502 _aThesis (PhD) - Cyprus International University. Institute of Graduate Studies and Research Civil Engineering
520 _aThis thesis investigates the optimization of alkali-activated mortar by integrating nano silica, various fibers, and refining mix formulations. The study evaluates the impact of these components on the mechanical performance, durability, and chemical resistance of alkali activated mortar (AAM) through empirical methodology. Initial literature review identifies optimal proportions of fibers and nano materials for incorporation into concrete and mortar mixtures. Experimental work explores into the effects of mix parameters on mortar's performance, highlighting enhancements in mechanical strength and chemical resistance with the inclusion of fibers and nano silica. Optimizing mix proportions, especially the sodium silicate to sodium hydroxide ratio (SS/SH) and sodium hydroxide molarity, is crucial for enhancing AAM properties. The research also investigates the impact of various superplasticizers and the significance of precursor combination and content in achieving superior material qualities. Advanced statistical and machine learning analyses are utilized to uncover detailed relationships between mix components and AAM performance, informing the creation of optimized formulations. These analyses highlight the intricate interactions within AAM mixes and demonstrate that precise adjustments can lead to substantial improvements in material properties. Moreover, the thesis explores the impact of different curing conditions and chemical exposures on AAM, shedding light on its durability and resistance to environmental stress. By utilizing the CONCRETop optimization method, the research determines ideal mix designs for specific applications, striking a balance between mechanical properties, durability, costeffectiveness, and environmental impact. This approach not only demonstrates the adaptability of AAM in addressing various construction requirements but also presents opportunities for sustainable development in the construction industry. In conclusion, the thesis provides a comprehensive perspective on AAM development, highlighting the important influence of nano silica, fibers (basalt fiber, polypropylene fiber, carbon fiber, steel fiber, polyvinyl alcohol PVA fiber and polyester fiber), and optimized mix formulations in improving the material's performance. The discoveries make a substantial contribution to the construction materials field by suggesting a way to create more resilient, environmentally friendly, and high-performance building solutions. This study lays the groundwork for further progress in AAM technology with the goal of expanding its application potential and encouraging sustainable construction practices globally.
