Resumo: Introduction: Geopolymers are the modern inorganic materials obtained as a result of chemical reaction under strongly alkaline conditions. The main advantages of these materials are: high strength parameters, fire resistance, frost resistance and resistance to aggressive environment. Because of lower CO2 emission during production process, they are also considered as environmentally friendly materials in comparison to ordinary Portland cement (OPC) systems. Objectives: The aim of the investigation was to define the impact of recycled ground glass addition on mechanical properties of geopolymeric binder made from tungsten mine waste. Methods: The strength parameters of geopolymeric samples were determined on the basis of three-point flexural test and uniaxial compression test. Results: The geopolymer samples that contain 20%, 40% and 80% of recycled ground glass present similar flexural strength. The compressive strength of glass-based geopolymers increases with growing content of recycled ground glass. Conclusions: In terms of flexural strength, the most favourable composition was the mixture composed of 60% recycled ground glass and 40% tungsten mine waste. In terms of compressive strength, the most favourable composition was the mixture composed of 80% recycled ground glass and 20% tungsten mine waste.

Las principales ventajas de estos materiales son: parámetros de alta resistencia, resistencia al fuego, resistencia a las heladas y resistencia al entorno agresivo. Debido a la menor emisión de CO2 durante el proceso de producción, también se consideran materiales ecológicos en comparación con los materiales ordinarios de cemento Portland. Objetivos: El objetivo de la investigación fue definir el impacto de la adición de vidrio triturado reciclado en las propiedades mecánicas del aglutinante geopolimérico a partir de desechos de la mina de tungsteno. Métodos: Los parámetros de fuerza de las muestras geopoliméricas se determinaron sobre la base de la prueba de flexión de tres puntos y la prueba de compresión. Resultados: Las muestras de geopolímeros que contienen 20%, 40% y 80% de vidrio triturado reciclado presentan una resistencia a la flexión similar. La resistencia a la compresión de los geopolímeros basados en vidrio triturado aumenta con el creciente contenido de vidrio triturado reciclado. Conclusiones: En términos de resistencia a la flexión, la composición más favorable fue la mezcla compuesta por 60% de vidrio triturado reciclado y 40% de desechos de la mina de tungsteno. En términos de resistencia a la compresión, la composición más favorable fue la mezcla compuesta de un 80% de vidrio reciclado y un 20% de desechos de la mina de tungsteno.Introdução: Os geopolímeros são os materiais inorgânicos modernos obtidos como resultado da reação química sob condições fortemente alcalinas. As principais vantagens destes materiais são: parâmetros de alta resistência; resistência ao fogo; resistência ao gelo e resistência a ambientes agressivos. Por causa da menor emissão de CO2 durante o processo de produção, eles também são considerados materiais ecológicos em comparação com materiais de cimento Portland comuns. Objetivos: O objetivo da investigação foi definir o impacto da adição de vidro moído reciclado nas propriedades mecânicas do aglomerante geopolimérico produzido a partir de resíduos de minério de tungsténio. Métodos: Os parâmetros de resistência de amostras geopoliméricas foram determinados com base no teste de flexão e teste de compressão. Resultados: As amostras geopoliméricas que contêm 20%, 40% e 80% de vidro moído reciclado apresentam resistência à flexão similar. A resistência à compressão de geopolímeros à base de vidro aumenta com o crescente conteúdo de vidro moído reciclado. Conclusões: Em termos de resistência à flexão, a composição mais favorável foi a mistura composta por 60% de vidro moído reciclado e 40% de resíduos de minério de tungsténio. Em termos de resistência à compressão, a composição mais favorável foi a mistura composta de 80% de vidro moído reciclado e 20% de resíduos de minério de tungsténio.Polytechnic Institute of Viseu (IPV)2019-01-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.29352/mill0208.01.00185eng1647-662X0873-3015Dawczyński, SzymonCieśla, PaulinaGórski, MarcinKrzywoń, Rafałinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-06-15T15:01:44Zoai:ojs.revistas.rcaap.pt:article/14167Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:29:22.887758Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
