“…A number of papers dealing with the experimental characterization of concrete mixtures employing different kinds of recycled aggregates have been published in the last few years [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In fact, Behiry [13] showed that by mixing recycled concrete aggregate (RCA) with traditional limestone aggregate (LSA), the mechanical properties of the mixture can be improved, taking the unconfined compressive strength as a quality indicator.…”

“…Specific treatments by using low concentration acid, aimed at producing high quality RCA for structural concrete applications, are under investigation [14]. Waste polyethylene terephthalate (PET) is deemed promising by the scientific community as an alternate binding material in place of the commonly used ordinary Portland cement, and it is also studied together with composite structures [15][16][17][18][19]. Furthermore, experimental data are often accompanied by numerical analysis in order to investigate the mechanical behavior of RCA structures [17,20].…”

Abstract:The correct estimation of building energy consumptions is assuming an always increasing importance, and a detailed reproduction of building structures, with all the single components involved, is necessary to achieve this aim. In addition, the current ecological development tries to limit the use of natural raw materials as building components, in favor of alternative (waste) materials, which ensure significant advantages from the economic, energetic and environmental point of views. In this work, dynamic heat and vapor transport in a typical three-dimensional (3D) building structure, involving different types of environmental-friendly concrete mixtures, have been simulated by using finite elements. In particular, the authors propose to substitute part of the aggregates with plastic waste and to use a fly ash based geopolymeric binder for the production of low conductivity concrete, to be employed in eco-efficient buildings. Concrete produced with natural limestone aggregates has been considered as the reference benchmark. The whole characterization of the different types of concrete tested in the present work has been obtained through laboratory experiments. The structure taken into account in the simulations is a 3D thermal bridge, typical of building envelopes. The thermal and hygrometric transient behavior of this structure, employing plastic waste in different percentages and geopolymer concrete, has been analyzed by the authors.

“…Além disso, sugere-se que as adições de retardante de chamas agregaram aos compósitos uma De qualquer maneira, vale salientar que, apesar das perdas de resistência à tração na flexão ocorridas após a submissão das amostras à temperatura de 325°C, os valores remanescentes, após permanência em forno, encontram-se próximos aos valores apresentados nos estudos consultados (REBEIZ, 1995;DAL MOLIN;KAZMIERCZAK, 2007;RODRIGUES, 2007;KAZMIERCZAK, 2008, JO;PARK;PARK, 2008), salientando-se que os mesmos não foram submetidos ao calor nestas pesquisas.…”

Resumostes compósitos exibem excelentes propriedades mecânicas, mas devem ser adaptados às propriedades de combustibilidade. O estudo teve como objetivo, produzir concretos poliméricos utilizando alumina residual, como retardante de chamas, originados do beneficiamento industrial metalúrgico. Os compósitos tem como aglomerante a resina poliéster ortoftálica reciclada a partir do PET, como agregados foi adotada a areia de rio e a cinza volante como fíler. Foram utilizados dois tipos de retardantes de chama: um resíduo, a alumina de polimento, e o outro virgem, alumina comercial em quatro diferentes percentagens de 15, 30, 45 e 60% em massa, em relação à resina. As amostras foram submetidas ao ensaio de resistência tração na flexão e de resistência às temperaturas de 125, 225 e 325 °C. Os resultados tiveram tratamento estatístico, a fim de avaliar o nível de significância das variáveis em relação às propriedades estudadas. Os valores de resistência à tração na flexão atingiram os 30 MPa. A análise estatística mostrou que os fatores, mudanças de temperatura, percentual de adição e da interação entre esses fatores, mostraram grande influência sobre as composições estudadas em relação à resistência às temperaturas elevadas. Em termos gerais, pode dizer-se que, o retardante de chamas residual, alumina de polimento, é uma alternativa eficiente para substituir a alumina trihidratada comercial em compósitos poliméricos de resina poliéster.

“…It is the durability and resistance against corrosion of construction materials that are the characteristics considered in recent years as the chief aim of the research into the process of modifying the existing materials and/or producing new composites of improved properties. Numerous research institutions have been conducting long-term research into the fabrication of new polymer concretes that can be successfully used for protecting structures against the harmful influence of aggressive agents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
