Summary: | The infrared thermography can show, in a non-destructive way, pathological manifestations before them becoming visible and more harmful, due to the existence of inconsistencies in the thermal patterns of the elements of the structure that exhibit pathological manifestations. The thermal evaluation with basis on thermography is the perception of the superficial temperature of a body through the heat transfer mechanism), once every body with temperature above absolute zero emits thermal radiation. This study aims to qualitatively analyze the use of digital thermal experiment in order to detect the occurrence of corrosion in posts made of reinforced concrete located on Olinda's beachfront (PE). The experiments were performed on 10 posts between 14 and 15 o'clock, with verification on the front side (with direct activity of salty spray), and on the back side. The equipment used was a thermal camera, FLIR E-60. The surroundings of the experiments have environmental aggressiveness level IV (very intense), with elevated risk of deterioration. In the experiment analysis, it is possible to verify that the corrosion products conduct more heat, presenting a higher temperature than on the concrete, therefore, the search for the occurrence of corrosion is related to the detection of temperatures higher than the ones verified as a tendency in concrete. The experiments showed that an elevated temperature in concrete cracks may be an indication of the occurrence of corrosion on reinforcements, as well as, through the analysis of thermograms were identified indications of corrosion on the analyzed structure. |

La evaluación térmica basada en la termografía es una percepción de la temperatura superficial de un cuerpo mediante el mecanismo de transferencia térmica, ya que todo cuerpo con una temperatura superior al cero absoluto emite radiación térmica. El objetivo de este estudio es analizar cualitativamente el uso del ensayo térmico digital para detectar corrosión en postes de hormigón armado situados en la periferia de la ciudad de Olinda-PE. Los ensayos se realizaron en 10 postes entre las 2 y las 3 de la tarde, con verificación tanto en la cara frontal (con acción directa de las salpicaduras de niebla salina) como en la cara opuesta. El dispositivo utilizado fue una cámara termográfica, modelo FLIR E-60. El ambiente de los ensayos presenta clase IV de agresividad ambiental (muy fuerte), con riesgo de deterioro elevado. En el análisis de los ensayos puede verificarse que los productos de la corrosión conducen más calor, con una temperatura más elevada que el hormigón; por lo tanto, buscar instancias de corrosión se vincula a la detección de temperaturas más elevadas que las verificadas como tendencia en el hormigón. Los ensayos demuestran que una temperatura elevada en grietas del hormigón puede indicar corrosión en las armaduras, al igual que se identificaron indicios de corrosión en las estructuras analizadas a través del análisis de los termogramas.A termografia infravermelha pode mostrar, de forma não destrutiva, manifestações patológicas antes de tornarem-se visíveis e mais danosas, devido à existência de incoerências nos padrões de temperatura dos elementos da estrutura que apresentem as manifestações patológicas. A avaliação térmica com base na termografia é a percepção da temperatura superficial de um corpo pelo mecanismo de transferência de calor, pois todo corpo com temperatura acima do zero absoluto emite radiação térmica. Esse estudo objetiva analisar qualitativamente a utilização do ensaio térmico digital para detectar a ocorrência de corrosão em postes de concreto armado situados na orla da cidade de Olinda-PE. Os ensaios foram realizados em 10 postes no período das 14 às 15 horas, com verificação no face frontal (com ação direta dos respingos de névoa salina) e também na face oposta. O equipamento utilizado foi uma câmera termográfica, FLIR E-60. O ambiente dos ensaios tem classe de agressividade ambiental IV (muito forte), com risco de deterioração elevada. Na análise dos ensaios é possível verificar que os produtos da corrosão conduzem mais calor, apresentando uma temperatura mais elevada que o concreto, portanto, a procura pela ocorrência de corrosão está ligada à detecção de temperaturas mais elevadas do que as verificadas como tendência no concreto. Os ensaios mostraram que uma temperatura elevada em trincas no concreto podem ser uma indicação da ocorrência de corrosão de armaduras, assim como, através da análise dos termogramas, foram identificados indícios de corrosão nas estruturas analisadas.Research, Society and Development2022-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2806510.33448/rsd-v11i5.28065Research, Society and Development; Vol. 11 No. 5; e27911528065Research, Society and Development; Vol. 11 Núm. 5; e27911528065Research, Society and Development; v. 11 n. 5; e279115280652525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/28065/24558Copyright (c) 2022 Lucas Amorim Amaral Menezes; Yêda Vieira Póvoas; Diego José Araújo Viégashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMenezes, Lucas Amorim AmaralPóvoas, Yêda VieiraViégas, Diego José Araújo2022-04-17T18:18:56Zoai:ojs.pkp.sfu.ca:article/28065Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:45:36.077782Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
