Historical structures, often constructed using porous materials such as stone, brick, and mortar, have been exposed to environmental and anthropogenic stressors over centuries, leading to their gradual deterioration. Consolidation, a critical intervention in the conservation of porous historical materials, aims to enhance their mechanical stability, mitigate further degradation, and prolong their lifespan. This process becomes essential when the structural integrity of an artifact is compromised due to factors such as weathering, salt crystallization, and biological growth. However, the effectiveness of consolidation treatments is highly dependent on the selection of appropriate consolidants, which must meet specific criteria, including deep and uniform penetration, minimal surface residue, chemical compatibility, reversibility, and the preservation of the material’s breathability. Despite its importance, the field faces significant challenges, including a lack of standardized protocols and comprehensive understanding of the long-term performance of consolidants. This research seeks to bridge the gap between theoretical principles and practical applications by evaluating the performance of various consolidants on-site and optimizing intervention strategies for porous historical materials. The findings aim to contribute to the development of more effective and sustainable conservation practices for cultural heritage.
