The traditional building materials used in the various elements of the building are limited in their characteristics and characteristics, in addition to the presence of some defects which made it necessary to discover new materials that avoid the apparent defects in the building. The Nan particles, which have added to them a great effect in minimizing the defects found in traditional building materials Where the addition of the mat erial nana to obtain new features, were not available for several purposes vary from building to another, which is reflected in turn on the maintenance work of the building, and these materials 1- Titanium dioxide (TiO2) as self-cleaning material
2. Zirconium Oxide Nan particles (ZrOx) and anti-wall coating
3 - the use of Nan particles of silica as in the anti-fogging and anti-icing coatings
