Resumo: The civil construction sector is increasingly expanding due to demographic growth; consequently, greater demand for housing construction. However, there has been an alarming increase in the volume of generation of solid waste from construction and demolition (RCD). Therefore, this work has as main objective to use residues generated by physical losses in construction sites for partial and total replacement of the coarse aggregate of conventional concretes and to analyze its efficiency for structural purposes. For this purpose, experimental tests were carried out with the replacement of conventional coarse aggregate for aggregate consisting of construction and demolition waste in the contents of 50% and 100%. The results obtained were compared with that of conventional concrete. The reuse of RCD in the manufacture of conventional concretes may bring sustainable management to buildings, since their use can generate a reduction in the exploitation of natural resources, a decrease in the volume of waste deposited in the environment and a reduction in the CO2 emission, generated by the operations of transport of this material to its destination. Therefore, we sought to gather data / research to present how the feasibility of making recycled concrete from construction and demolition waste helps in the search for sustainable alternatives for the deposition of this waste. With the results obtained it was possible to observe that the recyclable concretes presented satisfactory values ​​for their use in civil construction if all technological control is carried out for their production and execution and can be used for structural purposes.

Sin embargo, ha habido un aumento alarmante en el volumen de generación de residuos sólidos de construcción y demolición (RCD). Por tanto, este trabajo tiene como principal objetivo utilizar los residuos generados por las pérdidas físicas en las obras para la sustitución parcial y total del agregado grueso de los hormigones convencionales y analizar su eficiencia para fines estructurales. Para ello, se realizaron ensayos experimentales con la sustitución de árido grueso convencional por árido constituido por residuos de construcción y demolición en contenidos de 50% y 100%. Los resultados obtenidos se compararon con los del hormigón convencional. La reutilización de RCD en la fabricación de hormigones convencionales puede aportar una gestión sostenible a los edificios, ya que su uso puede generar una reducción en la explotación de los recursos naturales, una disminución del volumen de residuos depositados en el medio ambiente y una reducción de la emisión de CO2, generado por las operaciones de transporte de este material hasta su destino final. Por lo tanto, buscamos recopilar datos / investigaciones para presentar cómo la viabilidad de hacer concreto reciclado a partir de residuos de construcción y demolición ayuda en la búsqueda de alternativas sostenibles para la deposición de estos residuos. Con los resultados obtenidos se pudo observar que los hormigones reciclables presentaron valores satisfactorios para su uso en construcción civil, siempre que se lleve a cabo todo el control tecnológico para su producción y ejecución, pudiendo ser utilizados con fines estructurales.O setor da construção civil está cada vez mais em expansão em decorrência do crescimento demográfico; consequentemente, maior demanda por construção de habitações. Porém, têm-se percebido um aumento alarmante no volume de geração dos resíduos sólidos oriundos de construção e demolição (RCD). Diante disso, esse trabalho tem como objetivo principal utilizar resíduos gerados por perdas físicas em canteiros de obras para substituição parcial e total do agregado graúdo dos concretos convencionais e analisar sua eficiência para fins estruturais. Para isso foram realizados ensaios experimentais com substituição de agregado graúdo convencional por agregado constituído de resíduos de construção e demolição nos teores de 50% e 100%. Os resultados obtidos foram comparados com o do concreto convencional. A reutilização de RCD na fabricação dos concretos convencionais poderá trazer um manejo sustentável nas construções, visto que sua utilização pode gerar redução na exploração de recursos naturais, diminuição no volume de resíduo depositado no meio ambiente e redução na emissão de CO2, gerada pelas operações de transporte desse material até a destinação final. Portanto, buscou-se reunir dados/pesquisas com o propósito de apresentar como a viabilidade da confecção de concreto reciclado oriundo de resíduo de construção e demolição auxilia na busca por alternativas sustentáveis para deposição desses resíduos.  Com os resultados obtidos foi possível observar que os concretos recicláveis apresentaram valores satisfatórios para seu uso na construção civil, desde que seja feito todo controle tecnológico para sua produção e execução, podendo ser utilizado para fins estruturais.Research, Society and Development2021-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1524610.33448/rsd-v10i5.15246Research, Society and Development; Vol. 10 No. 5; e46010515246Research, Society and Development; Vol. 10 Núm. 5; e46010515246Research, Society and Development; v. 10 n. 5; e460105152462525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15246/13594Copyright (c) 2021 Amanda Celestino Ponte; Mariana Medeiros Ximenes; Sedna Karla Uchôa Fernandeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Ponte, Amanda Celestino Ximenes, Mariana Medeiros Fernandes, Sedna Karla Uchôa2021-05-17T18:20:49Zoai:ojs.pkp.sfu.ca:article/15246Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:06.894568Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
