Ways to Address Physicochemical Damage in Earthen Historical

The preservation of earthen historical buildings is a critical concern in the field of cultural heritage conservation. Over time, these buildings face a variety of challenges, including physicochemical damage caused by environmental factors such as temperature fluctuations, humidity, rainfall, and air pollution. This paper explores the methods and techniques for mitigating physicochemical damage to earthen structures. It discusses the mechanisms of deterioration, such as moisture absorption, salt crystallization, and soil erosion that primarily affect mud brick and adobe constructions. Additionally, the article highlights innovative preservation techniques, including the use of biological and chemical treatments, reinforcement materials, and protective coatings to enhance the durability and structural integrity of earthen buildings. The study further emphasizes the importance of sustainable practices in the conservation of these structures, considering both traditional methods and modern technologies. It aims to provide a comprehensive guide to engineers, architects, and conservation specialists in their efforts to protect earthen historical sites from further deterioration.
