Resumo: | The objective of the present study was to evaluate the effect of using different types and compositions of materials with insulating characteristics in the production of concrete tiles, in order to improve the physical, mechanical and thermal characteristics of the tiles. The insulating materials used were vermiculite in proportions of 5% (TAV5) and 10% (TAV10), polystyrene in the proportion of 5% (TAI5 )and additive incorporated with air in proportions of 5% (TAA5). Tests were conducted to determine the physical properties (dimensions, water absorption and permeability), mechanical (flexural strength at break) of thermal and concrete tiles. The physical, mechanical and thermal of different tiles were compared to data obtained from the reference tile (TAN) and evaluated based on the minimal criteria established by the NBR 13.858:2 (ABNT, 2009). Based on the results of the physical properties, it was found that all treatments met the requirements of the relevant standard in the country. As regards the mechanical properties, various tiles in the flexural tensile strength was lower than the recommended minimum. The incorporation of materials with insulating characteristics of concrete tiles showed good efficiency in reducing the temperature of the tiles. |

Os materiais isolantes usados foram: vermiculita em proporções de 5% (TAV5) e 10% (TAV10), poliestireno em proporções de 5% (TAI5) e aditivo incorporador de ar em proporções de 5% (TAA5). Testes foram realizados para determinação das propriedades físicas (dimensões, absorção de água e permeabilidade), mecânicas (resistência à ruptura por flexão) e térmicas das telhas de concreto. As propriedades físicas, mecânicas e térmicas das diferentes telhas foram comparadas às determinadas na telha testemunha (TAN), preparada com concreto normal, e avaliadas com base nos critérios mínimos estabelecidos pela NBR 13.858:2 (ABNT, 2009). Com base nos resultados das propriedades físicas, verificou-se que todos os tratamentos testados atenderam aos requisitos exigidos pela norma pertinente no país. No que se refere à propriedades mecânicas, nas diferentes telhas a carga de ruptura à flexão foi inferior ao mínimo recomendado. A incorporação de materiais com características isolantes em telhas de concreto apresentou boa eficiência na redução da temperatura da face interna das telhas.Universidade Federal de Viçosa - UFV2015-11-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/52310.13083/reveng.v23i5.578Engineering in Agriculture; Vol. 23 No. 5 (2015); 406-417Revista Engenharia na Agricultura - REVENG; v. 23 n. 5 (2015); 406-4172175-68131414-398410.13083/reveng.v23i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/523/360Damasceno, Flavio AlvesMacedo, Otávio Assunção Peitode Oliveira, Jofran LuizOliveira, Carlos Eduardo AlvesBrandão, Leidimar Freireinfo:eu-repo/semantics/openAccess2023-01-19T13:22:46Zoai:ojs.periodicos.ufv.br:article/523Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:22:46Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
