O estado da arte das técnicas de avaliação não destrutivas das estruturas de concreto

Abstract

Concrete is the most used material in the construction of structures, overcoming alternatives, also viable, such as wood and steel. However, despite the good durability of the material, it was noticed that this system was subject to significant and frequent damages caused by pathological manifestations. Because of this, it was necessary to look for methods capable of detecting such damages. In this sense, the present work seeks to present, based on a detailed research of the literature, the state of the art of evaluation techniques in concrete structures by means of non-destructive tests. It is worth saying that the knowledge about non- destructive testing techniques, besides enabling the monitoring of the quality and mechanical properties of the material - by means of tests that do not cause any damage or little damage to the structure - contributes to greater durability of buildings and reduces repair costs. However, it is necessary to know about the various test methods and their peculiarities, so that a broader investigation of the structure and the correct analysis of the results can be made.
