Physical-Mechanical Changes in Portuguese, Greek, and Italian Marbles Under Aging Cycles Simulating Environmental Effects Linked to Bowing

Abstract

Bowing, a significant form of decay, poses a crucial chal- lenge in the preservation of historical and contempo- rary structures, requiring comprehensive study and anal- ysis. This research focuses on the mechanical alterations induced by aging cycles of temperature and moisture on three distinct marbles (Portuguese, Greek, and Italian) emphasizing their susceptibility to bowing-associated effects. The prevalence of bowing in prominent histor- ical buildings underscores the urgency of understanding its underlying mechanisms and mitigating its impact. Through 50 aging cycles, this investigation discerns the distinct behaviors and properties exhibited by each marble, providing invaluable insights into the complex interac- tion between geological composition and environmental stressors. By highlighting the relevance of bowing and its detrimental effects on architectural heritage, this study underscores the importance of proactive measures in conservation and restoration efforts.
