Abstract
This study examines the use of heat-free femtosecond pulse laser technology for the cleaning of Makrana marble and semi-precious stones from the Soami Bagh Samadh temple in Agra, India. We determined the ablation thresholds of the semi-precious stones used in the inlay stonework with femtosecond laser pulses and demonstrated that laser ablation can effectively remove dust layers and environmental staining from the marble surfaces without damaging the original material. We demonstrated, by using optical microscopy, colorimetry, scanning electron microscopy and Raman spectroscopy, that femtosecond laser processing of surfaces reduced the risk of thermal damage due to minimal heat generation and allowed the preservation of the original surface structure. This research suggests that femtosecond pulse laser technology can be a sustainable and effective cleaning method for heritage places such as the Holy Samadh temple.

| Other | IABSE Congress New Delhi 2023 Engineering for Sustainable Development As the world population grows and the impact of climate change becomes more severe, the demand for sustainable buildings and infrastructure has also increased. Moreover, durable and resilient structures are crucial aspects of sustainable construction. The resilient and durable structures which can withstand the vagaries of natural disasters reduce the need for frequent interventions of repairs and replacements, thereby reducing the resources required for maintenance. To crystalise the way forward in the construction industry, The Indian National Group of The International Association for Bridge and Structural Engineering (ING-IABSE) has hosted this International Congress, on the theme “Engineering for Sustainable Development” in New Delhi on September 20-22, 2023. |
