Types and Causes of Concrete Deterioration

Carbonation is generally a slow process. In high-quality con-crete, it has been estimated that carbonation will proceed at a rate up to 1.0 mm (0.04 in.) per year. The amount of carbonation is significantly increased in concrete with a high water-to-cement ratio, low cement content, short curing period, low strength, and highly permeable or ...
