| Summary: | <p id="p1">This chapter explores the primary degradation mechanisms observed in marble stones within heritage structures, focusing on flaking, spalling, uneven surfaces, mass loss, and staining. These manifestations are attributed to increased porosity resulting from various environmental exposures. A detailed analysis of these mechanisms is presented, with a particular emphasis on heritage structures in hot semi-arid climates, including the Taj Mahal in India. Thermal weathering emerges as the most significant factor contributing to marble deterioration in these regions. Laboratory simulations replicating the identified damage mechanisms provide quantifiable insights into their impact on the microstructure and pore structure of marble. Comparative studies between fresh and artificially weathered samples reveal decreased ultrasonic pulse velocity and increased water absorption, correlating with observed degradation patterns such as flakiness and mass loss. This chapter concludes with an overview of thermal weathering mechanisms, their manifestations, and the testing methods employed to quantify their effects.</p> |
