Abstract(s)
The 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.
