Abstract

The ultrasonic waves velocity method is a technique that is related to the propagation of the waves through the material that is being evaluated. It is considered a nondestructive test and can also be utilized to evaluate the quality of the concrete. Through this method it is possible, for example, to obtain the thickness of concrete slabs and to estimate the strength of concrete. This research aims to present results obtained though the application of ultrasonic waves propagation method in the detection of the first cracks in strengthened concrete beams (solicitadas í  flexão simples). The method is also used to evaluate the strength of concrete during the first days. The results show that the method can be used to estimate the strength of concrete and, if correctly used, can be useful in strenghtened concrete beams tests to detect first cracks.
