Bowing, a significant form of decay, poses a crucial challenge in the preservation of historical and contemporary structures, necessitating comprehensive study and analysis. 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 historical buildings underscores the urgency of understanding its underlying mechanisms and mitigating its impact. Through 50 aging cycles, our investigation discerns the distinct behaviors and properties exhibited by each marble, providing invaluable insights into the complex interaction 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.
