In 28/1/2018, - On 28/1/2018 was discussed graduate student (master) Mustafa Thaer Hassan for his thesis titled “Manufacturing ideal material for exterior construction applications” had been discussed by commit which consist of following members.

The thesis had been scenically evaluated by Assist. Prof. Dr. Ziena  K. Abbas,  Baghdad University/ Department Civil Engineering, and Linguistically by Assist. Prof. Dr. Samir A. Amen, University of Technology/ Department of Mechanical Engineering.

The discussion took place at higher studies hall / building C, and master degree had been granted to student. 

The thesis discusses preparation nano materials by thermo-chemical spray method, where mono, and tri metallic oxides had been prepared, (zinc oxide, magnesium oxide, and aluminum oxide), from basic solutions with different molarity, (0.005, 0.1, 0.5), by spray at 750 Cº. The prepared powders had been tested by x-ray, Scanning electron microscope, particles size analyses, addition to densities which tested according to Archimedes theory. The prepared powders used to promote cement mortar characteristics, the base specimens was (1:2.75), cement to sand ratio. Nano powdersadded with different weight fraction, (1%, 2%, and 3%), at different particles sizes, (11.8،38.8،109.8) nm. The tests include viscosity and other: physical, thermal, and mechanical properties after (7) days.

The results show improving of properties for all specimens, consequently nano powders of these materials can be used to improve cement mortar used in external application like cover external walls of building and other external construction applications.
