O objetivo foi avaliar o desempenho das argamassas colantes baseado nas características dos polímeros e do percentual de cimento aplicado, a fim de verificar a sua flexibilidade para uso em fachadas expostas às variações climáticas e bastante solicitadas pelas deformações estruturais. Os testes das amostras foram limitados aos ensaios normativos, mas, a partir da escolha de quatro variações, a análise do tempo em aberto e sua extensão de aderência foram relevantes para o aprofundamento do estudo que consistiu no desenvolvimento de uma argamassa para uso específico em fachadas. Os resultados das quatro variações foram satisfatórios em suas forças de adesão para a classificação dessas amostras do tipo ACII de acordo com os critérios normativos brasileiros. A partir dos resultados obtidos nos testes de deformabilidade verificou-se que, independentemente dos tipos de polímeros adicionados às composições, as argamassas colantes podem demonstrar maior deformabilidade adicionando um polímero com sua temperatura de transição vítrea mais próxima da temperatura ambiente medida durante o teste, equilibrando com a dosagem de cimento para um melhor desempenho da argamassa colante em sua interface com a cerâmica, a fim de ser verificado, após estudos, quanto às exigências de durabilidade em função de sua deformabilidade.Fourteen variations of adhesive mortars were measured by varying the polymer type and combining them with cement in two different proportions, water retainer and additions, which provided the mortars with adequate consistency for application on facades. The objective was to evaluate the performance of adhesive mortars based on the characteristics of the polymers and the percentage of cement applied, in order to verify their flexibility for use in facades exposed to climatic variations and much requested by structural deformations. The tests of the samples were limited to the Brazilian technical norms, but from the choice of 4 variations, the analysis of the open time and its adhesion extension were important for the deepening of the study that consisted in the development of a mortar for use in facades. The results of the four variations were satisfactory in their adhesion forces for the classification of these samples as ACII according to the Brazilian normative criteria. From the results obtained in the deformability tests, it was found that, regardless of the types of polymers added to the compositions, adhesive mortars can demonstrate greater deformability by adding a polymer with its glass transition temperature closer to the ambient temperature measured during the test, Balancing with the cement dosage for better performance of the adhesive mortar in its interface with the ceramic, in order to verify, after studies, the durability requirements due to its deformability.porUniversidade Federal de Minas GeraisPrograma de Pós-Graduação em Construção CivilUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA MATERIAIS E DA CONSTRUÇÃO CIVILConstrução civilArgamassaFachadasRevestimentosAderênciaArgamassa colanteFachadasSistema de revestimento.Extensão de aderênciaDesenvolvimento de argamassa colante polimerizada para aplicação de revestimentos cerâmicos em fachadasinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGORIGINALDissertação Stefane Jardim Vitorino_final (1) Revisão repositório.pdfDissertação Stefane Jardim Vitorino_final (1) Revisão repositório.pdfapplication/pdf3237537https://repositorio.ufmg.br/bitstream/1843/34495/1/Disserta%c3%a7%c3%a3o%20Stefane%20Jardim%20Vitorino_final%20%281%29%20Revis%c3%a3o%20reposit%c3%b3rio.pdfff8a175ae4e4bb11bb48fbf82e699cbcMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-82119https://repositorio.ufmg.br/bitstream/1843/34495/2/license.txt34badce4be7e31e3adb4575ae96af679MD521843/344952020-12-10 17:07:55.198oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2020-12-10T20:07:55Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
