Effect of Climatic Conditions on Modelling of Carbonation for RC Structures

Original language description

Carbonation-induced corrosion is the main degradation factor, which causes significant economic losses to the operators of an aging large, reinforced concrete (RC) structures such as cooling towers (CTs). Due to large variability of basic variables, the carbonation ingress process needs to be described by probabilistic model. In this study, the carbonation model is developed for practical applications in service life assessments of these structures exposed to environmental effects. Carbonation resistance of concrete as a main parameter affecting carbonation depth is difficult to obtain for existing structures. In most cases, it is thus only possible to describe carbonation ingress using carbonation depth data from in-situ surveys. Shape of the carbonation depth development curve with time is defined by the weather function which accounts for the effect of environmental exposure of the structure. The shape is essential for longterm predictions of carbonation ingress.
