Abstract

The Corrosion of reinforcement in concrete has been identified as a major cause of deterioration in reinforced concrete (RC) structures. Carbonation is the one of the factor which affect the durability of concrete and accelerates the corrosion in RC structures. Results from previous studies shows that co2 concentration in the atmosphere was 390ppm in the year 2010. That will increase at 414ppm in the year 2020, the increasing co2 concentration in atmosphere increases carbonation effect in concrete and it leads to reinforcement corrosion in RC structures. Hence adoption of suitable protective measures are essential for exposed RC structures against carbonation induced corrosion. In this study we numerically evaluate the concrete carbonation with different climatic condition using the mathematical software MATLAB and compare these results with the existing models. The results conclude that the Yoon model is relatively nearer to the existing building modelling, Numerical model created in the MATLAB is verified with experimental investigation.
