Although the most of National Codes of Practices which deal with cracking recommends a limit for crack widths in order to control the risk of corrosion of reinforcement, the research to date has not sufficiently discussed the effect of cracks on carbonation of concrete. Therefore, this study has been carried out to improve the understanding of the effects of cracking on carbonation process. Mortar beams were used to investigate the effect of crack width on carbonation depth under an accelerating neuteralization test. Comparisons were made between the accelerated and exposure test results to evaluate the effect of acceleration on the carbonation depth. Also the influence of various constituents and curing time on carbonation depth was discussed.
