Resumo: | Considering the European targets for energy efficiency and decarbonization, without compromising thermal comfort, it’s necessary to define more efficient and sustainable air conditioning solutions, in terms of design, use of materials and even system efficiency. Improving the thermal properties of mortars used in underfloor heating systems is a promising strategy for increasing the thermal and energy efficiency of these systems, which have gained market share not only in northern and central Europe, but also in North America. The thermal and energy efficiency of hydraulic underfloor heating systems depends of the geometry and constitution of the layers, the materials used and the operating conditions, with a great impact on the thermophysical properties of the mortar used to surround the pipes. From a perspective of valuing industrial waste as a specific contribution for sustainability in construction, the object of study of this work is the incorporation of an Inert Steel Aggregate for Construction (ASIC) as a partial substitute for the natural aggregate of a self-levelling fluid mortar to improve its performance in underfloor heating systems. In addition to the thermal and mechanical characterization of mortars with different ASIC contents, the performance of mortars in this type of application was also measured using a calibrated numerical model. |

A melhoria das propriedades térmicas das argamassas utilizadas nos sistemas de pavimento radiante é uma estratégia promissora para o aumento da eficiência térmica e energética destes sistemas que têm ganho quota de mercado não só no norte e centro da Europa, bem como na América do Norte. A eficiência térmica e energética dos sistemas de pavimento radiante hidráulicos é dependente da geometria e constituição das camadas, dos materiais empregues e das condições de operação, tendo grande impacto as propriedades termofísicas da argamassa utilizada para envolver as tubagens. Numa perspetiva de valorização de um resíduo industrial como contributo específico para a sustentabilidade na construção, é objeto de estudo deste trabalho a incorporação de um Agregado Siderúrgico Inerte para a Construção (ASIC) como substituto parcial do agregado natural de uma argamassa fluída autonivelante para melhorar o seu desempenho em sistemas de pavimento radiante. Para além da caracterização térmica e mecânica de argamassas com diferentes teores de ASIC, o desempenho das argamassas neste tipo de aplicação foi também aferido através de um modelo numérico calibrado.CTAC2023-12-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.21814/ecum.5547https://doi.org/10.21814/ecum.5547Engenharia Civil UM; Nº 66 (2023); 6-13Engenharia Civil UM; Nº 66 (2023); 6-132795-59820873-1152reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://revistas.uminho.pt/index.php/ecum/article/view/5547https://revistas.uminho.pt/index.php/ecum/article/view/5547/6225Figueira, A.Rebelo, F.Paiva, H.Figueiredo, A.Almeida, R.Vicente, R.Ferreira, V.info:eu-repo/semantics/openAccess2024-01-06T09:20:18Zoai:journals.uminho.pt:article/5547Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T01:30:33.963292Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
