Resumo: In this investigation, the properties of ultra-high-performance concretes (UHPC) produced with different binders and aggregates were analyzed. Ternary and quaternary mixtures were tested, including structural white Portland cement (WPC), silica fume (SF), hydrated lime (HL), rice husk ash (RHA), fly ash (FA), and limestone filler (LF), in combination with industrial sand (IS) and discarded foundry phenolic sand (DFPS). The mixtures underwent two types of curing: moist curing until the testing age and moist combined with thermal curing. The concretes were evaluated for compressive strength and microstructure using thermogravimetric analysis (TG/DTG) and Fourier transform infrared spectroscopy (FTIR) techniques. The results showed that all mixtures achieved the desired levels of strength for UHPC (150 MPa). Up to 28 days, the mixtures with RHA exhibited higher strength compared to those with FA, regardless of the curing type. However, at 91 days, the mixtures with FA and thermal curing were more resistant than the mixtures with RHA. Among the quaternary mixtures, at 7 days, the strengths of the mixtures were equivalent, indicating that FA did not react at earlier ages.

En este estudio, se ha buscado producir CUAD utilizando arena de desecho de fundición fenólica (PFS). Se ensayaron cinco mezclas de hormigón. Un CUAD de referencia, denominado REF, con un 85% de cemento Portland blanco (WPC) y un 15% de humo de silica (SF) como ligantes, y áridos en una proporción de 36% polvo de cuarzo y 84% arena industrial. Y cuatro mezclas eco-amigables con adiciones minerales: RHA15, con 85% WPC y 15% RHA; FA15, con 85% WPC y 15% FA; RHA10-FA5, con 85% WPC, 10% RHA y 5% FA; y RHA10-LF5, con 85% WPC, 10% RHA y 5% LF. A excepción de la mezcla REF, todas las demás mezclas tenían la adición de un 15% de cal, tipo CH I, junto con áridos compuestos por un 36% de polvo de cuarzo y un 84% de arena fenólica (PFS). La relación agua/ligante adoptada fue de 0,20 para todas las mezclas. Nesta investigação, foram analisadas as propriedades dos concretos de ultra alto desempenho (CUAD) produzidos com diferentes aglomerantes e agregados. Foram testadas misturas ternárias e quaternárias, com cimento Portland branco estrutural (CPB), sílica ativa (SA), cal hidratada (CH I), cinza de casca de arroz (CCA), cinza volante (CV) e fíler calcário (FC), em combinação com areia industrial (AI) e areia fenólica de descarte de fundição (ADF). As misturas foram submetidas a dois tipos de cura: úmida até a idade de ensaio e úmida combinada com cura térmica. Os concretos foram avaliados quanto à resistência à compressão axial e à microestrutura utilizando técnicas de análise termogravimétrica (TG/DTG) e espectroscopia de infravermelho por transformada de Fourier (FTIR). Os resultados mostraram que todas as misturas atingiram níveis de resistência desejados para CUAD (150 Mpa). Até 28 dias, as misturas com CCA apresentaram maior resistência em comparação com as misturas com CV, independentemente do tipo de cura. Contudo, aos 91 dias, as misturas com CV e cura térmica foram mais resistentes que as misturas com CCA. Entre as misturas quaternárias, aos 7 dias, as resistências das misturas foram equivalentes, indicando que a CV não reagiu nas idades inferiores.UFSC - Federal University of Santa Catarina2023-10-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/618910.29183/2447-3073.MIX2023.v9.n5.183-199Mix Sustentável; Vol. 9 No. 5 (2023): Mix Sustentável (edição regular); 183-199MIX Sustentável; v. 9 n. 5 (2023): Mix Sustentável (edição regular); 183-1992447-30732447-0899reponame:Mix Sustentável (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/6189/5776InternacionalInternacionalInternacionalCopyright (c) 2023 Bóris Casanova Sokolovicz, André Lübeck, Geraldo Cechella Isaia, Heliton Weidehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCasanova Sokolovicz, Bóris Lübeck, AndréCechella Isaia, Geraldo Weide, Heliton2024-04-25T19:49:47Zoai:ojs.sites.ufsc.br:article/6189Revistahttp://mixsustentavel.paginas.ufsc.br/apresentacao-2/PUBhttp://ojs.sites.ufsc.br/index.php/mixsustentavel/oailisiane.librelotto@ufsc.br||mixsustentavel@gmail.com2447-30732447-0899opendoar:2024-04-25T19:49:47Mix Sustentável (Online) - Universidade Federal de Santa Catarina (UFSC)false
