Item Produção de concretos com resíduos de poliuretano triturado em substituição ao agregado miúdo(2021-12-08) Pereira, Wesley Batista; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/7022069132421368The reuse of potential materials that would otherwise be sent to landfills or stored in incorrect locations, contributing to the pollution of water courses and influencing the sewage system of cities and the most varied damages to the environment and the population, is a reality each more current. Among these materials, the polyurethane polymer (PU) stands out in its many variations, where its reintroduction into the production chain brings socio-environmental advantages. This article presents a comparative analysis between a mix of conventional concrete and concretes with partial replacements of fine aggregate by crushed expanded polyurethane waste, from refrigerator scrap, in 5% and 10% contents, replaced in relation to the volume of the sand, this procedure was also performed for a mix with the addition of silica fume. Two pilot traces were developed, one with silica (CS) and one without silica (SS). The properties of the concrete produced were evaluated through the slump test of the cone trunk (NBR 16889: 2020), analysis of compressive strength (NBR 5739: 2018), tensile strength by diametrical compression (NBR 7222:2011), mass specific and water absorption (NBR 9778:2005). The results obtained from this study demonstrate that the increase in the amount of PU foam in concrete reduced significantly the specific mass and reduced the mechanical strength of the part. It is noteworthy that the use of silica fume can be a differential in the production of concrete with recycled aggregates such as expanded PU foam, so that the resistances are maintained.Item Projeto de reuso de água pluvial em habitação popular para fins não potáveis(2019-12-12) Cruz, Ana Vitória de Souza; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1049768443014317Strong population growth and urbanization have led to increased drinking water consumption. This factor, coupled with irresponsible use and pollution of water sources, has contributed to a considerable water crisis. Brazil is a privileged country, as it has 12% of the world's freshwater, but due to poor distribution, there are regions of the country where water availability is low, such as the Northeast of Brazil that faces severe scarcity crises most of the year. Therefore, the search for sustainable policies that provide solutions to this problem and at the same time make the population aware of the importance of conscious use of water is necessary. Within this context, the reuse of rainwater becomes a viable alternative, easily applied, which provides the preservation of the environment. Therefore, the present work elaborated a popular housing project in Recife based on the city's Master Plan and designed a Rainwater harvesting System for this dwelling, according to NBR 10844 (1989). In the project, the rainwater was captured only by water from the roof, which enough to meet the house reuse needs, as the city has a high rate of rainfall. The materials used in the installation of the collection system were low cost and simple to apply, where the implementation project presented a much lower cost than the total value of residential construction, besides representing an excellent alternative for environmental awareness and treated water saving
