Abstract:

This article proposes a review of the non-destructive tests (NDT) of concrete evaluation. NDT’s are widely explored and studied, as they have great potential in the inspection process for concrete elements. Several factors favour the use of non-destructive techniques in this analysis, being the subject of several studies today. Due to the advancement of technology within civil construction, there was a great acceptance of these techniques in the process of assessing strength, uniformity, durability, and other properties of concrete. The non-use of NDT’s is, in most cases, due to the lack of full knowledge of the techniques that could be applied. In this way, the article proposes to approach this theme, describing and exposing some examples where the application of the NDT’s was successful in concrete structures.

Keywords: NDT, Concrete, Civil, Evaluation.
