Nanotechnology use to preserve the durability of archaeological brick buildings in Al-Najaf city

Archaeological buildings constitute the urban core of historical cities, supporting both private identity and urban life in society. Old Najaf city may be the most important city in Iraq due to its religious and spiritual value in the Islamic world; its archaeologic buildings thus represent the features of both collective memory and the private reality of cultural heritage. This research aims to achieve examine the use of nanomaterials in terms of contributing to the preservation of archaeological buildings built with bricks in Najaf City in particular, and Iraq in general, helping determine how to use these to prolong the life of these buildings based on the assumption that certain nanomaterials can prevent harmful environmental factors from affecting such buildings or causing further damage. This would allow a high level of environmental efficiency and help to perpetuate these historic buildings, as such treatments do not cause any changes in the original physical or chemical properties of heritage buildings. The study results suggest that Nano-treated bricks can effectively be used as a new building material for additive parts used to support archaeological buildings, thus offering access to buildings with high environmental efficiency.
