluation of carbonation propagation.
