Resumo: | In recent decades, the growth of Portland cement production has intensified, given the growth of civil construction. However, the activities of the cement industries are extremely polluting and contribute a large share of CO2 emissions. Having adopted the global focus of increasing additions in Portland cements with a view to developing a more sustainable product, the objective of this work was to identify the potential for replacing part of the clinker in CPI and CPV ARI RS cements. Two types of limestone with a high content of calcium carbonate were used, one with a coarser grain size and the other with a finer grain size, producing different mortars in the laboratory. The influence of additions on chemical characteristics was verified through standardized tests (sulfur trioxide, insoluble residue, loss on fire, magnesium oxide) and physical tests on residue in the 75 micron sieve, hot expandability, paste consistency, onset and end of catch. The results obtained allowed us to verify that, with regard to the chemical aspect, there was a significant and expected increase in the loss to fire for the group of samples containing limestone filler. As for the physical aspects, it was found that there is a strong relationship between the higher compressive strengths and the physical effects provided by the presence of ultrafine particles. The additions resulted in cements with high compressive strengths for all ages, considering a 50% reduction in clinker in the composition of CPI and CPV ARI RS cements. |

Sin embargo, las actividades de las industrias cementeras son extremadamente contaminantes y contribuyen en gran medida a las emisiones de CO2. Habiendo adoptado el enfoque global de incrementar las adiciones en cementos Portland con miras a desarrollar un producto más sustentable, el objetivo de este trabajo fue identificar el potencial para reemplazar parte del clinker en los cementos CPI y CPV ARI RS. Se utilizaron dos tipos de calizas con alto contenido en carbonato cálcico, una con granulometría más gruesa y otra con granulometría más fina, produciendo diferentes morteros en laboratorio. La influencia de las adiciones en las características químicas se verificó mediante pruebas estandarizadas (trióxido de azufre, residuo insoluble, pérdida al fuego, óxido de magnesio) y pruebas físicas sobre el residuo en el tamiz de 75 micrones, capacidad de expansión en caliente, consistencia de la pasta, inicio y fin de la captura. Los resultados obtenidos permitieron constatar que, en lo que respecta al aspecto químico, hubo un aumento significativo y esperado de las pérdidas por incendio para el grupo de muestras que contenían filler calizo. En cuanto a los aspectos físicos, se encontró que existe una fuerte relación entre las mayores resistencias a la compresión y los efectos físicos proporcionados por la presencia de partículas ultrafinas, especialmente para el grupo CFB. Las adiciones dieron como resultado cementos con altas resistencias a la compresión para todas las edades, considerando una reducción del 50% del clinker en la composición de los cementos CPI y CPV ARI RS.Nas últimas décadas, o crescimento da produção de cimento Portland tem se intensificado, dado o crescimento da construção civil. No entanto, as atividades das indústrias cimenteiras são extremamente poluentes e contribuem com uma grande parcela nas emissões de CO2. Tendo o foco mundialmente adotado de aumento das adições nos cimentos Portland com a visão de desenvolvimento de um produto mais sustentável, o objetivo deste trabalho foi identificar o potencial de substituição de parte do clínquer nos cimentos CPI e CPV ARI RS. Foram utilizados dois tipos de calcário com elevado teor de carbonato de cálcio, um com granulometria mais grossa e o outro com granulometria mais fina produzindo, em laboratório, diferentes argamassas. Verificou-se a influência das adições nas características químicas através dos ensaios normatizados (trióxido de enxofre, resíduo insolúvel, perda ao fogo, óxido de magnésio) e nos ensaios físicos resíduo na peneira 75 microns, expansibilidade a quente, consistência da pasta, início e fim de pega. Os resultados obtidos permitiram verificar que, no que diz respeito ao aspecto químico houve um aumento significativo e esperado na perda ao fogo para o grupo de amostras contendo fíler de calcário. Já para os aspectos físicos, constatou-se que existe uma forte relação entre as maiores resistências à compressão e os efeitos físicos proporcionados pela presença de partículas ultrafinas. Das adições, resultaram cimentos com elevadas resistências à compressão para todas as idades tendo em vista a redução de 50% de clínquer na composição dos cimentos CPI e CPV ARI RS.Research, Society and Development2021-10-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2127210.33448/rsd-v10i13.21272Research, Society and Development; Vol. 10 No. 13; e309101321272Research, Society and Development; Vol. 10 Núm. 13; e309101321272Research, Society and Development; v. 10 n. 13; e3091013212722525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/21272/18948Copyright (c) 2021 Gilson Vicente da Silva; Simone Pereira Taguchi Borges; Audrei Giménez Barañanohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Gilson Vicente daBorges, Simone Pereira TaguchiBarañano, Audrei Giménez2021-11-21T18:26:28Zoai:ojs.pkp.sfu.ca:article/21272Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:43.570673Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
