Carbonization predicting on existing concrete structures is a key index for predicting the future state
about concrete structures. Based on the classics deduction course about one direction carbonization, a calculation formula of the maximum carbonization depth at the corner is obtained. In the light of analyzing the factors influencing concrete carbonization, a experiential calculation formula is recommended, and a stochastic process model of general edge carbonization depth is set up according to the measurement data in situ. A stochsatic process of the deepest carbonization in the comer is formulated with the method of analogy. A reliable way is provided for predicting carbonization depth.
