The cracks in the concrete structure accelerate the carbonization of concrete at the cracks, which affects the durability of the concrete structure. The carbonation characteristics of the concrete at the crack are analyzed. Based on the discussion of the factors affecting the concrete carbonation at the cracks, the empirical calculation formula for the carbonation depth of the concrete at the cracks is given. Based on the measured data, a stochastic process model for the concrete carbonation depth at the cracks is established. This method provides a reliable method for predicting the depth of carbonation in cracks of concrete structures mainly subjected to static loading.
