Abstract: An extensive carbonation survey was conducted of a 19-year-old commercial building that was situated in a tropical environment. A significant reduction in carbonation was found for those structural components that were plastered (sand-cement render) compared to those with no surface finishing. There was no carbonation of the concrete when the plaster (render) thickness exceeded 30 mm. The carbonation data on non-plastered structural components showed that the depth of carbonation decreased with increasing core strength. The measured carbonation rate constant (K= 5.05 mm yr-0.5) is consistent with previous measurements in a similar climate but is higher than reported for structures in temperate climates (K = 1 to 3 mm yr-0.5).
