The Assistant President of the University of Technology for Administrative Affairs chairs a doctoral discussion committee in Materials Engineering Department

 The Assistant President of the University of Technology for Administrative Affairs, Professor Dr. Farhad Muhammad Othman, chaired a committee discussing a doctoral thesis in Materials Engineering Department tagged:

Optimization of sustainable blended concrete mixture modified with waste powder and improved thermal properties. 

The doctoral thesis by student Ahmed Tayfour Aziz aimed to improve the thermal and mechanical specifications of concrete by studying the effect of three factors: 

steel slag as an alternative to aggregate, glass powder as an alternative to cement, and w/b using test design and using the Minitab program.

Thermal conductivity, compressive strength, split tensile strength, dry density, EDX, DTA, XRD, XRF and SEM tests were conducted on 18 mixtures and were compared with the control sample.

 The results showed that these factors can be optimally used to improve the mechanical specifications and thermal insulation of concrete in a manner consistent with the requirements of modern construction.

The discussion committee consisted of Prof. Dr. Farhad Muhammad Othman, Chairman, and Prof. Dr. Ahmed Sultan Ali and Dr. Alaa Alaa El-Din Abdel Hamid and Prof. Dr. Waleed Abdel Razzaq Abbas and Dr. Muhannad Najah Jawad, members and Prof. Dr. Maan Salman Hassan and Prof. Dr. Alaa Abdel Hassan Attia as supervisors, as well as scientific evaluation of the thesis by Prof. Dalia Hikmat Hameed, from the University of Babylon, and Dr. Shatha Sadiq Hassan, linguistically by Dr. Nasir Abdul Hussein Nasser, all from the University of Technology.
