Use of Bioproducts Derived from Mixed Microbial Cultures Grown with Crude Glycerol to Protect Recycled Concrete Surfacesconstruction and demolition waste (CDW)waterproofPHA-producing MMCsurface treatmentrecycled concreteglycerolProject BIA2017-83526-R UID/QUI/50006/2020The large increase in the world population has resulted in a very large amount of construction waste, as well as a large amount of waste glycerol from transesterification reactions of acyl glycerides from oils and fats, in particular from the production of biodiesel. Only a limited percentage of these two residues are recycled, which generates a large management problem worldwide. For that reason, in this study, we used crude glycerol as a carbon source to cultivate polyhydroxyalkanoates (PHA)-producing mixed microbial cultures (MMC). Two bioproducts derived from these cultures were applied on the surface of concrete with recycled aggregate to create a protective layer. To evaluate the effect of the treatments, tests of water absorption by capillarity and under low pressure with Karsten tubes were performed. Furthermore, SEM-EDS analysis showed the physical barrier caused by biotreatments that produced a reduction on capillarity water absorption of up to 20% and improved the impermeability of recycled concrete against the penetration of water under pressure up to 2.7 times relative to the reference. Therefore, this bioproduct shown to be a promising treatment to protect against penetration of water to concrete surfaces increasing its durability and useful life.DQ - Departamento de QuímicaLAQV@REQUIMTEUCIBIO - Applied Molecular Biosciences UnitCERIS - Polo NOVADEC - Departamento de Engenharia CivilRUNSerrano-González, LorenaMerino-Maldonado, DanielGuerra-Romero, Manuel IgnacioMorán-Del Pozo, Julia MaríaLemos, Paulo CostaPereira, Alice SantosFaria, PaulinaGarcía-González, JuliaJuan-Valdés, Andrés2022-02-01T03:30:59Z2021-04-192021-04-19T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article13application/pdfhttp://hdl.handle.net/10362/131974eng1996-1944PURE: 29660467https://doi.org/10.3390/ma14082057info: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:RCAAP2024-03-11T05:10:35Zoai:run.unl.pt:10362/131974Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:47:17.994225Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
