“…This method is extremely useful in the study of assessing a large quantity of material and of finding location with excessive or variable humidity [35]. The active thermography method can be used to visualize invisible discontinuities, e.g., cracks and scratches [36], [37]. is determined using penetration [8] and magnetic methods [40].…”

Construction and demolition (C&D) waste management should be accordance with the waste management hierarchy. In practice, C&D waste are often downcycling. It is the result of many factors, including lack of awareness about the value inherent in waste. The paper presents analysis of the adaptability of non-destructive testing (NDT) methods for technical assessment of waste properties. As part of the work, non-destructive testing methods were described and classified in accordance with material and the features they enable testing. The publication presents examples of the use of NDT in the recovery of building materials during construction projects, in the field of influence of technical information of waste on the way it is managed. Finally, a scheme of waste management process during the renovation of an object with the application of NDT methods was presented.

“…For active thermography (AT), a heating or cooling flow is generated and propagated into the test object, thermal responses according to the Stefan-Boltzmann law are then detected and recorded to reveal internal structures. Recent advances in signal processing techniques and equipment developments have made the AT method more practical and effective than the conventional PT approach [105,106].…”

Composite materials/structures are advancing in product efficiency, cost-effectiveness and the development of superior specific properties. There are increasing demands in their applications to load-carrying structures in aerospace, wind turbines, transportation, and medical equipment, etc. Thus robust and reliable non-destructive testing (NDT) of composites is essential to reduce safety concerns and maintenance costs. There have been various NDT methods built upon different principles for quality assurance during the whole lifecycle of a composite product. This paper reviews the most established NDT techniques for detection and evaluation of defects/damage evolution in composites. These include acoustic emission, ultrasonic testing, infrared thermography, terahertz testing, shearography, digital image correlation, as well as X-ray and neutron imaging. For each NDT technique, we cover a brief historical background, principles, standard practices, equipment and facilities used for composite research. We also compare and discuss their benefits and limitations, and further summarise their capabilities and applications to composite structures. Each NDT technique has its own potential and rarely achieves a full-scale diagnosis of structural integrity. Future development of NDT techniques for composites will be directed towards intelligent and automated inspection systems with high accuracy and efficient data processing capabilities.

“…Conforme sumário realizado por Doshvarpassand [7], em uma revisão de artigos publicados de 2013 a 2019 sobre aplicações termográficas mais comuns nas indústrias, que dizem respeito a detecção de vazamento e infiltração, foram apenas 0,5% dentre todos os segmentos de indústrias pesquisadas, e menos de 2% dentre aplicações em estruturas e materiais metálicos. Muito pouco na literatura é mencionado sobre aplicação de mecanismos de resfriamento em vez de aquecimento, considerando que os mecanismos de transferência de calor para aquecimento e resfriamento são similares.…”

Resumo: Um problema grave que ocorre entre caldeira e precipitador termostático é a entrada falsa de ar nos dutos de gases. A proposta deste trabalho foi apresentar e validar uma metodologia de inspeção externa destes dutos, durante operação da caldeira, por câmera termográfica embarcada em drone, para direcionar os devidos reparos durante o shutdown. Pela análise das imagens termográficas captadas, foram identificados 132 não conformidades nos dutos inspecionados, dos quais 20 foram referentes a pontos frios, como potenciais locais de entrada falsa de ar para os gases. Com a utilização da metodologia proposta neste trabalho, ficou bastante evidente os ganhos substanciais quanto a qualidade da informação produzida, reduções de custo e tempo operacional da inspeção e garantia da saúde e vida dos envolvidos.
