Resumo: | The replacement of conventional materials used in hot asphalt mixtures with others of good technique and lower cost and environmental impact has motivated research in this area of knowledge in recent decades. The researches should be expanded in the scope of engineering, given that it contributes considerably to the transformation of spaces and raw material. In this context, thermoelectric ashes, which are residues from the production of electric energy, appear as an alternative to replace the stone powder input which contributes negatively to the environment considering that it comes from the blasting of rocks. This work aims to compare the cost of producing traditional asphalt concrete (reference) to asphalt compositions containing 5,15% of alternative material characterized by stone dust. There was a saving of R$ 0.21 per ton of AC machining, consisting of thermoelectric ash as a partial substitute (5.15%) for stone powder, which represents significant savings in a practical context. |

Las investigaciones deben ampliarse en el ámbito de la ingeniería, dado que contribuye considerablemente a la transformación de espacios y materia prima. En este contexto, las cenizas termoeléctricas, que son residuos de la producción de energía eléctrica, aparecen como una alternativa para reemplazar el aporte de polvo de piedra que contribuye negativamente al medio ambiente considerando que proviene de la voladura de rocas. Este trabajo tiene como objetivo comparar el costo de producción de hormigón asfáltico tradicional (referencia) con composiciones asfálticas que contienen un 5,15% de material alternativo caracterizado por polvo de piedra. Hubo un ahorro de R $ 0,21 por tonelada de mecanizado de CA, consistente en ceniza termoeléctrica como sustituto parcial (5,15%) del polvo de piedra, lo que representa un ahorro significativo en un contexto práctico.A substituição de materiais convencionais utilizados em misturas asfálticas a quente por outros de boa técnica e menor custo e impacto ambiental tem motivado pesquisas nesta área do conhecimento nas últimas décadas. As pesquisas devem ser ampliadas no âmbito da engenharia, visto que ela contribui consideravelmente para a transformação dos espaços e da matéria-prima. Nesse contexto, as cinzas termelétricas, que são resíduos da produção de energia elétrica, surgem como uma alternativa para substituir o pó de pedra que contribui negativamente para o meio ambiente por ser proveniente do desmonte de rochas. Este trabalho tem como objetivo comparar o custo de produção de concreto asfáltico tradicional (referência) com composições asfálticas contendo 5,15% de material alternativo caracterizado por pó de pedra. Houve uma economia de R$ 0,21 por tonelada de usinagem AC, composta pela cinza termelétrica em substituição parcial (5,15%) do pó de pedra, o que representa uma economia significativa na prática.Research, Society and Development2021-08-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1856410.33448/rsd-v10i10.18564Research, Society and Development; Vol. 10 No. 10; e28101018564Research, Society and Development; Vol. 10 Núm. 10; e28101018564Research, Society and Development; v. 10 n. 10; e281010185642525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/18564/16550Copyright (c) 2021 Igor Nonato Almeida Pereira; Newton Paulo de Souza Falcão; Consuelo Alves da Frotahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPereira, Igor Nonato Almeida Falcão, Newton Paulo de Souza Frota, Consuelo Alves da 2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/18564Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:40.708020Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
