Resumo: | Metakaolinis the principal raw material utilized in the synthesis of geopolymers, although its ratio of silica and alumina contents is not ideal. Normally, the SiO2 content is adjusted with the use of silicates present in the activating solution. An eco-efficient alternative would be the use of glass waste as an additional source of silica.This work evaluates the efficiency of the alkaline activation of metakaolin, using potassium hydroxide and silicate, with and without the substitution of 12.5% of metakaolin by microparticles of glass. The efficiency of the alkaline activation was evaluated by X ray diffractometry, spectroscopy in the infrared region with the Fourier transform, nuclear magnetic resonance spectroscopy of 27Al and 29Si, specific mass and compressive strength. The results indicate the occurrence of geopolymerization with and without the use of glass waste. It was observed that the substitution of 12.5% favors the mechanical performance of the compounds at 28 days, with increases by 37% and 47% in the mechanical strength of the material with thermal curing and ambient temperature curing, respectively. |

Normalmente, o teor de SiO 2 é ajustado com o uso de silicatos presentes na solução ativadora. Uma opção ecoeficiente seria o uso de resíduos de vidro como fonte adicional de sílica. Este trabalho avalia a eficiência da ativação alcalina do metacaulim, utilizando hidróxido e silicato de potássio, com e sem substituição de 12,5% de metacaulim por micropartículas de vidro. A eficiência da ativação alcalina foi avaliada por difratometria de raios x, espectroscopia na região infravermelha com transformada de Fourier, espectroscopia de ressonância magnética nuclear do 27 Al e 29 Si, massa específica e resistência à compressão. Os resultados indicam a ocorrência de geopolimerização com e sem uso de resíduo de vidro. Observou-se que a substituição de 12,5% favorece o desempenho mecânico dos compósitos aos 28 dias, com aumentos de 37% e 47% da resistência mecânica do material com cura em estufa e na temperatura ambiente, respectivamente.engUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASENG - DEPARTAMENTO DE ENGENHARIA MATERIAIS E DA CONSTRUÇÃO CIVILENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAAmbiente ConstruídoMetacaulimRefugo de vidroPotássioGeopolímerosMetakaolinGlass wastePotassium hydroxideAlkaline activationGeopolymerizationUse of glass waste in the production of metakaolin-based geopolymer submitted to room temperature and thermal curingUtilização de resíduo de vidro na produção de geopolímero de base metacaulim submetido a cura ambiente e em estufainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/ac/a/qhSXXMjVH88CQJGFzzzvwnt/?lang=en#Cristiane do Bom Conselho Sales AlvarengaRosemary do Bom Conselho SalesRodrigo Barreto CaldasPaulo Roberto CetlinMaria Teresa Paulino Aguilarapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/60683/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALUse of glass waste in the production of metakaolin-based geopolymer submitted to room temperature and thermal curing.pdfUse of glass waste in the production of metakaolin-based geopolymer submitted to room temperature and thermal curing.pdfapplication/pdf1553451https://repositorio.ufmg.br/bitstream/1843/60683/2/Use%20of%20glass%20waste%20in%20the%20production%20of%20metakaolin-based%20geopolymer%20submitted%20to%20room%20temperature%20and%20thermal%20curing.pdfd894396603b517ae9cde9814734549efMD521843/606832023-11-08 19:24:04.877oai:repositorio.ufmg.br:1843/60683Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-08T22:24:04Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
