The President of Northern Technical University was a member and supervisor of the master’s thesis committee at the Technical Engineering College in Mosul. The thesis discussed an experimental study on sodium silicate waste as an alternative to river sand in geopolymer concrete.

The President of Northern Technical University, Professor Dr. Alia Abbas Ali Al-Attar, participated as a member and supervisor, in the presence of the Assistant President for Academic Affairs and a number of department directors from the university presidency. The thesis committee was held at the Technical Engineering College in Mosul, specializing in construction materials engineering technology. The thesis was titled: “Experimental Investigation on Sodium Silicate Waste as an Alternative to River Sand in Geopolymer Concrete.” The thesis, presented by researcher Omar Abdul Rahim Hassan, demonstrated the potential use of locally available glass waste by substituting it with conventional sand. Fine aggregate was replaced with crushed glass in various proportions, and the optimal percentage of WGS aggregate that could be used in place of natural sand was determined without affecting concrete performance. The thesis also outlined a study of the effect of different processing systems (the surrounding environment and the kiln) on the properties of geopolymer concrete. The thesis recommended using an ideal mix of 20% and replacing sand with glass in the production of geopolymer concrete, as well as fiber ratios. It also recommended using other ratios and various cases for further study.
The discussion committee consisted of:
Professor Dr. Maysar Muhammad Jumaa, Chairman
Assistant Professor Dr. Muthanna Adel Najm, Member
Assistant Professor Jassim Muhammad Abd, Member
Professor Dr. Alia Abbas Ali Al-Attar, Member and Supervisor
