Mechanical properties and durability of compressed earth blocks incorporating n...
Turco, Chiara; Teixeira, Marta Sofia Aguiar Carvalho Oliveira; Teixeira, Elisabete Rodrigues; Mateus, RicardoThe construction industry urgently needs engineering solutions that reduce embodied carbon and promote circular material flows. Compressed earth blocks (CEBs) represent a promising low-carbon alternative, but their large-scale use is challenged by issues of mechanical strength and durability, particularly when natural materials are incorporated to improve thermal performance. Due to the inherent variability of ...
Social engagement in innovation for human-environmental futures: a brief reflex...
Pereira, Cláudia; Araújo, Emília Rodrigues; Teixeira, Elisabete Rodrigues; Urze, PaulaContemporary political and scientific discourses strongly emphasise issues related to the construction, communication, and contestation of the future. Nature-Based Solutions (NBS) represent high-impact social innovations aimed at reshaping practices and enhancing the resilience of infrastructures and populations through natural solutions. This chapter revisits the primary objectives of NBS and discusses the sig...
Aplicação do método de estado estacionário (hotbox) para a caracterização das p...
Paula Junior, Adilson C.; Jacinto, Cláudia Castro; Cosentino, Livia; Fernandes, Jorge Emanuel Pereira; Teixeira, Elisabete Rodrigues; Mateus, RicardoA atual crise ambiental e energética impulsiona a busca por construções mais eficientes e de menor impacte ambiental. Este estudo investiga a aplicação da hotbox, conforme normas ISO 8990 e ISO 9869, para avaliar o desempenho térmico de materiais de isolamento. Desafios experimentais, como controlo de temperatura e movimentação do ar e perdas de calor são abordados para garantir a obtenção de parâmetros térmico...
Thermophysical properties of compressed earth blocks incorporating natural mate...
Turco, Chiara; Abedi, Mohammadmahdi; Teixeira, Elisabete Rodrigues; Mateus, RicardoBuilding materials are responsible for significant CO2 emissions and energy consumption, both during production and operational phases. Earth as a building material offers a valuable alternative to conventional materials, as it naturally provides high hygrothermal comfort and air quality even with passive conditioning systems. However, disadvantages related to high density, conductivity, and wall thickness prev...
Influence of particle size on compressed earth blocks properties and strategies...
Turco, Chiara; Paula Junior, Adilson; Jacinto, Cláudia Castro; Fernandes, Jorge Emanuel Pereira; Teixeira, Elisabete Rodrigues; Mateus, RicardoIn the context of sustainable building development, Compressed Earth Blocks (CEBs) have garnered increasing attention in recent years owing to their minimal environmental and economic impact. However, owing to the inherent diversity of raw soil and the production process’s reliance on expertise, the properties of these blocks are subjected to multifaceted influences. Among these, the significance of soil partic...
Improving the mechanical, thermal and durability properties of compressed earth...
Paula Júnior, Adilson Campos; Teixeira, Elisabete Rodrigues; Mateus, RicardoInterest in utilizing industrial waste and by-products in construction materials is growing, given recent concerns about sustainable practices aligning with the principles of the circular economy. Within this context, compressed earth blocks (CEBs) are emerging as an alternative to traditional building materials, offering cost-effectiveness, energy efficiency, and reduced environmental impact. This systematic r...
Concrete production with domestic and industrial wastewaters: a literature review
Sheikh Hassani, Mohammad; Matos, José C.; Zhang, Y. X.; Teixeira, Elisabete RodriguesWith water scarcity posing an ever-present worldwide crisis, treated wastewater usage as an alternative to fresh water could be a smart choice and contribute to a sustainable construction industry. Numerous studies have been conducted by using treated domestic or industrial wastewater in concrete production, providing a promising solution to the global water shortage and wastewater management. However, the effe...
A systematic review of integrated frameworks for resilience and sustainability ...
Leal, Oscar Javier Urbina; Fekete, Alexander; Ramírez Eudave, Rafael; Matos, José C.; Sousa, Hélder S.; Teixeira, Elisabete RodriguesThere is a growing tendency to assess resilience and sustainability of critical infrastructures (CI), given the significant increment in high-impact natural hazard events affecting socio-economic welfare. Historically, these assessments have been conducted separately due to the independent evolution of each concept. However, recent contributions tend to integrate them. This paper provides a state-of-the-art rev...
Green concrete with glass powder — a literature review
Hassani, Mohammad Sheikh; Matos, José C.; Zhang, Yixia; Teixeira, Elisabete RodriguesThis paper represents a literature review of the effects of partially replacing cement with glass powder in concrete production, aiming to provide an enhanced elucidation of 78 published scientific articles between 2015 and 2023. Vigorous inclusion criteria were employed to accomplish this objective, such as focusing only on glass powder usage instead of cement, considering both conventional and unconventional ...
Spatial vulnerability assessment of critical infrastructure based on fire risk ...
Leal, Oscar Javier Urbina; Sousa, Hélder S.; Fekete, Alexander; Matos, José C.; Teixeira, Elisabete RodriguesOne of the most important factors when assessing the resilience of critical infrastructure is its vulnerability to extreme events. This study focuses on developing correlation maps that define the vulnerability to fire risk of critical infrastructure and its zone of influence. Using an index approach, a vulnerability assessment is challenging due to the fact that observing and measuring certain vulnerability as...
