The durability of mortar structures is affected by chemical and mechanical factors, such as abrasion, temperature variation..., the Degradation of mortar structures located under flowing water in their structure or high humidity atmospheres. In this study we presented a method for ultrasonic non-destructive characterization in mortar to follow the evolution of the signals back scattered by mortar structures for different size of sand, Samples were manufactured using same water/cement ration (w/c) 0.65, and cement/sand ration (c/s) 0.5. The processing of the ultrasound wave has been chosen to follow the hardening of mortar and to understand the mechanisms driving to the degradation of mortar in relation with microstructure.
