Use of mixed microbial cultures to protect recycled concrete surfacesA preliminary studyConstruction and demolition waste (CDW)Mixed microbial cultures (MMCs)Polyhydroxyalkanoates (PHAs)Recycled concreteSurface treatmentWaterproofMaterials Science(all)Condensed Matter PhysicsBIA2017-83526-R UID/QUI/50006/2020One approach to tackle the problems created by the vast amounts of construction and demolition waste (CDW) generated worldwide while at the same time lengthening concrete durability and service life is to foster the use of recycled aggregate (RA) rather than natural aggregate (NA). This article discusses the use of polyhydroxyalkanoates (PHAs)-producing mixed microbial cultures (MMCs) to treat the surface of recycled concrete with a view to increase its resistance to watermediated deterioration. The microorganisms were cultured in a minimal medium using waste pinewood bio-oil as a carbon source. Post-application variations in substrate permeability were determined with the water drop absorption and penetration by water under pressure tests. The significant reduction in water absorption recorded reveals that this bioproduct is a promising surface treatment for recycled concrete.DQ - Departamento de QuímicaLAQV@REQUIMTEUCIBIO - Applied Molecular Biosciences UnitCERIS - Polo NOVADEC - Departamento de Engenharia CivilRUNSerrano-González, LorenaMerino-Maldonado, DanielGuerra-Romero, Manuel IgnacioPozo, Julia María Morán DelLemos, Paulo CostaPereira, Alice SantosFaria, PaulinaGarcía-González, JuliaJuan-Valdés, Andrés2021-11-24T23:39:01Z2021-11-012021-11-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/128223eng1996-1944PURE: 35023023https://doi.org/10.3390/ma14216545info:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-22T17:57:18Zoai:run.unl.pt:10362/128223Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T17:28:15.692731Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse |
