This chapter treats concrete damage caused by freeze–thaw actions in natural environments. Typical structural cases are first introduced to illustrate the effect of frost action on the deterioration of structural performance. The mechanisms of freezing in concrete pores are explained on the basis of pore crystallization, together with a comprehensive analysis of the factors influencing frost damage. From the available knowledge, two conceptual models are given for the critical saturation and mean pore stress from freezing. Some simulations are performed for typical engineering applications. Finally, the damage pattern and the structural consequences of frost action are discussed, and the design basis for reinforced concrete elements against frost action is elaborated.
