Resumo: The increasing waterproofing of urban spaces brings environmental problems and disasters, such as flooding, resulting from changes in rainwater that seep and pass, requiring greater capacity of micro and macro drainage systems. Permeable concrete (CPER), composed of Portland cement and coarse aggregate, gains space as a way to mitigate the effects of reducing permeable areas. In this context, the present work seeks to investigate the influence of the mixing sequence on the hydraulic and mechanical behavior of the roll-milled CPER, given the presence of gaps in the literature about the impact of these parameters on the material. For this, three sequences of mixtures were studied from the production of CPER plates of dimensions 40cmx40cmx10cm. The results of resistance to flexural alteration, porosity, tortuosity and permeability were analyzed. Statistically, no differences were found between the results, however, reduced the volume growth and pore area, changing as sequences when used in the production of concrete or inclined shaft mixer.

El hormigón permeable (CPER), compuesto por cemento Portland y árido grueso, gana espacio como forma de mitigar los efectos de la reducción de áreas permeables. En este contexto, el presente trabajo busca investigar la influencia de la secuencia de mezclado en el comportamiento hidráulico y mecánico del CPER producido con canto rodado, dada la existencia de vacíos en la literatura sobre el impacto de este parámetro en el material. Para ello, se estudiaron tres secuencias de mezclas a partir de la producción de placas CPER de dimensiones 40cmx40cmx10cm. Se analizaron los resultados de la resistencia a la tracción en flexión, porosidad, tortuosidad y permeabilidad. Estadísticamente, no hubo diferencias entre los resultados, sin embargo, sí hubo un aumento en el volumen y área de poro, cambiando las secuencias, al utilizar un mezclador de eje inclinado en la producción de hormigones.A crescente impermeabilização dos espaços urbanos traz consigo problemas e desastres ambientais como as inundações, em decorrência da alteração na dinâmica da água da chuva que infiltrava e passa a escoar, exigindo a maior capacidade dos sistemas de micro e macrodrenagem. O concreto permeável (CPER), composto por cimento Portland e agregado graúdo, ganha espaço como forma de mitigar os efeitos da redução das áreas permeáveis. Nesse contexto, o presente trabalho busca investigar a influência da sequência de mistura no comportamento hidráulico e mecânico do CPER produzido com seixo rolado, dada a existência de lacunas na literatura sobre o impacto desse parâmetro sobre material. Para tal, foram estudadas três sequências de misturas a partir da produção de placas de CPER de dimensões 40cmx40cmx10cm. Foram analisados os resultados de resistência à tração na flexão, porosidade, tortuosidade e permeabilidade. Estatisticamente, não foram verificadas diferenças entre os resultados, entretanto, observou-se o crescimento do volume e da área de poros, alterando-se as sequencias, quando utilizado na produção dos concretos um misturador de eixo inclinado.Research, Society and Development2021-04-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1420510.33448/rsd-v10i4.14205Research, Society and Development; Vol. 10 No. 4; e31110414205Research, Society and Development; Vol. 10 Núm. 4; e31110414205Research, Society and Development; v. 10 n. 4; e311104142052525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/14205/12721Copyright (c) 2021 Juliana Chaves Cordeiro; Denny Martins Freitas; Luciana de Nazaré Pinheiro Cordeiro; Arthur Aviz Palma e Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCordeiro, Juliana Chaves Freitas, Denny MartinsCordeiro, Luciana de Nazaré PinheiroSilva, Arthur Aviz Palma e 2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/14205Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:23.012115Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
