This study evaluates the effectiveness of soil stabilization through a comparison between traditional cement and an innovative solution based on cement and ground mussel shells. The research analyzes the geotechnical properties resulting from stabilization processes - compaction, compressive strength, and bearing capacity under vertical loads - comparing cement-only mixtures with reduced-dosage mixtures incorporating mussel shells as a supplementary binder. Two representative samples from Rete Ferroviaria Italiana construction sites were employed: clayey sand and uniform sand.
Questo studio valuta l'efficacia della stabilizzazione dei terreni mediante un confronto tra cemento tradizionale e una soluzione innovativa a base di cemento e gusci di mitili macinati. La ricerca analizza le proprietà geotecniche risultanti dai processi di stabilizzazione - compattazione, resistenza a compressione e portanza a carichi verticali - confrontando miscele con solo cemento e miscele a dosaggio ridotto integrate con gusci di mitili come legante supplementare. Sono stati impiegati due campioni rappresentativi provenienti dai cantieri di Rete Ferroviaria Italiana: sabbia argillosa e sabbia uniforme.

Abstract
This study evaluates the effectiveness of soil stabilization through a comparison between traditional cement and an innovative solution based on cement and ground mussel shells. The research analyzes the geotechnical properties resulting from stabilization processes - compaction, compressive strength, and bearing capacity under vertical loads - comparing cement-only mixtures with reduced-dosage mixtures incorporating mussel shells as a supplementary binder. Two representative samples from Rete Ferroviaria Italiana construction sites were employed: clayey sand and uniform sand.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
