Concrete is the structural material most used in the world and constitutes a basic part of engineering projects. However, concrete properties can vary considerably, depending on the nature and proportions of its constituents, the construction methods applied to create it, and the loading and environmental conditions to which it will be subjected over time. Therefore, the developments of control methods to determine the condition and ascertain the quality of concrete are critical. It is necessary to have tools to control and analyze the state of deterioration and security. Nondestructive Testing (NDT) methods become an attractive and viable strategy of inquiry. NDT can be described as a method to examine an object, material or system without causing damage or impairing its future usefulness. This work evaluates the usefulness and precision of Ultrasonic Tomography (UT) to develop adequate interpretation strategies to make sense of all the data obtained. The UT tests serve as tool to make an analysis of the concrete structures to allow the parameters for checking concrete conditions. In this study, the results of UT carried out on a bridge deck were analyzed. The results were tested using 3D tomography and indicate that this technique seems to be a useful way to analyze concrete structures.
