This thesis explores an innovative approach for the development of environmentally friendly cementitious materials based on Posidonia oceanica fibers and dredged marine sediments. The aim is to transform waste from the sea into valuable resources for construction. Research has resulted in a conglomerate with a low environmental impact, consistent with the requirements of sustainable building and in accordance with the principles of the circular economy. Through a series of laboratory tests, the rheological and mechanical properties of the mixtures were evaluated. The experimental results showed that the balanced use of Posidonia Oceanica and dredged sediments, as partial replacements for traditional aggregates, allows the realization of manufactured products with adequate mechanical performance and benefits in terms of thermal and acoustic insulation. This research offers new perspectives for the realization of environmentally sustainable building solutions, helping to reduce the consumption of virgin raw materials and mitigate CO₂ emissions, promoting a more responsible and environmentally friendly future.
La presente tesi esplora un approccio innovativo per lo sviluppo di materiali cementizi ecocompatibili a base di fibre di Posidonia oceanica e sedimenti marini dragati. Il fine è quello di trasformare i rifiuti provenienti dal mare in risorse preziose per l'edilizia. La ricerca ha permesso di realizzare un conglomerato a basso impatto ambientale, coerente con le esigenze del costruire in modo sostenibile e conforme ai principi dell'economia circolare. Attraverso una serie di test di laboratorio, sono state valutate le proprietà reologiche e meccaniche delle miscele. I risultati sperimentali hanno evidenziato come l’uso equilibrato di Posidonia Oceanica e sedimenti dragati, in sostituzione parziali degli aggregati tradizionali, permette la realizzazione di manufatti con prestazioni meccaniche adeguate e benefici in termini di isolamento termico e acustico. Questa ricerca offre nuove prospettive per la realizzazione di soluzioni edilizie eco-sostenibili, contribuendo a ridurre il consumo di materie prime vergini e a mitigare le emissioni di CO₂, promuovendo un futuro più responsabile e rispettoso dell'ambiente.

Abstract
This thesis explores an innovative approach for the development of environmentally friendly cementitious materials based on Posidonia oceanica fibers and dredged marine sediments. The aim is to transform waste from the sea into valuable resources for construction.

Through a series of laboratory tests, the rheological and mechanical properties of the mixtures were evaluated. The experimental results showed that the balanced use of Posidonia Oceanica and dredged sediments, as partial replacements for traditional aggregates, allows the realization of manufactured products with adequate mechanical performance and benefits in terms of thermal and acoustic insulation. This research offers new perspectives for the realization of environmentally sustainable building solutions, helping to reduce the consumption of virgin raw materials and mitigate CO₂ emissions, promoting a more responsible and environmentally friendly future.| File | Dimensione | Formato | |
