Resumo: | The use of byproducts and industrial waste as pozzolanic, is an alternative to achieve the sustainability, economy and durability in concrete structures. This survey has as its purpose to analyze the effect on mechanical, elastic and deformation properties on concrete with a high level of granulated slag from blast furnace and fly ash in place of Portland bulk cement. The use of high levels of mineral additions has the purpose of increasing the durability and reducing the consumption of cement, the use of hydrated lime aims to activating these adittions, restore part of the calcium hydroxide consumed by the pozzolanic reactions, increasing the initial and final strength to the mixtures. This way, three mixtures of concrete have been studied: one of them without mineral additions, only using Portland cement (CP V-ARI), taken as a control, with relations a/c 0.40, 0.60 and 0.83, and two mixtures with mineral additions in place of cement in equal mass, with 70% of slag and 20% of fly ash, being one of them with addition of 20% of hydrated lime on the mass of binders in addition to the cement, both to the relations a/mc 0.30/0.33, 0.40 and 0.49, which have been renamed as R, EV and EVC. Tests were held to resistance to axial compression in bodies of evidence (10x20cm) the ages of 07 28, 91 and 300 days, whose results range from 18.2 MPa and 81 MPa, tests of resistance to traction by diametral compression and module of elasticity at 28, 91 and 300 days, as well as tests of total shrinkage on prismatic bodies of evidence (10x10x30 cm) at 28, 91, 180 and 300 days. The results of mechanical, elastic and strain resistance have been also correlated with some intervening and independent variables, as well as some existing regulatory requirements. The results have been analyzed to each trace individually, in relation to the control traces, in relation to the evolution of the resistance, effectiveness of the use of the hydrated lime and in equal relationship a/mc 0.4. In the analysis of the equal relationship a/mc 0.400, in the case of reference concrete, in the initial age, the resistance to the axial compression of the concrete EV was, in media, 72% of the one presented by it, being the resistance to the EVC 55%, and in the final age, 65% and 50% respectively. In the case of the traction by diametral compression, to 28 days the concrete EV presented 76% of the resistance of the reference, and the concrete EVC 58%. This relation to 300 days was 80% and 61% respectively. To the elasticity module, to 28 days, the concrete EV presented 82% and the EVC 70% of the result obtained by the reference mixture, maintaining this proportion until the final age (300 days). In the analysis of the total retraction, the concrete EV presented an inferior retraction 10% inferior to the reference trace, while the concrete EVC to 300 days presents a good retraction 16% superior to it. The observation through the conjuncture of the results found shows a satisfactory relation among the different traces studied, making feasible the use of high levels of mineral additions in substitution to the large portion of cement in bulk. |

Esta pesquisa possui o objetivo de analisar os efeitos nas propriedades mecânicas, elásticas e de deformação em concretos com elevados teores de escória granulada de alto-forno e cinza volante em substituição ao cimento Portland em massa. O uso de altos teores de adições minerais tem por fim o aumento da durabilidade e redução do consumo de cimento, tendo o uso de cal hidratada a finalidade de ativar estas adições, repor parte do hidróxido de cálcio consumido pelas reações pozolânicas, aumentando as resistências iniciais e finais das misturas. Desta forma, estudaram-se três misturas de concreto: uma sem adições minerais, somente com cimento Portland (CP V-ARI), tomada como referência, com relações a/c 0.40, 0.60 e 0.83, e duas misturas com adições minerais em substituição ao cimento em igual massa, com 70% de escória e 20% de cinza volante, sendo uma delas com adição de 20% de cal hidratada em relação á massa de aglomerantes em adição ao cimento, ambas para relações a/mc 0.30/0.33, 0.40 e 0.49, as quais foram renomeadas como R, EV e EVC. Foram realizados ensaios de resistência a compressão axial em corpos de prova (10x20 cm) nas idades de 07, 28, 91 e 300 dias, cujos resultados variaram entre 18.2 MPa e 81 MPa, ensaios de resistência a tração por compressão diametral e módulo de elasticidade aos 28, 91 e 300 dias, assim como ensaios de retração total em corpos de prova prismáticos (10x10x30 cm) aos 28, 91, 180 e 300 dias. Também se correlacionou os resultados das resistências mecânicas, elásticas e de deformação com algumas variáveis intervenientes e independentes apresentadas, assim como com algumas prescrições normativas existentes. Os resultados foram analisados para cada traço individualmente, em relação aos traços referências, em relação à evolução da resistência, eficiência do uso da cal hidratada e em igualdade de relação a/mc 0.4. Na análise de igualdade de relação a/mc 0.400, em relação ao concreto referência, na idade inicial, a resistência a compressão axial do concreto EV foi, em média, 72% da apresentada por este, sendo a resistência do EVC 55%, e na idade final, 65% e 50%, respectivamente. Em relação à resistência a tração por compressão diametral, aos 28 dias o concreto EV apresentava 76% da resistência do referência, e o concreto EVC 58%. Esta relação, aos 300 dias foi de 80% e 61% respectivamente. Para o módulo de elasticidade, aos 28 dias, o concreto EV apresentou 82% e o EVC 70% do resultado obtido pela mistura referência, mantendo-se esta proporção até a idade final (300 dias). Na análise da retração total, o concreto EV apresentou uma retração 10% inferior ao traço referência, enquanto o concreto EVC aos 300 dias apresentou uma retração 16% superior ao mesmo. A observação através da conjuntura dos resultados obtidos demonstra uma satisfatória relação entre os diferentes traços estudados, viabilizando o uso de elevados teores de adições minerais em substituição a grande parcela de cimento em massa.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia CivilUFSMBREngenharia CivilConcretoCinza-volanteEscóriaCal hidratadaResistênciaMódulo de elasticidadeRetraçãoConcreteFlay ashSlagLime hydratedStrengthModulus of elasticityTotal shrinkageCNPQ::ENGENHARIAS::ENGENHARIA CIVILEfeitos nas propriedades mecânicas, elásticas e de deformação em concretos com altos teores de escória e cinza volanteEffects on mechanical, elastic and deformation properties on concrete with high levels of slag and fly ashinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisIsaia, Geraldo Cechellahttp://lattes.cnpq.br/8260652949733370Gastaldini, Antonio Luiz Guerrahttp://lattes.cnpq.br/9293085240832049Silva Filho, Luiz Carlos Pinto dahttp://lattes.cnpq.br/3933111188654098http://lattes.cnpq.br/5928401473224948Beck, Sílvio Maurício3001000000034003003003003005d5ff349-6e1b-45f0-a3fc-dfb31b446decd1d8cac4-3692-4c2a-9f3c-22fb7a2581ae6a0102db-7d1b-4dd8-8f1d-555760a238eb6a21fbec-d070-46b1-8919-2562ec8afe5cinfo:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALBECK, SILVIO MAURICIO.pdfapplication/pdf2255341http://repositorio.ufsm.br/bitstream/1/7721/1/BECK%2c%20SILVIO%20MAURICIO.pdf3dc7b40f429da32de5dbf67d5741322fMD51TEXTBECK, SILVIO MAURICIO.pdf.txtBECK, SILVIO MAURICIO.pdf.txtExtracted texttext/plain264249http://repositorio.ufsm.br/bitstream/1/7721/2/BECK%2c%20SILVIO%20MAURICIO.pdf.txt3c88241211d0523c7bcbc60a8fe03dbfMD52THUMBNAILBECK, SILVIO MAURICIO.pdf.jpgBECK, SILVIO MAURICIO.pdf.jpgIM Thumbnailimage/jpeg5063http://repositorio.ufsm.br/bitstream/1/7721/3/BECK%2c%20SILVIO%20MAURICIO.pdf.jpg44cf1925dfceb9b89dbc5edcc03e7596MD531/77212022-01-31 15:00:50.305oai:repositorio.ufsm.br:1/7721Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-01-31T18:00:50Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |

The use of byproducts and industrial waste as pozzolanic, is an alternative to achieve the sustainability, economy and durability in concrete structures. This survey has as its purpose to analyze the effect on mechanical, elastic and deformation properties on concrete with a high level of granulated slag from blast furnace and fly ash in place of Portland bulk cement. The use of high levels of mineral additions has the purpose of increasing the durability and reducing the consumption of cement, the use of hydrated lime aims to activating these adittions, restore part of the calcium hydroxide consumed by the pozzolanic reactions, increasing the initial and final strength to the mixtures. This way, three mixtures of concrete have been studied: one of them without mineral additions, only using Portland cement (CP V-ARI), taken as a control, with relations a/c 0.40, 0.60 and 0.83, and two mixtures with mineral additions in place of cement in equal mass, with 70% of slag and 20% of fly ash, being one of them with addition of 20% of hydrated lime on the mass of binders in addition to the cement, both to the relations a/mc 0.30/0.33, 0.40 and 0.49, which have been renamed as R, EV and EVC. Tests were held to resistance to axial compression in bodies of evidence (10x20cm) the ages of 07 28, 91 and 300 days, whose results range from 18.2 MPa and 81 MPa, tests of resistance to traction by diametral compression and module of elasticity at 28, 91 and 300 days, as well as tests of total shrinkage on prismatic bodies of evidence (10x10x30 cm) at 28, 91, 180 and 300 days. The results of mechanical, elastic and strain resistance have been also correlated with some intervening and independent variables, as well as some existing regulatory requirements. The results have been analyzed to each trace individually, in relation to the control traces, in relation to the evolution of the resistance, effectiveness of the use of the hydrated lime and in equal relationship a/mc 0.4. In the analysis of the equal relationship a/mc 0.400, in the case of reference concrete, in the initial age, the resistance to the axial compression of the concrete EV was, in media, 72% of the one presented by it, being the resistance to the EVC 55%, and in the final age, 65% and 50% respectively. In the case of the traction by diametral compression, to 28 days the concrete EV presented 76% of the resistance of the reference, and the concrete EVC 58%. This relation to 300 days was 80% and 61% respectively. To the elasticity module, to 28 days, the concrete EV presented 82% and the EVC 70% of the result obtained by the reference mixture, maintaining this proportion until the final age (300 days). In the analysis of the total retraction, the concrete EV presented an inferior retraction 10% inferior to the reference trace, while the concrete EVC to 300 days presents a good retraction 16% superior to it. The observation through the conjuncture of the results found shows a satisfactory relation among the different traces studied, making feasible the use of high levels of mineral additions in substitution to the large portion of cement in bulk. |
