Item Desenvolvimento de ferramenta computacional para o dimensionamento de blocos de ancoragem para tubulações sob pressão(2021-12-10) Medeiros, Khrys Kathyllen da Silva de; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/5605761011467421Thrust blocks for pressurized pipelines are concrete blocks designed to resist the applied forces, mainly due to hydraulic thrust. In many situations, a thrust block is required to ensure the safety of the pipeline, therefore, it is necessary the verifications are carried out correctly to prove those elements’ stability and efficiency. In order to develop a computational tool to help in the thrust elements design and safety verification for pressurized pipelines, a computational software named ProBlocos was developed. The tool interface is divided into three main areas: input data, result report and thrust block sketch. Real blocks from academic research were used to carry out tests and check the results obtained by the created software. The results showed that the developed program is low-cost, simple and effective to aid in the development of pressure pipeline projects. Thereby, the proposed work can be used by engineering professionals and students, regardless of the user's familiarity with the computer language used.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.
