Abstract

The frost durability of concrete is considered from structural engineering points of view. Specific failure process is analyzed and a damage model is established, which can describe the deterioration of concrete during the whole freeze-thawing process. The model is verified by test data. The parameters of model can explain the effect of pore structures or water to binder ratio on frost durability of concrete.
