Avaliação da utilização e viabilidade da termografia infravermelha em inspeções de revestimentos e estruturas na construção civil

Abstract

Infrared thermography has shown great potential in civil construction. The use of equipment in inspections can help in the identification and diagnosis of pathological manifestations, reducing time, cost and risk in activities. Although the technique has potential in civil construction, it is still little known and used by professionals in the field. The present work aims to develop na analysis on the use of infrared thermography in inspections of coatings and structures in civil construction, seeking to demonstrate its application in building and industrial inspections, the limitations and difficulties of the equipment, its importance in maintenance and non-destructivetests, and issues related to equipment cost. To develop the proposed objective, a thermographic mapping was carried out on the chimney of two boilers in an industrial plant. The results obtained prove that the technique has precision and potential to identify hidden anomalies, allowing to measure the extent of the problem and to identify the areas that require more attention. With the study carried out it was also observed that the shortage of professionals who use the technique, may be linked to the high investment, knowledge and practice that infrared thermography requires.
