In this paper Nano powders were used a mono; copper oxide CuO and di metal oxides powder; titanium dioxide (TiO2) in fabrication of mortar. Powder particle size about (67.8 nm) for TiO2 and (55.7nm) for CuO with crystal structure tetragonal and monoclinic system respectively have been used. These Nano powders were used as additives to the mortar material (0.5, 2.5, 5, 7.5 wt %) in order to be used in construction application including covering building, and studies on these mortar. Investigation was done on the mortar including XRD, AFM, optical microscopy, physical and some mechanical properties, micro hardness and wear rate). Results shows that where there an increase in micro hardness and decrease in wear rate in the mortar with the addition of Nano powder. Also be reduced Ca(OH)2 soft crystals and formation fine grains structure and homogeneous and the abolition of flaws or cracks. And the mortar with the Nano addition has been improved, which make the addition of Nano material beneficial and have a promising future in modern construction application.
