- Building insulation materials based on agricultural wastesPublication . Gaspar, Florindo; Bakatovich, Aliaksandr; Davydenko, Nadezhda; Joshi, ArpanEcological insulation materials of vegetable raw materials are increasingly widespread. The agricultural wastes can have an interesting role because their use allows the revaluation of agricultural wastes, whose disposal is a serious issue. This chapter gives an overview about the use of agricultural wastes on insulating materials. The source and characteristics of various types of wastes are described. The manufacturing processes considering the types of binders, including the main parameters involved, are explained. An overview is given about the properties of the insulation materials, including thermal conductibility, density, mechanical strength , hygroscopic behavior, acoustic and fire performances, and environmental performance. Suggestions regarding the future research needs are also presented.
- Development of fiber-reinforced earth-based composites for 3D printing in constructionPublication . Joshi, Arpan; Bártolo, Helena Maria Coelho da Rocha Terreiro Galha da Silva; Craveiro, Flávio Gabriel da SilvaThe construction industry is one of the prime users of global resources and a major contributor to global environmental impacts. Moving to a clean, circular economy can facilitate the achievement of the European Green Deal objectives, such as minimum environmental impacts, net-zero CO2 emissions and zero waste. The digitalisation of the construction industry, also known as construction 4.0, is a recent trend in the construction sector. 3D printing technologies has been mainly used to create cementitious-based construction components. On the other hand, earth is an eco-friendly natural material, used as a construction material since ancient times, though the investigation of the physical and mechanical behaviour of earth-based composites for 3D printing has been limited. This research work main aim was the development of 3D printable fiber-reinforced earthbased composites. The physical properties and the rheology behaviour was investigated for different formulations of crude earth-based composites was investigated, as well its structural stability, to get a better understanding of its feasibility to be used as construction components. It is crucial to further investigate different formulations of earthen-based composites for extrusion-based technologies, optimizing its processing methods. A Life Cycle Assessment (LCA) of these crude earth-based composites must also be performed to investigate its environmental and economic performance regarding other material formulations.
