Resumo Este estudo trata da análise da produção científica brasileira sobre tecnologias de construção e edificações por meio de indicadores bibliométricos. A área foi escolhida em razão de sua relevância para o desenvolvimento econômico do país. A bibliometria é um método de análise quantitativa para a pesquisa científica. Os dados elaborados por meio dos estudos bibliométricos mensuram a contribuição do conhecimento científico derivado das publicações em determinadas áreas. Os indicadores de produção são úteis para o planejamento e a execução de políticas públicas, e para o conhecimento da comunidade científica sobre o sistema em que está inserida. O objetivo deste trabalho é estudar a produção científica brasileira na área da construção e tecnologia da construção civil a partir da análise de artigos científicos publicados em periódicos e anais de congressos indexados na base de dados Web of Science (WoS). Os dados foram coletados utilizando como critério de seleção a categoria "Construction & Building Technology", sendo analisados dados de 910 artigos de autores brasileiros no período de 1982 a 2014. A interpretação dos dados permite confirmar o expressivo crescimento da produção científica brasileira e da grande contribuição da região Sudeste para essa evolução.

The construction sector is responsible for some of the highest energy and natural resources consumption. In this context, new materials and solutions are created aimed at developing sustainable alternatives. While the literature presents papers that evaluate the mechanical and durability properties of concrete with glass waste powder and account for its environmental impact, no papers have executed the evaluation considering the retrofit of bridges. Furthermore, no papers evaluating the materials, construction, and maintenance could be found. Hence, this study proposes a technical and sustainable solution for the retrofit of the Third Bridge of Vitoria, an important intercity urban connector. This study evaluates both the technical and the environmental performance of structural concrete elements, considering the partial substitution of cement with glass waste powder and a baseline scenario with conventional concrete. The environmental impacts were evaluated through the life cycle assessment tool. The results indicate that incorporating waste glass powder in the prestressed hollow-core slabs as a partial cement replacement can improve the durability-related properties and mitigate environmental impact. It also shows that the manufacturing phase is the most impactful and that glass powder can significantly reduce the impact of maintenance.

Life cycle assessment (LCA) is a methodology that has been widely used to evaluate the environmental impact of products and processes throughout entire life cycles. In this context, the reuse of waste in paved road construction is a practice that has received increasing attention as a sustainable alternative to solid waste disposal. This article presents a systematic review of existing studies on the LCA of paved roads that incorporate waste reuse and proposes a guideline for LCA in this context. Several criteria were analyzed in the articles, and the results showed that only 5% of the articles followed all the recommendations set out in ISO 14040. The proposed guideline aims to provide guidance for future research and includes recommendations for each of the steps involved in LCA, from defining the objectives and scope of the study to interpreting the results.

Proper management of wood waste (WW) from the furniture industry has become an important issue. Life-cycle assessment (LCA) is a tool that is widely used for identifying environmental gains in WW management strategies. Thus, the aim of this research was to perform a comparative LCA, analyzing the environmental aspects and impacts of different WW management scenarios generated in the furniture industry in the state of Espirito Santo, Brazil. To conduct the study, five scenarios were designed: medium-density fiberboard (MDF) production (Scenario 1), medium-density particleboard (MDP) production (Scenario 2), solid ceramic brick production (Scenario 3), heat production in the ceramics industry (Scenario 4), and landfill disposal (Scenario 5). The results showed that compared to Scenarios 3 and 4, Scenarios 1 and 2 are potentially more favorable for disposing of WW. Scenario 1 achieved more environmental benefits in all of the impact categories evaluated. Notably, 1 m³ of MDF stores 1080 kg CO₂ eq/m³, which results in a net impact of −849 kg CO₂ eq/m³ of MDF. Scenario 5 is the least favorable practice. This research designs scenarios that contribute to reductions in the demand for virgin sources and increases in environmental gains.
