A probabilistic model was proposed to predict the life time of concrete subjected to frost damage. This model is based on the assumption that the frost damage is caused by microcrack .accumulation that is measured as the relation between the reduced relative dynamic modulus of elasticity and the freeze-thaw cycles. Three types of experiments were carried out to prove the applicability at the model. First is performed with mortar to study the influence of temperature. Second is carried out by RILEM-rriethod to study, the influence of moisture content. Third is done with mortar and concrete to study the influence of heterogeneity of the material structure. These experimental results were analyzed with this model. The reduction rate of relative dynamic modulus of elasticity was discussed as a function of the lowest temperature, the moisture content and material structures.
