Ultrasonic testing of concrete structures
Despite the limitations imposed by the material character, ultrasonic tests have been applied successfully to concrete structures. The ultrasonic pulse velocity method is an effective and practical means of investigating the uniformity of concrete and, in conjunction with imaging procedures, provides an effective method to locate interior discontinuities within concrete. The method can also be applied to estimate the in place concrete strength; however, a large number of variables affect the relations between the strength parameters of concrete and its pulse velocity. The use of ultrasonic pulse velocity to estimate the compressive or flexural strengths of concrete is not recommended unless previous correlation testing has been performed. The ultrasonic interfacial wave reflection method is effective in monitoring the stiffening and hardening process of early age concrete.
