Item Implantação de tecnologias sustentáveis na construção civil: revisão bibliográfica e estudo de caso(2024-03-01) Batista, Pedro Ivo Vilela Laet; Silva, Robson José; http://lattes.cnpq.br/7515677435963888The principle of sustainability goes beyond solving immediate problems, it represents an innovative approach to interacting with the environment through new construction practices. In this sense, several sustainable techniques have emerged as promising alternatives for the production of works. They are: sustainable drainage, collection and use of rainwater, photovoltaic panels and green facade. In this context, the present study aimed to carry out a careful bibliographical review regarding the application of these technologies in the current scenario of civil construction and their application in a case study, carrying out a financial approach through two scenarios: assessment of costs with application of technologies and assessment of costs without applying them. The case study was applied in a local unit aimed at meeting the public in a specific community. After evaluating the results, it was observed that the technologies mentioned are promising in the country, from a social, environmental and economic point of view. Furthermore, in the case study, the application of technologies resulted in an overall savings of 71.53% over the conventional costs of the project, demonstrating the financial viability for the civil construction scenario.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 Estudo comparativo entre os sistemas de drenagem convencional e sustentável para um loteamento no município de Gravatá - PE(2022-10-07) Santana, Caroline Adriele Mendonça de; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/7891435824185832As a result of disorderly population growth, increased deforestation and pollution in recent years, cities are experiencing the great challenge of dealing with rain runoff problems. Due to the soil waterproofing, problems such as flooding and inundation resulting from natural events are increasingly frequent, and in addition to it, the lack of planning in cities. To solve this problem, it is necessary to use urban drainage elements that act efficiently in the capture and adequate conduction of rainwater, reducing the negative impacts on the population and the environment. In this context, the present study made a comparative analisys between conventional and sustainable drainage systems for a subdivision in Gravatá-PE. The conventional drainage system was dimensioned with the use of gutters, storm drains, manholes, detention reservoir and culverts. The sustainable drainage system, on the other hand, was designed with partial replacement of waterproofed coatings with green areas, use of interlocked pavements, hollow blocks, infiltration trenches and a detention reservoir with a permeable bed. The results showed that the increase in green area, in addition to providing environmental comfort, also contributed to the reduction of surface runoff, reducing the risk of floods and waterlogging. Besides, by providing greater infiltration of water into the soil, sustainable drainage showed savings in the use of devices. Therefore, the study showed that the adoption of sustainable measures, from the conception to the execution of the projects, can be the solution to the current problems faced regarding urban drainage.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
