After the discussion committee recorded its observations on the thesis, which were divided between explanation and correction, and the student's defense of his thesis. At the end of the discussion, the committee decided to evaluate the dissertation and decided to award the student a master's degree with a full grade.
Abstract:
The study aimed to utilize geopolymer, represented by metakaolin material, treated with alkaline solutions (NaOH, KOH, and Na2SiO3), as an environmentally friendly alternative to conventional cement and brick for the production of geopolymer bricks used in thermal insulation. Nanomaterials (nano clay, nano zirconia, nano talc) were added to enhance its strength and reduce thermal conductivity. Mechanical and physical tests, as well as other characterization techniques such as FTIR, XRD, FESEM, EDX, and DSC, were conducted after 28 days of curing. The results showed an improvement in compressive strength, Hardness, and a decrease in the thermal conductivity of the manufactured brick samples.
