Resumo: Precast in civil construction provides high technological control and reduction of waste, materials, and time in the construction process. Considering the residues generated in the processes in the production of artifacts, this study aims to investigate the use of precast residues with the addition of rare earth photoluminescent substances in the production of concrete artifacts to illuminate paths. The experiment was carried out in two stages: The first stage was the evaluation of the granulometry after the crushing process, production of traces, and mechanical resistance test. In the second stage, using the best trace, there was the application and test with a photoluminescent substance. The first stage results show the predominance of medium and fine particulates, with a greater amount in sieves with openings of 1.18 mm and 4.75 mm. Regarding the physical properties of concrete, mixture 1 showed a better specific mass, better slump performance, and mechanical strength in cured concrete. Regarding the use of photoluminescent substances in the emission of photons, after exposure to solar radiation, the experiments did not show the desired results.

Considerando los residuos generados en los procesos en la producción de artefactos, el objetivo de este estudio es investigar el uso de residuos prefabricados con la adición de sustancias fotoluminiscentes de tierras raras en la producción de artefactos de hormigón para iluminar caminos. El experimento se realizó en dos etapas: La primera etapa fue la evaluación de la granulometría posterior al proceso de trituración, producción de trazas y prueba de resistencia mecánica. En la segunda etapa, utilizando la mejor traza, se realizó la aplicación y prueba con sustancia fotoluminiscente. Los resultados de la primera etapa muestran el predominio de partículas medianas y finas, con mayor cantidad en tamices con aberturas de 1,18 mm y 4,75 mm. En cuanto a las propiedades físicas del concreto, la mezcla 1 mostró mejor masa específica, mejor comportamiento de revenimiento y resistencia mecánica en el concreto curado. En cuanto al uso de sustancias fotoluminiscentes en la emisión de fotones, después de la exposición a la radiación solar, los experimentos no arrojaron los resultados deseados.O pré-moldado na construção civil proporciona alto controle tecnológico e redução de desperdícios, materiais e tempo no processo construtivo.

Quanto às propriedades físicas do concreto, a mistura 1 apresentou melhor massa específica, melhor desempenho no abatimento e resistência mecânica no concreto curado. Em relação ao uso das substâncias fotoluminescentes na emissão de fótons, após exposição à radiação solar, os experimentos não apresentaram os resultados desejados.Research, Society and Development2022-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3314510.33448/rsd-v11i10.33145Research, Society and Development; Vol. 11 No. 10; e490111033145Research, Society and Development; Vol. 11 Núm. 10; e490111033145Research, Society and Development; v. 11 n. 10; e4901110331452525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/33145/28026Copyright (c) 2022 Monalisa Both; Paulo Reis Junior; Jacir Favretto; Mari Aurora Favero Reishttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBoth, MonalisaReis Junior, PauloFavretto, JacirReis, Mari Aurora Favero2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/33145Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:53.420565Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
