Internal Deterioration of Mortars in Freeze-Thawing: Non-Destructive Evaluation by Means of Electrical Impedance

In this work, different mortars with different degrees of damage brought about by the action of the freeze-thawing cycles are evaluated. Analysis of its state is carried out by different usual evaluation methods. Results obtained through these methods are compared with the electrical impedance spectroscopy. Moreover, this non-destructive technique is employed to evaluate the state of mortars and the amount of internal damage.
