I. Gomes was supported by a doctoral grant from the Portuguese Foundation for Science and Technology (FCT) with the reference SFRH/BD/48394/2008. The work is within RILEM Technical Committee TCE - Testing and Characterisation of Earth-based building materials and elements and projects PTDC/EPH-PAT/4684/2014: DB-HERITAGE - Data base of building materials with architectural heritage and historic importance and 23349–02/SAICT/2016 – INDEED: Indoor air quality regulation through the usage of eco-efficient mortars.Repairs in rammed earth walls are often necessary mainly because of degradation occurring during the life time of a building with continuous environmental exposure. The defects that arise in the walls are generally associated with loss of its thickness, on the surface or in greater depth. They must be repaired with a mortar technically efficient and compatible with the rammed earth, to ensure protection and, as possible, long-term durability. The present study describes and discusses the adequacy of earth-based mortars to repair unstabilized rammed earth walls and the behaviour of the systems rammed walls-earth repair mortars when subjected to accelerated aging tests by wetting-drying cycles. Even under aggressive capillarity tests, the results observed corroborate that unstabilized earth repair mortars behave better in comparison to similar mortars with additions of low amounts of different inorganic binders.CERIS - Polo NOVADEC - Departamento de Engenharia CivilRUNGomes, Maria IdáliaFaria, PaulinaGonçalves, Teresa Diaz2023-03-02T01:32:08Z2019-04-302019-04-30T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article19application/pdfhttps://doi.org/10.1016/j.conbuildmat.2019.01.222eng0950-0618PURE: 11551115http://www.scopus.com/inward/record.url?scp=85061151421&partnerID=8YFLogxKhttps://doi.org/10.1016/j.conbuildmat.2019.01.222info: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:RCAAP2024-03-11T04:31:12Zoai:run.unl.pt:10362/65500Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:34:21.662706Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
