AbstractIn this paper a lower ratio of two powders; nano and micro titanium dioxide (TiO2) powder were used as additive in fabrication of mortar. Particle size of TiO2 powder were (80nm,1.6µm). These powders were used as additive to the mortar material (0.05, 0.1, 0.15 %) by cement weight in order to be used in construction application include layering building, and studies its effect on the mortar.
Inspections of the mortar specimens including optical microscope, surface roughness, micro hardness as well as x-ray diffraction (XRD).
Results demonstrate that surface roughness was diminished with augmentation of Nano TiO2powder added more than micro TiO2powder substances, while micro hardness was increased by raising the option of Nano TiO2powder to the mortar more than micro TiO2powder. Also, the mortar microstructure with the Nano TiO2 powder has been enhanced more than micro TiO2powder, with increment in CSH phase, which make the development of mortar with TiO2 Nano material useful and have a promising future in cutting edge development application.
