Resumen: | The development of non-destructive techniques has currently a high interest, such as those based on non-linear ultrasonic measurements. In this work it has been assessed the possible application of non-linear ultrasonic measurements for getting information related to the microstructure and properties of Portland cement mortars exposed to real and non-optimum environments. The pore structure was studied using mercury intrusion porosimetry and differential thermal analyses. Mechanical strengths and linear ultrasonic pulse velocity were determined. Regarding non-linear ultrasonic measurements, the results of parameters R and DIFA were analyzed. The tests were performed at 28 and 250 days. At later ages, a loss of microstructure refinement and a worsening of mechanical performance of the mortars were observed. The results of non-linear ultrasonic parameters R and DIFA overall agreed with those obtained for the microstructural and mechanical characterization performed. In particular, an adequate correlation between parameter DIFA and the pore size distributions was observed. |
