Building materials faces many problems in Egypt, such as environment pollution. Pollution and human health
damage resulted from building materials, which is also a high consumption of energy, in addition to the low
efficiency of those materials, and the continuous increase of their prices, Under these circumstances we have to
rethink of new methods to reduce these problems. The current study aims to develop performance of the
building materials in Egypt by using nano technology. The research has adopted comparative analytical approach
which studied a local project that analyzed the used materials in the building, with a comparison between those
materials and nano materials.
