Resumo: Several requirements and challenges of modern construction motivated the development of High-Performance Concrete (HPC) and later, with the advance of the research, the Ultra-High Performance Concrete (UHPC). Due to the seek for a concrete that was not only higher in compressive strength, but also with good tensile and ductility behavior, self-compacting, and very high durability. Composed primarily by portland cement, silica fume, quartz powder, small aggregate, steel fibers, super plasticizing additives and water, UHPC first research was developed around 1990 in France and Canada. This material can reach high strength, in the range of 150 MPa to 800 MPa for compression and 5 MPa to 100 MPa for tension, with high ductility. These characteristics allow more durable and slender structures. In addition, there is the possibility to reduce or eliminate the passive reinforcements, in particular shear. The aim of this work is to introduce criteria for structural design using UHPC, as well as its composition, production, curing methods and the main factors that hinder its use in a greater number of constructions. This text organizes all relevant information on the topic, developing a material capable of guiding engineers in the design of structures using this technology, and with that, to encourage their use in the various fields of the civil construction industry in Brazil. The research is composed by a literature review including research already developed on the subject in Brazil and in several other countries, describing the main constructions already executed with this material, design criteria, constructive details and the characteristics that differs it from conventional concretes. As application examples, prestressed bridge girder beam designs are developed using the CUAD and compared with prestressed concrete design using conventional concrete for a feasibility analysis. With the study, it was possible to clearly expose all the information necessary for its design, production and structural application, in addition to providing a material capable of guiding the design of structures using UHPC and also serving as a contribution to future technical normalization.

Diversas exigências e desafios da construção moderna motivaram o desenvolvimento do Concreto de Alto Desempenho (CAD) e, posteriormente, com o avanço das pesquisas o Concreto de Ultra Alto Desempenho (CUAD), buscando um material que fosse não somente de alta resistência à compressão, mas que também tivesse boa resistência à tração, ductilidade, autoadensável e com altíssima durabilidade. Composto basicamente por cimento portland, sílica ativa, pó-de-quartzo, agregado miúdo, fibras de aço, aditivos superplastificantes e água, o CUAD surgiu por meio de pesquisas desenvolvidas por volta de 1990 na França e no Canadá. Esse material pode atingir elevadas resistências, numa faixa entre 150 MPa a 800 MPa à compressão e de 5 MPa a 100 MPa à tração, apresentando grande ductilidade. Essas características viabilizam estruturas mais duráveis e com elevada esbeltez, além de possibilitar a redução ou eliminação de armaduras passivas, em especial estribos para resistir ao cisalhamento. Este trabalho tem por objetivo descrever e indicar critérios para projeto de aplicação estrutural utilizando a tecnologia do CUAD, assim como sua composição, produção, métodos de cura e os principais fatores que impedem ou dificultam sua utilização em maior número de obras. Busca-se reunir todas as informações relevantes, desenvolvendo um material capaz de nortear projetistas no dimensionamento de estruturas aplicando essa tecnologia, e com isso, incentivar seu uso nos diversos campos da indústria da construção civil no Brasil. A pesquisa é composta de uma revisão da literatura por meio de pesquisas já desenvolvidas sobre o assunto no Brasil e em vários outros países, descrevendo as principais obras já executadas com esse material e as características que o difere dos concretos convencionais. Como exemplos de aplicação, foram realizados dimensionamentos de vigas protendidas para pontes utilizando o CUAD e comparadas com dimensionamento em concreto protendido utilizando concreto convencional para uma análise de viabilidade. Com o trabalho, foi possível expor de maneira clara todas as informações necessárias para sua produção e aplicação de forma estrutural, além de propor um material capaz de orientar no dimensionamento de estruturas aplicando-se o CUAD e, também, que sirva de contribuição para uma futura normalização técnica.Não recebi financiamentoporUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Engenharia Civil - PPGECivUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessConcretoCUADCADConcreto protendidoCRFConcreteUHPCHPCPrestressed concreteFRCENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURASAplicação do concreto de ultra alto desempenho em viga pré-moldada protendida para pontesApplication of prestressed ultra high-performance concrete in precast bridge girderinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis600600cc830dc1-debc-4e7f-bbc7-a442aa405614reponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissertação Mestrado Jadson - UFSCar.pdfDissertação Mestrado Jadson - UFSCar.pdfapplication/pdf8065418https://repositorio.ufscar.br/bitstream/ufscar/15317/1/Disserta%c3%a7%c3%a3o%20Mestrado%20Jadson%20-%20UFSCar.pdf495d614bb3168586fad1378bc146c392MD51Carta_Aprovacao.pdfCarta_Aprovacao.pdfCarta de Aprovação assinada pelo Orientadorapplication/pdf105270https://repositorio.ufscar.br/bitstream/ufscar/15317/3/Carta_Aprovacao.pdf6907f8ab7dfcbf3ae58570a09d86bc23MD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8811https://repositorio.ufscar.br/bitstream/ufscar/15317/4/license_rdfe39d27027a6cc9cb039ad269a5db8e34MD54TEXTDissertação Mestrado Jadson - UFSCar.pdf.txtDissertação Mestrado Jadson - UFSCar.pdf.txtExtracted texttext/plain381714https://repositorio.ufscar.br/bitstream/ufscar/15317/5/Disserta%c3%a7%c3%a3o%20Mestrado%20Jadson%20-%20UFSCar.pdf.txt2c9a2053379f105af9077c67ce29861cMD55Carta_Aprovacao.pdf.txtCarta_Aprovacao.pdf.txtExtracted texttext/plain1224https://repositorio.ufscar.br/bitstream/ufscar/15317/7/Carta_Aprovacao.pdf.txt55e0cad72fdd13b01bde97a3e03648dbMD57THUMBNAILDissertação Mestrado Jadson - UFSCar.pdf.jpgDissertação Mestrado Jadson - UFSCar.pdf.jpgIM Thumbnailimage/jpeg6484https://repositorio.ufscar.br/bitstream/ufscar/15317/6/Disserta%c3%a7%c3%a3o%20Mestrado%20Jadson%20-%20UFSCar.pdf.jpg323cad744b8a062ee7727ec3b95dceddMD56Carta_Aprovacao.pdf.jpgCarta_Aprovacao.pdf.jpgIM Thumbnailimage/jpeg14477https://repositorio.ufscar.br/bitstream/ufscar/15317/8/Carta_Aprovacao.pdf.jpgc279386db650a8705f46c708d754e934MD58ufscar/153172023-09-18 18:32:25.015oai:repositorio.ufscar.br:ufscar/15317Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:32:25Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false
