Resumo: The elaboration of this article occurred after a research in which the comparative analysis of the influence of heating and cooling on concrete strength was studied. For this, tests were carried out in the laboratory, in addition to the concreting of the concrete in concrete mixer, where it was observed that the use of the trace of the material mentioned above, refers to the characteristic resistance of the compression of 25 Mpa. The research also made a comparative study between natural concrete and another that was exposed to high temperatures, in a gas furnace and soon after removed, subjected to a cooling with water, whose objective is to analyze the control and qualification of this concrete. As previously stated, the tests were all done in the laboratory in order to demonstrate the influence at high temperatures and in its instantaneous drop, where a trace of concrete was executed, that shaped 25 specimens of which twelve were made to prove if the trace contains the required characteristic resistance. As the tests were carried out after seven days, twenty-one days and twenty-eight days, it was observed that in all of them, the concrete did not gain resistance, but lost much of it, reaching a reduction of 66.74%. This draws attention to the importance of being aware of the material and its behavior, since a fire in structures such as those analyzed can lead to massive cases of death and material loss. Therefore, it is extremely important to make such an assessment, to avoid possible tragedies.

Para ello, se realizaron pruebas en laboratorio, además de la realización de la confección del hormigón en hormigón, donde se observó que la utilización del traza del material arriba mencionado, se refiere a la resistencia característica de la compresión de 25 Mpa. La investigación aún hizo un estudio comparativo entre el concreto natural y otro que fue expuesto a temperaturas elevadas, en un horno a gas y luego después de retirado, sometido a un enfriamiento con agua, cuyo objetivo es analizar el control y calificación de este concreto. En los últimos años, los ensayos se realizaron en laboratorio con la finalidad de demostrar la influencia en temperaturas elevadas y en secuencia, su caída instantánea, donde se ejecutó un trazado de concreto, que moldeó 25 cuerpos de prueba de los cuales doce fueron hechos para comprobar si el traza contiene la resistencia característica necesaria. Como las pruebas se efectuaron después de siete días, veintiún días y veintiocho días, se observó que en todos ellos, el hormigón no ganó resistencia, sino que perdió gran parte de la misma, llegando a una reducción del 66,74% . Esto llama la atención sobre la importancia de tener conocimiento del material y su comportamiento, ya que un incendio en estructuras como las analizadas, puede acarrear voluminosos casos de muertes y pérdidas materiales. Por lo tanto, es de extrema importancia hacer tal evaluación, para evitar posibles tragedias.A elaboração deste artigo ocorreu após uma pesquisa na qual foi estudada atentamente a análise comparativa da influência do aquecimento e resfriamento na resistência do concreto. Para isso, foram feitos testes em laboratório, além da realização da confecção do concreto em betoneira, onde observou-se que a utilização do traço do material acima mencionado, refere-se à resistência característica da compressão de 25 Mpa. A pesquisa ainda fez um estudo comparativo entre o concreto natural e outro que foi exposto a temperaturas elevadas, em um forno a gás e logo após retirado, submetido a um resfriamento com água, cujo objetivo é analisar o controle e qualificação desse concreto. Conforme dito anteriormente, os ensaios foram todos feitos em laboratório com a finalidade de demonstrar a influência em temperaturas elevadas e em sequência, sua queda instantânea, onde foi executado um traço de concreto, que moldaram 25 corpos de prova dos quais doze foram feitos para comprovar se o traço contém a resistência característica necessária. Como os testes foram efetuados após  sete dias, vinte e um dias e vinte e oito dias, foi observado que em todos eles, o concreto não ganhou resistência, e sim, perdeu grande parte da mesma, chegando a uma redução de 66,74%. Isso chama a atenção para a importância de se ter conhecimento do material e seu comportamento, visto que um incêndio em estruturas como as analisadas, pode acarretar volumosos casos de óbitos e perdas materiais. Sendo assim, é de extrema importância fazer tal avaliação, para evitar possíveis tragédias.Research, Society and Development2019-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/129110.33448/rsd-v8i10.1291Research, Society and Development; Vol. 8 No. 10; e068101291Research, Society and Development; Vol. 8 Núm. 10; e068101291Research, Society and Development; v. 8 n. 10; e0681012912525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/1291/1080Copyright (c) 2019 Pedro Emílio Amador Salomão, Rodrigo Silva Colares, Fabiano Mendes Pereira, Acly Ney Santiago de Oliveirainfo:eu-repo/semantics/openAccessSalomão, Pedro Emílio AmadorColares, Rodrigo SilvaPereira, Fabiano MendesOliveira, Acly Ney Santiago de2020-03-25T16:06:51Zoai:ojs.pkp.sfu.ca:article/1291Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:23.405729Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
