Correlación de las características físicas de los ladrillos mediante el método de velocidad de pulso ultrasónico

Abstract

Abstract:The use of non-destructive methods such as the ultrasonic pulse velocity method (UPV) can be of great help in the evaluation of masonry. However, due to the lack of research, the information is very limited and it reduce the use of this equipment in other materials. Therefore, the present study was carried out in order to establish correlations between the physical characteristics of the bricks and the UPV method in function of various temperatures. For this purpose, solid bricks were made with clays from four mines in the province of Loja; whose physical, chemical and mechanical properties were evaluated after the pieces had been fired, where measurements of velocity and modulus of elasticity were found through the use of ultrasonic Pundit equipment. Finally, it was determined that temperature affects both physical and mechanical parameters and that the correlation between the modulus of elasticity given by the equipment and the one calculated as a function of resistance, give values greater than 0.9. It verified that the results given by the Pundit equipment in the evaluation of bricks are reliability.
