ABSTRACT
Concrete structures are a kind of goods which should be in good performance during its service life. The performance of concrete structures usually decays with time, due to various environmental actions. This chapter explores the model by K. Tuutti, and reviews the models related to the chloride transport in concrete. It introduces the major standards or codes related with chloride-induced durability of concrete structures. Chloride transport in concrete is often governed by different mechanisms, not only diffusion. Coupling the multi species with other transport mechanisms is necessary. The parameters for the chloride modeling are stochastic, and the probabilistic model might be a good option for predicting chloride transport. The prediction of service life of concrete in chloride-bearing environments needs extensive research, because the methods of calculation and the tests are far from satisfactory and have not been yet validated over the long term. V. Bastidas-Arteaga proposed a comprehensive probabilistic model f or chloride transport in unsaturated concrete.
