Effectiveness of mortars composition on the embodied carbon long-term impactEmbodied carbon expenditureLCAPerformance based-designRendering mortarsThe authors of this paper also wish to acknowledge the FCT- Fundação para a Ciência e a Tecnologia, Portugal, for the grant support (SFRH/BPD/111183/2015) that ensures the development of this project.Refurbishment activities represent more than 17% of the saving potential of the EU up to 2050. However, studies on buildings structure and finishing reparation of rendering mortars using LCA are still lacking. An innovative design approach is required to drive the minimisation of embodied carbon using objective performance information of buildings behaviour. This research work is focused on the reparation of rendering mortars and intends to demonstrate that the choice of mortars for buildings affects the maintenance actions needed and can increase the construction environment liability and embodied carbon expenditure. A new leaching risk analysis combined with LCA of different mortars composition (cement and lime based) was implemented enabling to predict the longevity of the rendering and the embodied carbon expenditure on 20th century buildings. It is demonstrated that some mortars may have a higher impact at the outset, such as cement-based mortars, but result in a much lower impact across the building service life. The embodied carbon of repair actions of mortars similar to OPC are expected to reduce the environmental impact of rendering repair actions at least in 10 times in comparison to less hydraulic mortars.DEC - Departamento de Engenharia CivilRUNBrás, AnaFaria, Paulina2022-03-12T01:31:25Z2017-11-012017-11-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article6application/pdfhttp://hdl.handle.net/10362/28789eng0378-7788PURE: 3161451https://doi.org/10.1016/j.enbuild.2017.08.026info: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:RCAAP2024-03-11T04:15:32Zoai:run.unl.pt:10362/28789Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:29:03.331947Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
