Abstract The renovation of existing buildings and infrastructures is becoming in the last years increasingly important. This results in an increasingly greater need to understand the real condition of building components and to objectively measure their level of damage with both qualitative and quantitative indicators. There are many known methods in the field of structural health monitoring and damage control. Among them, non-destructive testing (NDT) methods assume particular importance as they enable the evaluation of structural integrity without compromising functionality. This article explores the potential of non-destructive testing using computed tomography (CT) in the context of damage analysis for concrete structures. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction Among the various known methods in the field of structural health monitoring and damage control, non-destructive testing (NDT) is one of the very promising but also challenging ones. One NDT technique that is characterized by providing visual information of the interior of the material at laboratory scale and in practice is computed tomography (CT). This technique can be particularly useful in concrete, a material for which inspection and monitoring techniques are commonly restricted to external surface analysis. The possibility of using CT imaging technology introduces a differentiating factor in this regard, as it provides valuable insight into concrete’s internal structure.
