- Modular system design for vegetated surfaces with alkaline activated materialsPublication . Manso, Maria de Castro Fonseca Morão; Gomes, João Paulo de CastroThe construction sector and mining and quarrying industries are the largest waste producers in the European Union, accounting for 35% and 28%, respectively, of the total waste produced. Therefore, it is essential to develop innovative constructive solutions based on the reuse of these wastes to create new materials with added value. This work presents the design of a modular system for vegetated surfaces with alkaline activation materials (Geogreen). The modular system stands out in the area of building materials, differentiating itself from other existing green roofs and green walls by its constructive characteristics, incorporation of industrial waste materials and integration of sustainability principles. The results demonstrate that this modular system contributes not only to the aesthetic function of a vegetated surface but also allows improving the thermal and acoustic conditions of the built environment. It contributes to the construction market with a more sustainable solution through the integration of waste materials and energy minimization.
- Applications of Green Walls in Urban DesignPublication . Virtudes, Ana L.; Manso, MariaGreen walls are a choice towards achieving sustainable urban rehabilitation, due to the lack of free space in the consolidated urban fabric. Nowadays, green walls are considered to be an innovation in the fields of ecology, horticulture or buildings. Nevertheless, in the domain of urban design, they are still surprising and unexpected ideas. Thus, this research aims to reflect on green walls as a feature in urban design and rehabilitation, identifying the advantages of their utilization as an enhancement of the quality of city’s image, especially in dense urban areas. It aims to demonstrate some practical applications of green walls in urban design proposals, showing model solutions and their real application in several architectural examples.
- Alkali-activation of tungsten mining waste mud blended with waste glass: reactivity, performance and innovative applicationsPublication . Gomes, João Castro; Magrinho, Manuel; Sedira, Naim; Beghoura, Imed; Humbert, Pedro; Manso, Maria; Fernandes, Ana; Silva, RafaelMines and quarries waste accounts for about 29% of the total generated waste from industrial processes and households in Europe. The reuse of mud tailings as precursor materials for alkali-activated binders and applications are very promising from a technical and environmental point of view. The aim of the present study was to develop added-value solutions to reutilize tungsten mine mud tailings in alkali activated materials. Some potential uses of these new materials obtained from alkali-activation of tungsten mud waste and other precursor materials, as well incorporating expanded granulated cork, such us a high energy efficient panel for a vegetated surface and a foamed lightweight brick wall, are presented.
