Abstract
The study aimed to improve and reduce bacterial growth and environmental pollution by using ceramic nanoparticles powders included in cement mortar. Cement mortar modified by Nano-Composite Powders (NCPs) was fabricated in order to study the effect imposed by these NCPs on the biological, physical and mechanical properties. The NCPs that were used in this study are (CuO-MgO, CuO-ZnO, and CuO-CoO). These NCPs were prepared by the sol gel method. The results show CuO-MgO, CuO-ZnO and CuO-CoO NCPs give improvement in the physical, mechanical and biological properties to a greater extent than the control cement mortar without NCPs and specifically anti-bacteria and toxicity property.
After the discussion, the committee recorded its notes on the thesis, which were split between explanation and correction, and the student’s defense of her work and the discussion ended. The committee decided to evaluate the thesis and grant the student a doctorate degree with a full grade.
